Cables

A wide variety of cables are used to connect peripheral devices to computer ports. For instance, you can use an Ethernet cable to connect the NIC port on a computer to a DSL modem device. Cables must possess the correct connectors to attach to the ports of the computer and the device and the correct internal wiring. Most of the time, when you purchase a specific type of peripheral for a computer, the correct cables come with the device. As a technician, however, you might have to replace damaged or missing cables, and you are responsible for understanding the different cable types and their appropriate use.

Audio Cables

The standard round jacks for line in, microphone in, and speaker out work fine for the majority of applications. However, an increasing number of people and businesses are moving to music, video, TV, and phone on PC. These applications demand a higher-quality sound output than the small underpowered speaker port can provide.
