USB

What is USB?

Universal Serial Bus is a high speed connectivity standard enabling simple plug and play connections to devices such as modems, digital cameras, camcorders, keyboards and mice. An attractive advantage to USB is devices are hot pluggable (live connection/disconnection without data loss or interruption).

Cables and devices manufactured to the current USB version 2.0 specifications are backward compatible with version 1.1, but the reverse scenario does not apply.

What is the difference between a USB Type A and a USB type B connector?

Type A jacks are found on the host and hubs.
Type B jacks are found on peripherals.
