Nearly everyone with a computer has heard of a USB port. USB or Universal Serial Bus is a connector port that can be found on the front or rear of most PCs. This port allows users to connect peripherals quickly and easily. To help further understand USB we have developed this comprehensive tip:

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. The standard is being supported by many leading suppliers of computers and peripherals. An attractive advantage of USB is devices are hot pluggable (live connection/disconnection without data loss or interruption). Cables and devices manufactured to the current USB Revision 2.0 specification are backward compatible with version 1.1, but the reverse scenario does not apply.

The USB specification requires a host system to be equipped with an A type jack. The B type jack is typically found on peripheral devices requiring detachable cables. Therefore, detachable USB cables are configured as an A to B male combination which prevents improper bus configurations and topology miswiring.

USB is a serial, bi-directional bus that can be layered in tiers or star shaped with the use of a hub. USB does not require terminators or manual addressing.
