Cable

In today’s electronic age, cables have an ubiquitous existence. One can find a wide range of cables creeping behind a desktop computer and other electronic devices like televisions, music systems, etc. Although wireless technology has enabled communication between devices without using any wires, cables still have an edge over wireless technology as they offer reliable and consistent performance without external signal interference.

Usually, a cable has one, two or more wires bound together in a common protective jacket or sheath. The wires inside the sheath are protected by some insulating material. Cables generally use copper or aluminium wires as they are excellent conductors of electricity.

Cables are available in different varieties depending on the intended use. Some common cables include optical cables, crossover cables, Bowden cables, etc. Optical cables are generally used for commercial purposes, such as in telecommunication systems or in illumination tasks and imaging optics. These cables use optics technology and are made of plastic or glass. Special types of cables are largely used in computers. Combination cables can have both electrical wires and optical fibres. A crossover cable is used to interconnect two computers so as to enable direct communication. This cable is also used to connect Ethernet devices that facilitate seamless data transfer between routers in a network. Examples of cables include HDMI cable, Ethernet cable, network cable, audio cables, etc.
