When it comes to modern home networking, you have lots of options. You can use Wi-Fi or an Ethernet cable to connect your devices directly to your network. Each has its upsides and downsides, but which is best for you?
Read on for more information about the pros and cons of both Wi-Fi and Ethernet connections. What Is Wi-Fi? Wi-Fi is a technology that allows you to wirelessly connect devices in your home to a network. You can use it to connect your computer, laptop, smart TV, phone, tablet, and even smart home devices like smart lighting, thermostats, and security systems. There are two different types of Wi-Fi you can use: 802.11b and 802.11g. The differences between the two are that 802.11g offers a greater range, while b offers increased speed. The Wi-Fi standard you’ll find in most modern homes is 802.11n. How Wi-Fi Works The two most important factors when it comes to Wi-Fi are its frequency and the number of antennas. The frequency determines what band it operates on, while the number of antennas determines how many data channels a device has. For example, a dual-band router will have a 2.4 GHz band and a 5 GHz band. The 2.4 GHz band has a lower frequency and can transmit over a wider range than the 5 GHz band, which has a higher frequency and a smaller range. The number of antennas is important for a couple of reasons. First, the more antennas a device has, the more data channels it has. More data channels mean it is capable of sending and receiving more data at once. Two, the more antennas a device has the farther it’s capable of transmitting data. Dual-band routers usually have two or three antennas, while single-band routers usually have only one. What Is Ethernet? Ethernet is an old-school wired connection that can transfer data at very high speeds. Wired Ethernet connections are more reliable than Wi-Fi connections, which can occasionally drop. Ethernet cables are thicker than wireless antennas, so they are harder to tangle and can be placed in more permanent areas like on the floor or wall. Ethernet is good for transferring large amounts of data like downloading large files or transferring large amounts of photos and videos. How Ethernet Works The two most important factors in Ethernet connection speed are the type of ethernet network cables and the number of ports. Ethernet cables come in several types, with the most common being either a cat 7 ethernet cable or a fibre optic cable. The cat 7 ethernet cable is the type you’ll likely find in homes, while fibre optic cables are often used in businesses. And another type of cable that is used in ethernet is cat 8 ethernet cable. The number of ports on a device refers to how many devices can be connected to it at once. The most common number of ports is 8, but you can also find devices with 4 ports and 16 ports. Which One Is Best For You? We’ve looked at the pros and cons of both Wi-Fi and Ethernet connections, so which one should you choose? Which is best for you depends on a few factors. Some Factors If you want to download and upload large files, Ethernet is the best choice. If you’re connecting smart devices like home theatre systems, security systems, smart lights, and thermostats, Wi-Fi is the best choice. If you’re connecting lots of devices, Ethernet is the best bet. If you have limited wall space, you’ll want to use Wi-Fi. If you want a faster connection and less interference, Ethernet is the way to go. If you’ve decided you want to use Wi-Fi, you’ll need to choose a router and network setup. You have several options when it comes to routers, including a router/modem combo, a standalone router, and a mesh router system. You’ll also need to decide how many devices you’d like to connect, what type of internet service you have, and how much you are willing to spend. Conclusion The Internet is one of the most important aspects of modern life for most people. A home network is a great way to have fast Internet access throughout your home. Because there are so many options available today, you have lots of choices when it comes to setting up a home network. If you’re in the market for new networking equipment, look at the different types of devices. Then, decide which type of connection is best for your home. With the right equipment, you can create a home network that gives you fast Internet access throughout your whole home. Source: https://rentry.co/87civb

People all over the world use electricity, but the power cord used is different in various countries. If you are unaware about this fact and try to use the electrical equipment in those countries that use different power cords then it can damage your equipment or result in an accident.
Once you know types of power cords, you will be able to save yourself from accidents and save money on re-buying the things in case you change country. Before we start on the types of cords, first let us understand what power cords are. What are Power Cords? The power cords are the wires that transfer alternating and direct current. Mostly they are made of copper wires that are insulated with a non-conducting material like plastic. There are 15 types of plugs used worldwide starting from A to O. Let us understand the type of power cords in detail. IEC (International Electrotechnical Commission) IEC 60320 is the standard for power cord appliances with up to 250 volts that is accepted internationally. Most countries recognize the IEC 60320 power cord but still there are a few countries that use different power cords. The C in the IEC stands for code. The most common types of connectors in the IEC are C13, C15, and C19. They are usually found in data centers. These power cords have odd numbers for the receptacle and even numbers for the plug. The male appliance inlet is one unit higher than the matching female connector. For example, you will see power cord like C14 to C13 and C20 to C19. NEMA (National Electrical Manufacturers Association) NEMA cords are the benchmark for Americans as all the electrical appliances are made keeping in mind its voltage capacity and plugs. The most used cords are Type A and Type B. The Type A comes with two conducting blades or prongs whereas the Type B has extra grounding rod in it. The range of the power cord is 15 to 60 ampere and 125 to 600 volts. They are further categorized according to the classification. NEMA 6-15 power cord is usually used to carry current for large machines or household appliances. Every NEMA 6-15 power cord and NEMA 5-20p power cord comes with three prongs or blades. They also have different types of plugs. So, for example, if you need to use the plug behind a desk, you can go with a side facing head. The plugs of NEMA 5-20p power cord (Type B) have three different wires: neutral, hot and ground. The ratings are 15A at 250V even though they usually carry 110V. Europe: CEE 7/7 These are used by most countries in Europe. CEE 7/7 is the standard for the plugs. The other countries in Europe that use cords other than the CEE 7/7 are Ireland, Denmark, Switzerland, Malta and Italy. The most typical cords used for CEE 7/7 plug are CEE 7/7 to C13, CEE 7/7 to C15, and CEE 7/7 to C19. Other Types of Cords
Every electrical appliance that uses electricity will require a power cord. The specification depends on the voltage capacity and the type of cord. So, ensure that the quality of the power cord is good and is able to manage the voltage or else it can damage the equipment. This will ensure that the right amount of current is passing through the cord and the appliances will require less repair and the chances of accidents also reduces. Source: https://sfcableblog.wordpress.com/2022/05/19/3-main-types-of-power-cords-everyone-must-know/ We are moving towards an age where people are using laptops and tablets more than the computer system. But we have yet not given up using a computer system. There are certain professions that still prefer a system like IT companies, government offices, schools, etc
Talking about computer systems, one of the key challenges that most of you might have faced is during its setup. For a hassle-free setup, the most important thing to understand is computer cables. There are a lot of cables that run inside and outside the CPU. It is important to know them well in order to get the best quality output. Here we have discussed seven cables from which some are used inside while some are used outside the CPU for different purposes. Let us understand it one by one. Bi-directional Printer Cables A bi-directional cable means it can send real-time information from computer to printer and vice versa. Such communications enable monitoring printer status and print job scheduling even if it is distributing print jobs from multiple computers to multiple printers. Nowadays, most printers allow turning off the bi-directional option from the computer or from printer drivers. This way the printer gets some extra buffer resources for status checking, communication, and error reporting. DVI Cables Digital Visual Interface (DVI) is used to connect displays with the CPU. DVI cables deliver better picture quality compared to VGA cables. So DVI took the place of VGA cables. The main intention behind developing these cables was to transmit both digital and analog signals at industry standards. D-Subminiature Cables D-subminiature or D-sub or DB connectors are commonly used in communication. The name is derived from the fact that its shape resembled the shape of the letter D. It was developed by Cannon in the 1950s. The connector consists of two parallel rows of pins. Day by day it is replaced by USB connectors, but still, there are devices that use only DB connectors like computers, projectors, medical devices, etc. As these connectors have screws for the enclosure which help to create a solid mechanical connection. DisplayPort Cables DisplayPort is to transfer audio and video data over a singular cable. It is something similar to an HDMI cable. It can connect a display and graphics card, laptop, or computer. The resolution and refresh rates are high. DisplayPort has many advantages like strong manufacturing, greater bandwidth, and an explicit feature set. You can also manually set the resolution and refresh rate for the displays. Firewire Firewire is a connecting device used for connecting digital camcorders, hard drives, keyboards, digital cameras, etc. Firewire cable was developed by Apple and was the standard feature for many years of Mac computers. In recent years, Macs have been installed with a new interface called Thunderbolt. FireWire devices are also called hot-pluggable which means that without any power, they can be connected and disconnected. Null Modem Cable A null modem cable, also known as a cross-over cable, allows a head-to-head connection between two serial devices through their communication ports. It has a length limit of up to 30 feet. It is usually used to connect two computers in the same room for gaming or sending and receiving files. IDE Cables Integrated Drive Electronics (IDE) is an electronic interface standard. It defines the connection between a computer's motherboard and a disk storage device. One IDE ribbon cable connects one hard drive and a CD drive to the motherboard. It can connect two hard drives also to the motherboard. For successful implementation, the jumpers must be configured correctly. Conclusion Now that you know what cables go inside and outside the CPU, the only thing that remains is to ensure the quality of these cables. It is wise to buy good quality cables from authorized sellers. This way you will save your system from any other damage. To buy these cables online, you just need to search “firewire cables” or “IDE cables” or “Computer cables” and you will find the products with the pricing. Source: https://www.bloglovin.com/@sfcable/top-7-computer-cables-that-are-used-inside To build a network infrastructure for your small business, you need to consider a few things. It is quite different from setting up a home network. Business network designs are more complex and need high security. Here is the basic list of devices that you will need.
Modem A modem modulates and demodulates electrical signals sent via coaxial cables, phone lines, etc. Modulation is the transformation of digital information from your computer into analog signals to transmit over wires. Whereas demodulation is the translation of incoming analog signals back into digital information that a computer understands. Modems support DOCSIS(Data Over Cable Service Interface Specification) which is useful to transmit the internet over hybrid fiber-coaxial cable. But with the increasing use of optical fiber, modems have become obsolete. They transmit higher bandwidth over large distances. So if you need a high data transfer rate in your office then you will not need a modem. Router A router transmits packets of data to your device. So a router connects all your devices to the internet. You probably cannot use the routers that we generally use at our homes. You will have more connections like desktops, laptops, tablets, printers, guest devices, etc. in your office. So, if your business needs 20 or more connections you should probably invest in commercial or business-grade routers. Firewall As we have locks and security systems for our home/office, a firewall is the security system for your computer network. Based on the security rules you set, it monitors and controls the incoming and outgoing network traffic. Thus, it protects your network from unauthorized external access. Nowadays all electronic devices have firewall security but it is not enough to protect your confidential data from external attacks with just one layer of security. Thus, a dedicated hardware firewall works as an added layer of security. Just like a router based on the number of users, you can choose a firewall with enough capacity. Switch A switch is an important piece of hardware your office must-have. A switch allows you to communicate and share information between all your devices like desktops, laptops, printers, etc. Thus, switches are useful for interconnecting devices. Unlike home, offices need more ethernet ports because of multiple devices. There are two types of switches for small businesses to choose from. Unmanaged Switch This is the most basic type of switch as it can be used as it is without any configuration. It is less expensive but lacks some advanced features. It is a perfect fit for small businesses. Managed Switch The managed switch provides you control over the network. You can configure your switch and set port bandwidth, modify VLANs, etc. Managed switches are a little expensive and need some technical knowledge to operate. You can manage this remotely which makes them ideal for large offices. Ethernet Cable Now that you have all the hardware devices, it is time to connect them. Ethernet network cables are responsible for delivering sufficient bandwidth to your access point. There are various categories of ethernet network cables to choose from. For small businesses, Cat5e network cables are the way to go. If you are going to use devices that need high bandwidth, you can go for Cat6 cables which are slightly expensive when compared to Cat5e network cables. Other Hardware Devices Apart from the devices mentioned above, there are other things that you can install to upgrade your network to meet demands when you scale up. They are access point, repeater, patch panel, PoE, cable management, and network security implementation. Wrapping Up While building a network infrastructure for your business, keep in mind the space to scale. Once you have a clear understanding, invest in good quality business-grade devices that are most reliable and also scalable as and when needed.

They allow the connection between various electronic devices with the help of only a cable. Thanks to their versatile use cases, their demand is increasing every year. By versatile, I did not mean one USB cable fits all. There are different types of USB cables used for different purposes. For example, type A for one side connection, type B to and to understand each type, we need to know more details about them. Let us get started.
But before we dig deep into the types of cables, it is important to understand the following two terms: What is a Port and a Receptor Ports are basically slotting on the motherboard, where a cable of an external device needs to be plugged in. There are two types of ports: male and female. The device controlling the electric link is known as the host, while the other end is called the peripheral/receptor. For example, if you connect a laptop via ports to the smartphone, the laptop is the host here. A receptor is a device that receives the data/output result. For example, a digital receiver is a piece of equipment that receives digital programming from the port cable. It then converts that programming into a format that can be connected to a device and viewed on a TV set. Another example is when you charge your smartphones, the host is the USB adapters, and the receptor is your smartphone. USB Cable Types There are three types of USB cables based on the physical design of the ports and connectors - USB Type A, USB Type B, and USB Type C. USB 2.0 and USB 3.0 are the versions that deal with the functionality and speed of the USB cable. USB Type-A The most commonly used type of USB standard is Type A. This is commonly used with computers, media players, game consoles, TVs, power outlets, etc. Type A cable only goes into the port in one way, i.e., in the end that goes inside the host device's slot. USB Type B USB Type B connectors are typically used to plug-in peripheral devices such as smartphones, printers, or a hard drive to the host equipment. They are usually at the end of other USB Type B to USB Type-A cables. USB Type C USB C cables are a 24-pin USB connector system having a rotationally symmetrical connector. They are commonly used to charge portable devices like laptops, security cameras, and smartphones. Additionally, Type C is similar to the existing Micro-B USB variant that measures around 8.4 mm by 2.6 mm. This cable easily fits into the smallest peripheral sockets we use today. Plus, it allows 'reverse plug orientation, which means you can plug the cable either way round. It would be easy and highly convenient to use different electronic devices and connect them to one another. It is certain that in upcoming years, mostly all electronic devices will support Type C cable. On this note, let us know more about the technicalities of Type C cable. Technical Data of USB Type C Type C cable offers a maximum speed of 10 Gbit/s for data transmission and supports USB 3.1. It has a notable higher power output of up to 20 Volts 100 W and 5 amps. Thus cover the power requirements of equipment like laptops that consume 40-70 watts of power. Additionally, Type C offers a bi-directional power supply, i.e., you can charge the smartphone from the laptop and the laptop from the phone at the same time. Many smartphone manufacturing companies are now providing smartphones with type C plugs. Examples include the Nokia N1 tablet, Chromebook Pixel, 1 + 2, and Nexus 6P smartphones. I hope this article helped you understand the different types of cables and their working. You can now invest in an ideal cable type that fulfills your requirements. You must check the cable length and quality before buying any cables. Plus, you need to ensure that the USB adapters and USB cables synchronize with each other, otherwise, the current will fail to pass through the cables. You will also need to choose the right type of USB cable for your purpose like if you need to charge your phone, first you need to check what type of cable requirements it has. If it is a C-type socket, you will need a C-type USB cable with the supporting adapter to charge your phone. By following these instructions you can choose the ideal cable for your purpose. Source: https://www.bloglovin.com/@sfcable/what-are-different-types-usb-cables Do you also feel like you know almost nothing when it comes to installing wires in your new home? How many types of cables are there, and what is the purpose of using them? However, it is important to know which kind of cable you need for your electronic devices.
Also, having a basic understanding of various cables can be helpful while choosing the right kind of cables for your home. Mostly the word wires and cables are interchangeably used but the cable is a collection of various wires. However, they have the same purpose of carrying electric current. Let us find out what kind of wires your home requires. Non-Metallic(NM) Cable NM cable is the most common type of cable. The composition of these cables is copper wire and two or more insulated wires. The copper wire is also known as a ground wire. Ground wires protect the circuit from getting damaged when there is a sudden surge of current. The ground wire will supply that current to the earth. These wires are color-coded, which means the outer jacket of the cable is in different colors to indicate wire gauge. The general range of gauge is 14 gauge to 6 gauge. Also, these cables operate in dry conditions. Underground Feeder(UF) Cable These cables are made for wet places and require direct burial. They have a solid sheath that wraps up the wires completely. UF consists of hot insulated wire and neutral wires. They produce higher voltage and are for major circuit wiring. These cables are easy to identify as their sheathing is solid plastic and is gray in color. You can use this cable for outdoor lighting of your residence like lampposts. Phone and Data Cable This cable is useful for landline telephones and internet(broadband) connections. Generally, Cat5 cable is installed in homes. They have eight wires wrapped together in four pairs. They are used for both data and phone transmission and offer greater quality and capacity than standard wires. Although this wire has a small amount of voltage, it is considered safe when it is below 30 volts. However, it can be dangerous when it comes in contact with other wires. So, you should avoid data cables touching other household wires. Coaxial Cable It is a cable with jackets with an inner conductor wrapped in a tubular insulating layer surrounded by a tubular conducting shield of braided wires. Once, coaxial cables were the standard for connecting televisions with antennas or to cable delivery services. It is still used for connecting with satellite dishes or subscription television services. It is round in shape and is generally of black or white insulation cover. Nowadays, people are moving towards HDMI cables for TV data transmission, but if you still have older subscriptions or satellite dishes, you can install a coaxial cable. Combined Cable Composite wires or combo wires are the easiest way to run multiple audio, video, and data cables without having to do multiple pulls for each. They come in a combo of Cat52/RG6 and Cat5e/16AWG audio combo. You can order bulk network cables, and they usually come 500ft long. To save yourself from the mess that multiple wires might create, you can invest in good-quality composite wires. It is easy to manage and hide making your place look much cleaner and more organized. Buying bulk network cables can save you a decent amount of money. Conclusion Choosing the right electrical wires can make a big difference to your home. Make sure you purchase good quality cables from suppliers who provide a lifetime warranty for the cables. Wiring is a one-time thing, so make sure you do it right the first time. Source: https://www.bloglovin.com/@sfcable/5-types-wires-every-home-needs . There are times when computer cables might seem confusing and all the same. It becomes hard to distinguish which one is useful for which purpose. Today, I have a detailed article for you with all the necessary information about three main types of computer cables. This will help you to understand each and distinguish them. So, let's start exploring about the three primary and popular computer cables:
1. USB (Universal Serial Bus) These are the most common and versatile computer cables. You can connect almost every computer peripheral device like keyboards, flash drives, mice, headsets, wireless adapters, etc., to the computer via a USB port. These cables have multiple versions, or should I say they have evolved in multiple versions with varying speeds. USB 1.0 It can transmit data at a speed of 1.5 MB/s. USB 2.0 It can transmit data at a speed of 60 MB/s. This version is compatible with older versions of the USB. USB 3.0 It can transmit data at a speed of 625 MB/s. This version is also compatible with previous versions. USB 3.1It can transmit data at speeds of 1.25 GB/s. This cable is compatible with all the previous versions of the USB. Additionally, this version is the most popular type out of all versions. USB 3.2 It can transmit data at speeds of 2.5 GB/s, but there is a condition. You need to use a USB-C connection to have this speed. It is compatible with all the previous versions of USB cables. USB 4.x It is a USB cable that can transmit data at speeds of 5 GB/s while using a USB-C connection. It is compatible with USB 3.2 and USB 2.0. Also, while choosing a computer cable adapter for these ports, you need to check if it is fully compatible with the port or not. Otherwise, it could affect the speed of the cable. 2. HDMI (High-Definition Multimedia Interface) Cables High-definition broadcasts are the standard cables for achieving high-quality video. Before HDMI, there existed VGA and DVI, but they only allowed video signals to transmit through them. In contrast, HDMI allows both audio and video signals to transmit through it. These are digital signals, which is why HDMI is compatible with only newer devices. But we are seeing that companies are making devices that support HDMI port for enhancing their customer's experience. HDMI connections come in different types as per your purpose: Type A This is the most popular HDMI cable. You can easily identify it by its male head with 19 pins/ It is compatible with only single-link DVI-D connections. Type B This type is larger than Type A. It has 29 pins and a male head. It is compatible with only dual-link DVI-D connections. This type is not seen much in the market. Type C It is a 19-pin connector. This is useful for connecting portable devices like mobile phones, digital cameras, etc. Type D This cable has 19 pins and looks quite similar to the previous USB cable. It is mostly useful for mobile devices like tablets and smartphones. Type E This is a much larger cable with a locking mechanism. It is primarily used in automotive applications. 3. Ethernet If you have ever tried to install or fix your home Wi-Fi router, then you have likely dealt with an Ethernet computer cable. Ethernet cables are popularly useful for setting up local area networks. It looks unique, and it is easy to distinguish it from other cables. In most cases, these cables are used to connect routers to the modems and computers. You can also connect two different devices by using a crossover Ethernet cable. It also has different versions to fit your purpose: 10BASE-T Ethernet This is the oldest and most common type of Ethernet cable. It supports data speeds of 1.25 MB/s. 100BASE-TX Ethernet This is the same as the previous one except that it supports speeds of 12.5 MB/s. 1000BASE-T Ethernet This is one of the most popular types of Ethernet cables used in our homes. It supports data transmission at speeds of 125 MB/s. 10GBASE-T Ethernet This cable uses Cat6 wiring to support data speeds of 1.25 GB/s. Wrapping Up I hope this article helped you with knowing more about computer power cables. Now, when you see a cable in your home, you can know if it is Ethernet, HDMI, or USB (with types). This knowledge will also help you in your business to invest smartly in the cables that are necessary. For instance, if you own an automobile business, then HDMI type E is an ideal choice for you. Additionally, while you choose computer cable adapters, ensure that it is compatible with the type of cable you have. Source: https://www.bloglovin.com/@sfcable/3-primary-types-computer-cables-you-need Let’s admit the fact that our laptops never come with enough ports. Especially for Macbook Air users, it becomes compulsory to carry an array of dongles so that it can get easier to plug everything in with USB cables and other products.
Enter USB hubs. That makes everything much easier. It not only expands the number of ports, but with USB docks you can set up your perfect dream workstation with a single plug! Today, we will talk about some of the best USB hubs that can be of the best use for you. However, you must be wondering if there is any difference between USB hubs and docks? Well yes! There is a thin line since they technically do the same thing. However, there are some differences that you need to consider before buying them. Basically, USB hubs are smaller, and cheaper dongles that add extra USB ports, SD card readers, display outputs, or a headphone jack. These don’t supply extra power which means you will not be able to change gadgets plugged into them. These are also portable so that you easily carry them in your laptop bag on the go. On the other side, USB docs are larger, more expensive, designed to lay on your desk. They come with their own power supply so that you can easily charge other devices/ You can also use them to connect your keyboard, mouse, monitors, etc. to your laptop at once.

Source: https://www.bloglovin.com/@sfcable/top-3-usb-hubs-for-all-your-gadgets We all prefer wifi because we love the freedom that comes with it. We can access the internet anytime without much effort. With wired connections, some people don’t like the mess ethernet cables create. Sometimes we also have devices that are not compatible with LAN ports.
But, if you have to deal with confidential data and need a more reliable, fast connection, then you must think about getting a wired connection for yourself. Also, wired connections have less latency compared to wifi connections. This article explains everything about how a wired mess(wired connection) can be better than a wireless connection. Wired Connections are More Secured Wired connections are more secured compared to wireless connections. Here are some use cases and examples to understand the why of it. First, let’s understand how wireless connections work. A wireless connection uses radio frequencies to send signals between devices. It uses the gigahertz range to send and receive data. So, you don’t need a wire to connect to the router for the internet. Now, the issue is that it is easy for hackers to hack radio frequencies. Although wifi connections are encrypted with WEP, WPA, or WPA2 protocols, there are chances your connection can get compromised. For example, hackers hack institutes' data, who are already paying tons of money to protect their connections. With a wired connection, all the data is sent and received through ethernet cables. So, if anyone wants to get into the system, they need physical access which can be tough most of the time. This reason makes wired connections more secure than wifi connections. Thus, organizations dealing with confidential data tend to stick to wired connections. Wired Connections are Faster You might be thinking that radio frequencies will be transmitting signals faster than ethernet cables. But the reality is different. In reality, wired connections are faster than wifi. In a wired connection, a cat 6 ethernet cable can achieve 10 Gbps speed. For wired connection average upload speed is 60Mbps, and download speed is 30 Mbps. The maximum speed of the ethernet cable depends on the type of cable you use. For example, cat5e cable supports upto 1Gbps. With wifi connections, for 802.11ac standard, the maximum theoretical speed is upto 6.5Mbps. But the actual speed is usually less than 1 Gbps. Whereas for wifi networks, the average upload speed is 20 Mbps, and download speed is 15 Mbps. So, there you go! Wired Connections are More Reliable The radio waves used by wifi connections can be interrupted quickly. Data loss, lag, connectivity issues are some common issues faced with wifi. You must have experienced that some areas of your home don’t have proper wifi connectivity. It is because the walls disrupt the radio signals, and thus, the corners or areas far away from the router lack uniform connectivity. Wired connections are highly reliable as they don’t face issues, as mentioned for wifi connections. If your cable is connected to your computer, it will provide you with constant speed. The only time the wired connection is interrupted is when the ethernet cables break or power outage. Wired Connections have Less Latency We can also determine the quality of connection by latency. Latency is the delay by the signal to reach the destination. Latency is noticeable when dealing with large files, streaming 4k videos, playing games, etc. So, if your work demands constant and fast connection or you want to play high graphic games, choose ethernet cables as they have less latency compared to wifi. Conclusion Now that you know how wired connections are better than wireless connections, if you are considering setting up a connection for your business, then you should invest in cat 6 ethernet cables.

The right selection of power cords not only matters to the cost of the data center installation but also to its performance. Using good quality and the right type of power cords is of utmost importance.
Generally, for the data center the C13 power cord, C15 power cord, and C19 power cord are popular for their use. For more tips and information regarding how to manage data center power cords, keep reading! Know the Equipment The first thing we need to figure out is the maximum power voltage for the equipment. For connecting multiple devices, calculate the total power and then choose the connecting plugs. The next thing on the list is the connector type of the equipment to determine the power type. For different countries, the standards for connectors of powered equipment and power cords are different. So, different types of connectors have different specifications. Like the international standard IEC, NEMA, Schuko/CEE7,BS1363 UK, etc. Among these, the IEC power cords and the NEMA power cords are suitable for the data centers. The most common IEC outlet type in data centers are the C14 to C13 power cord, C14 to C15 power cables, and C20 to C19 power cord cables and the most common NEMA power connectors are NEMA 5-15P. Colored Cords for Easier Management As you know you will be dealing with lots of cables, different colored cords are suggested to organize and maintain high-density cables easily. Colors provide quick visual identification. To simplify cable management, it is better to have different colors for power cords. For example, you can differentiate side A cords from side B power cords to identify and organize dual power feeds for redundant power sources. Similarly, for data cables, you can color code to identify roles or functions of the cable or the type of connection. You can also label the cables. This way your data center manager will save a lot of time spent tracing your data center cables or unexpected disconnections while moving equipment from one place to another. Calculate Cord Gauge and Length The extension cord’s load capacity i.e. the ability to carry current is determined by the cord gauge and the length. What is a cord gauge? The cord gauge is the size of the wire based on its cross-sectional area. In the US, the method of notation is American Wire Gauge(AWG). A lower AWG number means the wire size is large and the capacity of the cord is also high. For example, 14 AWG power cords are thicker and able to carry more current compared to 16 AWG power cords. Using a thicker cord is a wise decision keeping in mind the future of your data center. On the other hand, for cable length, the shorter the power cord, the less the power loss. Power extension cords are 2 feet to 30 feet or even longer in length. But it should not exceed 100 feet to prevent power loss and overheating. So as length increases, the power cord will deliver less power to the connected devices. Thus, while using high amperage ratings, it is better to use the power cord with less length. In order to cover a longer distance, you must upsize the power cord. Angled Connectors to Save Space To save space and improve airflow to servers, you can use angled connectors. There are various options like up, down, right, left, and 45° angle options are available for connections within high-density racks. With proper organization, you won’t have to disconnect the power cord when working in a high-density space. Conclusion Cable management does not have to be complicated. With the right information and guidance, you can go a long way. We hope you will find these data center power cords management tips helpful. We assure it will significantly contribute to the continuous uptime of your data center.

So that means everything will magically work wonderfully together, right? Right?
Obviously not. It means we have to wait for the concept-like products to launch all through the year and hope that they work as advertised. One of the things that are underrated to work as well as advertised is perhaps the HDMI cable. And that is because there is nothing wrong with the cable but rather which version of it one is using and what they are connecting with it. There needs to be perfect compatibility between the HDMI cable, and the input-output devices. Again, sometimes there is no HDMI port in devices, so you have to resort to HDMI adapters, and even with those, finding the best compatible one can be challenging. The HDMI Licensing Administrator, the body that certifies HDMI versions and standards, says that your latest TV which says it supports HDMI 2.1, is actually not really required to offer any of the 2.1 features. The versions of HDMI suggest the features they have and support, thereby being an important factor for any gadget purchasing decision. Television or home entertainment systems are, after all, things that customers buy for many years on end, and future-proofing on what connectivity standards it supports, matters a great deal to that. Here’s a breakdown of all the features for each version: When it comes to adapters, HDMI adapters are mainly used when you don’t have the port itself on your gadget, namely when your device is either too old or too new. Years ago, a DVD player came with RCA ports and now some of the most popular laptops come with only USB C ports. In either of these cases, you need an adapter. You’d need an old DVD player if you want to occasionally watch a DVD without buying a new, plug and play player. Just get an HDMI to RCA adapter and you should be able to watch your DVD. Similarly, if you want to plug in your laptop with USB C to your TV because your TV is not new enough to accept screencasting, you need a USB C to HDMI adapter or a USB C hub to do the trick. CES might as well be known as the TV show because that is often the main attraction there. Display technology scaling to show off minuscule pixels, freestanding TVs, wall-sized panels, modular display panels, and whatnot. It also shows off projectors of varying dimensions. While the concept and show of the whole thing are commendable, not everything is affordable by the average consumer. This especially holds true in the ports that get shipped on TVs. The latest standards are always expensive and the mid-tier TV variants may not always ship with those to cut down on cost. When choosing any display for yourself, TV or monitor, or projector, consider the longevity of the same. Are you going to be able to use these ports for years to come as you upgrade the other parts of your workflow? If the answer is yes, get the display. But remember to not read the details of each part of the gadget before buying it.

You can try with testing tape so that you don't lose your valuable recordings in case of any equipment malfunction. Step 1: Follow the instructions given on software to start a new project. Step 2: Place your computer and VCR near each other and connect them with a video converter. You will need to attach RCA cables from VCR output to the input jacks of the converter. The wires are color coded so that you attach them correctly. Red and white wire is for audio and yellow is for video. If you have a VCR that enables S video cables then you can attach it instead of a yellow video cable as it will give slightly higher video quality. Step 3: Plug the converter into the USB port of your computer. Step 4: Insert VHS tape and rewind it. Step 5: Start the video converter software and follow the instructions. Press play on the VCR and record button in the video converter software. The video will play and record in real-time. So, depending on how long the video is, it will take the same amount of time for conversion. Step 6: When it is done, stop recording on your computer and let the software save the file. You can backup this file on any cloud service to ensure you don’t lose data. Wrap Up We hope this article helps you in relieving your old memories by converting your old VHS tapes to video files. Now you can easily watch it anytime, anywhere.

Some parts can be directly plugged into the motherboard of the computer, while some parts need external cables or computer adapters to connect them to the computers. These parts include mice, keyboards, digital cameras, hard drives, etc. There are several types of different cables available in the market, such as HDMI cable, DVI cable, VGA cable, Ethernet cable, USB cable, 3.5 mm audio cable, PS/2 cable, and computer power cord. Let's deep dive to know about the types of computer cables so that you can choose the ideal one as per your requirement.
1. HDMI Cable A high-definition media interface (HDMI) is a computer cord used to transmit high-definition audio and video signals. Using this wire, the audio and video signals are easily transmitted. Additionally, these wires do not hamper the quality of images, thus sending clear videos and audio. The HDMI cables are useful in connecting cable boxes, DVD players, TVs, etc. You can connect all types of AV devices to one standard cords - HDMI cable. Furthermore, one HDMI cable is enough for transmitting audio and video signals at the same time. 2. DVI Cable Digital Visual Interface (DVI) cords are useful for connecting the LCD monitor to the video card. With this cord, you can see high-quality images without any network disturbance. This cord was commonly used in CRT monitors with a VGA connection. It transmits the digital and analog signals to the computer system. The DVI wire is capable of both digital and analog connections. Users can easily differentiate between the analog and digital DVI wire by looking at how many flat pins are present on the cords. If a flat pin has four pins around it, then it is a DVI analog, and if there is only a flat pin, then it is a DVI digital cord. 3. VGA Cable Video Graphics Ray (VGA) cable is useful for sending video signals and to link the monitor with the CPU of a computer. You can use the VGA wire on HD televisions. There are 15 pins in the plugin cable divided into three rows, thus each row has five pins. You need to fit one end of the cord into the monitor and the other end in the CPU. 4. Ethernet Cable The Ethernet cable is useful for connecting a wired network. The Ethernet cable connects the switches and monitors to the LAN (Local Area Network). This cable looks like a phone cable but with more wires. A user needs to plug in the ethernet cable in the ethernet port present on the motherboards. It has eight wires that are available in different colors. You need to check its length and durability to determine the quality of the connection. If your Ethernet wire is too long and not durable, then it will deliver only poor quality signal. 5. USB Cable Universal Serial Bus (USB) cord is a standard cord useful to connect both universal devices and personal computers. It is commonly useful for short-distance digital communication. You can transfer the digital data using a USB cord. You can even charge electronic devices like smartphones, trimmers, Bluetooth speakers, etc., via USB wires. It can also be useful to connect two devices directly. In computers, the USB wire is connected to the USB port. Even the mouse and keyboard are connected to a USB port with USB cords. 6. 3.5mm Audio Cable These audio cords are useful to make the audio of the computer audible. It is also useful for connecting a mini-stereo audio device, portable CD player, etc., to any multimedia speaker. One can also connect earphones and headphones through the cable. 7. PS/2 Cable The personal System 2 (PS/2) cable is a standard cords used to connect the keyboard and mouse to the computer system. The length of this wire is long enough to accommodate you for easy connection of mouse and keyboard to the computer. It has six pins and a round connector. It has two basic sizes, the smaller one is a common wire that some computer adapters use to convert it into a large size. Conclusion Every type of computer cord has its own numerous advantages and can be useful for different requirements and purposes. Additionally, all the computer cables are standard cables. This means that users can use them to connect to any system. However, the cable's performance depends on the quality of the cords. Thus, it is advised to prefer reputed online wire selling companies. The perks of it include excellent performance, warranty cards, and good services. Source: www.bloglovin.com/@sfcable/7-types-computer-cables-you-need-to-know |
