HDMI, DisplayPort, DVI, VGA, Thunderbolt - Video Port Comparison

hello everyone in this Article we're going to talk about the different video adapter ports now these ports are typically found in computers monitors TVs and various video equipment so the first one we're going to talk about is the VGA port which stands for video graphics array now this is an older port that's been around for a while in fact it's been around since 1987 the VGA port has 15 pins divided into three rows and it only carries analog data and because it only carries analog data the quality of the video may degrade at higher resolutions and longer cable lengths and the end adapter will typically have a blue color the VGA port was used on the now-extinct bulky CRT monitors but you can still find VGA ports on some new equipment such as new LCD monitors but as I stated before the VGA is an old design and is slowly being phased out in favour of more modern designs and the next video port is called DVI which stands for digital visual interface the DVI port has succeded the VGA port it was developed in 1999 and it was designed to provide uncompressed high-quality video to LCD monitors now there are three different versions of a DVI standard there's DVI a where the a stands for analog and this is used to send only analog signals there's DVID where the D stands for a digital and this is used to send only digital signals and is also a DVI I where the I stands per integrated now this is used to send both analog and digital signals now on the ports that are able to send digital signals which would be the DVI D and D VII there are two different options in the DVI standard there is single link in dual link now the difference is that dual link has six extra pins and these pins are what allows for a higher resolution than single link dual link DVI doubles the video bandwidth which has a max resolution of 2560 by 1600 whereas single-link DVI has a max resolution of 1920 by 1200 and the DVI end adapter will typically have a white color another type of video port is called HDMI which stands for a high-definition Multimedia Interface HDMI has a broad range of use in electronic products such as TVs monitors laptops mobile devices and so on it is in fact the dominant video port that is used today it was developed in 2002 and it was designed for transmitting uncompressed video and audio digital data through a single cable HDMI is one of the best standards for high-definition in consumer electronics delivering crystal-clear video as well as audio but in 2009 HDMI 1.4 was released and it added another channel to HDMI for data which has the capability of network communication so the connected devices that use this feature will give HDMI the ability to send and receive data at 100 megabits per second Ethernet so in addition to video and audio on a single cable the HDMI cable will have another ability of Ethernet networking but also with HDMI 1.4 it also added support for 4k video at 30 Hertz and in 2017 HDMI 2.1 was released which added support for a higher resolution and refresh rates with support for 4k video at 120 Hertz and 8k video at 60 Hertz and it can also support a max resolution of 10k commercial audio-visual systems and specialty usages and there's also the DisplayPort the DisplayPort debuted in 2006 and it was developed by Visa which stands for the video electronics standards Association the DisplayPort was primarily designed to be used for video but in addition to video it can also be used to carry USB and audio data as well it's a high-performance interface that is meant to replace the older VGA and DVI interfaces and it can also connect by using adapters to the older DVI VGA and HDMI ports one of the main advantages that it has over HDMI is that it has multi monitor capabilities the DisplayPort allows you to use multiple monitors by connecting them in a daisy-chain configuration so for example if you wanted to use three monitors on your computer you would connect a cable from the display port on your computer and the other end to the first monitor then the first monitor would connect directly to the second monitor and then the second monitor would connect to the third monitor so now you'll have three working monitors while using only one display port on your computer and this is why the DisplayPort is more focused for computer use than for other equipment such as televisions another advantage that DisplayPort has over HDMI is that it has a locking mechanism that keeps the cable locked in place whereas HDMI does not have a locking mechanism and also unlike hdmi displayport is a royalty-free product and in March of 2016 DisplayPort 1.4 was released which has a max resolution of 8k at 60 Hertz and the last part we're going to talk about is Thunderbolt Thunderbolt is a high speed technology interface that outputs one serial signal from a combination of PCI Express and the DisplayPort Thunderbolt is not just for connecting video but it's also used for attaching other external peripherals as well in fact it can daisy chain up to six devices Thunderbolt was released in 2011 and was mainly used in Apple products and now it has become available to pcs now there are three different versions of Thunderbolt versions 1 and 2 uses same connector as a mini DisplayPort and version 3 uses a USB type-c connector

BIOS, CMOS, UEFI - What's the difference?

what is the BIOS CMOS and UEFI so that's what we're going to talk about in this video now BIOS stands for basic input/output system the BIOS is firmware that's built into the motherboard that initializes the computer's hardware as the computer is being booted and then after it initializes the hardware it then searches for a boot device such as an optical drive or a storage drive to boot software such as an operating system so from the start when you first turn on the computer the computer does what's called a power-on self-test or post which is run by the bios it tests the computer to make sure all the requirements are met and if the hardware is working correctly before starting the operating system if the computer passes the test the internal speaker will make a short single beep which indicates that the computer has passed the test and is booting up normally however if there are no beeps or multiple beeps then that means that the computer has failed the test and s...

Printers Explained - Laser, Inkjet, Thermal, & Dot Matrix

hello everyone in this article we're going to talk about different types of printers now printers allow the ability to print copies of documents or photos onto paper from a computer now there are several different types of printers but the most common types that are used in homes and businesses are inkjet and laser printers and there are also a couple of less common printers such as thermal printers and dot matrix printers which we'll talk about later so let's first talk about inkjet printers now inkjet printers are the most common printers that are used in homes they are affordable and they produce photo quality results and they are enough to suit the needs of a typical home user now an inkjet printer works by the printhead moving back and forth across the paper during printing and during this process the printhead places ink on the paper in very tiny dots in fact these dots are so tiny that they are smaller in diameter than a human hair and as these dots are precisely pla...

Port Forwarding Explained

what is port forwarding now maybe you've heard about it but you weren't exactly sure what it was or how it works so basically port forwarding allows computers over the Internet to connect to a specific computer or service within a private network it's basically making your computer accessible over the Internet even though you're behind a router so for example let's say a friend of yours at their home wants to remotely control your computer at your home using a service such as remote desktop connection now remote desktop connection is a service built into Microsoft Windows that enables you to connect to another computer running Microsoft Windows and then once you're connected to the remote computer you can use that computers programs and files just as if you were sitting in front of it so now your friend is ready to connect to your computer so we starts up the remote desktop connection and sends the request to your public IP address with a specific port number no...
