The principal function of a data cable is to transfer binary communication signals from source to destination. The binary data sent over data cables are a sequence of ones and zeros; they are usually in the form of electrical signals.
Data cables are a crucial part of any computing system because they facilitate communication between the different hardware components. Data cables, such as Ethernet cables, are used to transfer information between numerous computers in a network. Peripheral devices, such as cameras, scanners and printers, are also connected to a computer through a data cable. Data cables form the basis of guided transmission media. USB, SATA, Coaxial and IDE cables are all examples of data cables.
