Universal Serial Bus (USB)

USB CableUniversal Serial Bus (USB) is a type of connector commonly used for asynchronous serial data transmission between a computer and attached devices.

A USB cable consists of a shielded casing containing two wires for power and earth, plus two wires for data transmission.

USB allows for the automatic detection of plugged in devices, and the automatic loading the device drivers if available.

USB has become the industry standard connection type and therefore widely available and used.  They are easy to work with as they cannot be connected incorrectly as the plug only fits in one way.

As the technology improves, newer versions of USB with faster transmission speeds are becoming available. New versions of USB are backward compatible with the older specifications.
