USB Cable

For USB computer cable connections, there are two popular formats: USB 2.0 and the newer USB 3.0

How to tell USB 2.0 and 3.0 cables apart: 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 quite mind-blowing. For this computer cable guide, we have listed its more common uses below:

Connect one end to: 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 end to: USB ports on computer (see image below)

How to tell USB 2.0 and 3.0 ports apart: USB 2.0 ports have black tips while USB 3.0 ports come with blue tips. See image below:

USB 3.0 is backwards-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 , these are described as USB-A to Micro-B

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 is seen below but this can also be confused with Mini Display ports as they look identical and only visual difference is the picture beside the port. Thunderbolt 2 (left) has a lightning symbol and carries Data and video.

The Mini Display Port (right) will only carry Video.

And Thunderbolt 3 also known as USB-C on Apple Macs.

Display Port

Display port normally have symbol like this

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

Don’t Confuse HDMI port with Display port, they look very similar but are 2 entirely different Cables/Port.
