Data cables are an important part of a computer, as they provide a connection between various hardware components. This enables a computer to communicate with its own various parts. A data cable also enables a computer to communicate with additional computers. A data cable is, essentially, any type of media capable of carrying a binary electrical communication signal. A data cable allows communication between hardware components within a computer & between multiple computers across a network. Peripherals, such as printers and scanners and cameras, are also connected via a data cable.
