Ethernet cables have been in existence for decades now. We can probably not think of the Internet existing without them. Electronic Industries Association and Telecommunications Industry Association (EIA) standardized them.
They are available in following shield formats:
Cat5 cables use twisted pairs to prevent internal crosstalk, XT and for external wires it uses AXT. These cables use 1.5 to 2 twists per centimeter. Talking about Cat5e cables they got recognition by TIA/EIA and define TIA/EIA -568 as the latest version in 2001. It slightly has a high frequency specification which Cat5 cable extends up to 125 Mbps. Remember similar to other Ethernet cables you can find shielded CAT5e cable. Cat5e is useful for 100Base-T and 1000Base-T Gigabit Ethernet and is a form of Cat5 cable but manufactured for high specifications. It conducts tests at higher specifications to ensure that it can perform at higher data speeds. The twisted pairs within the network cables normally have the same level of twisting. Now, let's talk about Cat6 Network Cable:It is the sixth version of twisted pair Ethernet cable and supports the Gigabit Ethernet Data rates i.e. 1 gigabit/second (Gbps). It has four pairs of copper wires and you can utilize these copper wire pairs for signaling and obtaining superior quality performance. The best part about it is that it can support 10 Gigabit Ethernet connections for distances of 50 meters or 64 feet. Enhanced version of CAT6 is CAT6A and it can support the speed up to 10Gbps. Similar to previous versions of Ethernet cables, CAT6 cable also uses RJ-45 standard connector. Now, let's talk about the difference between them: Difference: CAT6 and CAT6A cat6 network cable supports 10 Gigabits Ethernet and covers distance up to 50 meters. Whereas, CAT6A enhances the performance of CAT6 cables. It also supports 10 Gigabits data on a single cable run but covers distance up to 100 meters. Twice the speed of CAT6. Cost of CAT6A Ethernet cables is more compared to CAT6 and is thicker in density. It uses standard RJ-45 connectors. Difference: CAT6 vs. CAT5e To improve the previous versions of CAT5 cables, two key areas were developed. One was development of CAT5e i.e. CAT5 enhanced and the other one was CAT6. Still, CAT5e lacked some technical enhancements which CAT6 overcame. If you are thinking of purchasing a cable which supports Gigabit Ethernet installations at lower costs, then CAT5e is a good choice. CAT5e cable offers good performance for Gigabit Ethernet at cost effective rates. It is widely known for wired Ethernet installations. Quite similar to CAT6, CAT5e also utilizes a four wire pair signal to provide smooth data rates. On the other hand, Cat5 cable has four wire pairs out of which two remain inactive. Going further, let's talk about the advantages of each of the above mentioned Ethernet cables:Cat5 Cables:

Travel adapters and converters are necessary while travelling internationally with electronic devices. However, voltage and outlet type vary from destination to destination and the differences between the various converters, transformers, and adapters can confuse even the most seasoned international travelers.
This guide to travel adapters will help you determine which types you need for your next trip abroad:What is a travel adapter?Countries across the world use different outlets and exact configurations of these outlets vary by country. If you are traveling abroad, chances are high that you'll need an adapter to plug in your electronic devices. However, these travel adapters often do not convert the power supply coming from the outlet; they simply allow you to plug your device into the configuration of that specific foreign electrical outlet. What are Voltage Converters and Transformers?Just like outlets, different countries use different voltages and many of our electrical devices cannot withstand these different voltages. Eg: in the United States electricity runs on 110-120 volts, while in some countries it is 220-240 volts. If your device is not dual voltage or multi voltage, it either needs a travel converter or transformer. To determine if you need a converter, first check your device for the voltage mentioned on it. Old hair dryers are generally single voltage, whereas, newer hair dryers are generally dual voltage. For dual voltage devices, you may only need to flip a switch to a higher or lower voltage. Multi voltage items like new laptop computers and smartphones automatically detect and switch voltages. Dual voltage and multi voltage devices do not require a converter. However, single voltage items do require a converter or transformer to function. If you plug on one of these items to a simple travel adapter, it might cause the device to break or even worse. To complicate things more, different single voltage devices require either a converter or transformer. Electric devices that use heating elements, like a hair dryer or curling iron, require a converter. Electronic devices that use circuits, chips, or a motor based transformer. If you want to simplify things then there are travel adapters that convert voltages. Just check the adapter for various voltages it can safely handle. Simple power outlet:Currently there are 15 different electrical outlet configurations useful around the world. Some plug tropes are useful throughout the entire continent whereas others are limited to a single country. There are many universal adapters available that are compatible with multiple outlet configurations. But, they often leave multiple plug types. There are various types of power plug adapters like c13, c14 power plug and many more. Here, we are going to talk about the first three types of the most common outlet types abroad. You can find the most common socket types with common universal adapters:

Why? Because they require active adapters instead of passive adapters. Let’s Understand What's Inside These Adapters And Converting The DisplayPort To HDMI Is Easy:HDMI and DisplayPorts were created by two different consortiums and serve different purposes. HDMI cables were created for displays like HD TVs, projectors, etc. On other hand, DisplayPorts are useful for video sources like AV receivers, computers, etc. DVI, HDMI, And DisplayPort:First talking about similarities between DVI and HDMI connectors. HDMI was created as a descendant of DVI and they both were the same at the beginning. They use technology named TMDS (Transition Minimized Differential Signaling) to transfer data. With the help of a simple connector type adapter you can switch from DVI to HDMI and vice versa. You can do this to the single link DVI which supports resolution up to 2048 x 1200. If the resolutions are above HD, then high speed HDMI converts to dual link DVI. Hence, it's better to use an active adapter. Remember, HDMI supports digital audio whereas DVI supports only video standards. If you are using audio and video then you can either use a DisplayPort to HDMI adapter or connect the audio to the display in a different way i.e. using a headphone jack. On the other hand, DisplayPort uses another signal type technology and a low level cable voltage. How To Translate Using DisplayPort Dual Mode?It uses the simple adapter named DisplayPort Dual Mode or DP++. It’s an optional feature and available on most consumer device video cards. Usually, you can find DP++ logos on the device but because it's widespread now consumer products don’t mention the logo. Working: When a DP++ device detects an HDMI adapter attached to it, the graphics card or graphical processing unit (GPU) automatically translates and sends HDMI - TMDS signals via video output. The pins of the DisplayPort are connected to HDMI connectors this makes the transition simpler. It is an easy plug and play and does not need any driver to work. Further, if you want to connect multiple DVI or HDMI monitors to DisplayPort output, you will require an active adapter or splitter as well. Graphics card does not support DP++ output if it’s multiple monitors. In such scenarios, check with customer service of the graphics card manufacturer for the type of adapter that fulfills your requirements. Coming Back To HDMI To DisplayPort ConversionHDMI cables do not support force signal translations in GPUs. Hence, we need an adapter with some computing power which computes at the connection. This is one of the major reasons to use an active adapter. When we convert DP++ it means that every screen or a projector should have an HDMI interface? No, it does not because it's better to connect devices using the same protocols. Firstly, the voltage level shifter circuit should pose a restriction on the speed of the adapter. New adapters become available whenever you increase the bandwidth, but you need to buy the appropriate model. however, this applies only to single link DVI connections because dual link DVI signal needs 25 pins. And so you cannot transmit from the DisplayPort connector using a passive adapter. Hence, you need to go with an active adapter to make all the complex translations. Remember that DP++ is not available on DisplayPort alternate mode over USB-C. So, if you are using USB-C you’ll need an active adapter to connect to the HDMI display. Final Words:I can understand conversion from DisplayPort to HDMI cables can be difficult. In such times, active adapters will help you to overcome these conversion problems. So, whenever you are confused between which types of adapter to choose, opt for an active adapter.
