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.

We often find ourselves in the situation of moving a lot of data between a bunch of devices. This time, the USB hub can be of great help. For example, if you want to back up photos from a computer, tether your mobile phone to use mobile data on your PC, print some documents, and upload music to your iPad, a good-quality USB hub can help you do all of that at the same time. For any technology enthusiasts or gadget fans, having as many USB ports as they can is like a luxury. So, if you're always unplugging devices to make room, the USB hub is your champion. 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 speed it provides will allow you to use devices that require fast internet speed; if you don’t have such a requirement, you can also purchase cat5 or cat5e 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.
