In the previous post, we made mention of more than a few ports you may or may not have heard of and this time am going to be giving an overview of the most common computer cable types you’ll encounter when dealing with computers. And how they are connected to and to which port on a computer. The uses of almost all the ports in our previous post made mention of its required cables too and hence I won’t b explaining out how every cable works again but just widening your scope to show you that there are more cables out there than just your USB type-c cable. Especially when dealing with older versions of computers.

  1. VGA Cable

 

Also known as D-sub cable, analog video cable

For it to work, one end of the cable is connected  to the  computer monitor, television (PC input port) while the other end is connected to the VGA port on the computer

 

  1. DVI Cable

 

This cable is also made of 2 ends, one which needs to be connected  to the computer monitor and the other which needs to be connected to the DVI port on a computer

However, there are 2 types of DVI, DVI-I, and DVI-D.

DVI-D does not have the extra pins around the long pin, this is also a pure digital signal over DVI-I.

 

  1. HDMI Cable

 

one end to is connected to the computer monitor, television while the other to the HDMI port on a computer (see image below)

If you’re hooking up television to your computer, then we would recommend that you use an HDMI cable as your PC cable connection since it is able to transmit both display and sound – So you can not only use your TV screen as a monitor but also make use of your TV speakers to play PC audio.

 

  1. PS/2 Cable

 

one end should be connected to the PS/2 keyboard, PS/2 mouse and the other to the PS/2 ports on computer (see image below)

The one colored Purple is designated for the keyboard while the other which is colored Green is for the mouse

 

  1. Ethernet Cable

 

Also known as RJ-45 cable

Connect one end to the router, network switch while you Connect the other end to Ethernet port on a computer (see image below)

 

  1. 3.5mm Audio Cable

 

Also known as phone connector (since 3.5mm jacks are often found on mobile phones too)

To Connect this,  one end goes to computer speakers, 3.5mm headphones, 3.5mm microphone and the other Connects to the audio ports on computer (see image below use Green socket)

 

the Green audio port is designated for the computer speakers or headphones and the Pink audio port to the microphone

Blue audio port: MP3 player, CD player, DVD player, turntable, electric guitar, etc (line-in port to play and record sounds from the above devices)

  1. USB Cable

For USB computer cable connections, there are two popular formats: USB 2.0 and the newer USB 3.0 as mentioned in the ports post check it out here

To tell the difference from USB 2.0 and 3.0 cables, we look at the tips because USB 2.0 cables come with a black tip while the USB 3.0 cables have a blue tip, and sometimes you can find a SS “Super Speed” label on it. Since USB was intended to be the one computer cable connection to replace them all, it’s no surprise that the possible uses for a USB port are endless. jut its most common uses will be listed here

Connect one end to a USB device

 

Storage devices: USB flash drive, external hard drive, external optical drive

Input devices: USB keyboard (wired and wireless), USB mouse (wired and wireless), webcam, scanner, gamepad

Output devices: printer, all-in-one office machine, USB speaker

Wireless adapters: network (Wi-Fi) adapter, Bluetooth adapter, 3G adapter

Data (and charging) cable for mobile devices such as mobile phone, tablet, MP3 player

Connect other ends to USB ports on computer (see image below)

 

 

USB 3.0 is backward-compatible… meaning that you can connect a USB 2.0 device to a USB 3.0 port and vice versa but the USB 3.0 devices hooked up to a USB 2.0 port will perform at lowered rates. There are also USB cables which connect new external backup drives (see below), these are described as USB-A to Micro-B

 

  1. Computer Power Cord (Kettle Plug)

 

To connect, put one end at the AC power socket and put the other end at the power supply unit, a computer monitor. Always turn off your power supply unit (with the 1-0 switch at the back) before connecting a power cord to it.

 

  1. Thunderbolt/USB-C

 

Mostly seen on laptops and Apple Macs these cables are high speed and are capable of carrying data, video and other information. There are 2 current types of Thunderbolt, the older version Thunderbolt 2. But this is most at times be confused with Mini Display ports as they look identical and the only visual difference is the picture beside the port. Thunderbolt 2 has a lightning symbol and carries Data and video. The Mini Display Port will only carry Video.

 

  1. Display Port

 

Display Port is the best to use if you require a fast, high-resolution image. The cable has better quality over HDMI and is the best option if you have this interface.

And this makes up the list of we should all know. Put this guide to use when next your shopping for a new electronic device be it a Smartphone of A computer or an Audio set.
