Universal Serial Bus (USB) is an industry standard developed in the mid-1990s that defines the cables, connectors and communications protocols used in a bus for connection, communication and power supply between computers and electronic devices.
USB was designed to standardize the connection of computer peripherals, such as keyboards, pointing devices, digital cameras, printers, portable media players, disk drives and network adapters to personal computers, both to communicate and to supply electric power. It has become commonplace on other devices, such as smartphones, PDAs and video game consoles. USB has effectively replaced a variety of earlier interfaces, such as serial and parallel ports, as well as separate power chargers for portable devices.
As of 2008, approximately 6 billion USB ports and interfaces were in the global marketplace, and about 2 billion were being sold each year.

Famous quotes containing the words bus, universal and/or serial:
“It seemed a long way from 143rd Street. Shaking hands with the Queen of England was a long way from being forced to sit in the colored section of the bus going into downtown Wilmington, North Carolina. Dancing with the Duke of Devonshire was a long way from not being allowed to bowl in Jefferson City, Missouri, because the white customers complained about it.”
—Althea Gibson (b. 1927)
“Universal suffrage should rest upon universal education. To this end, liberal and permanent provision should be made for the support of free schools by the State governments, and, if need be, supplemented by legitimate aid from national authority.”
—Rutherford Birchard Hayes (18221893)
“And the serial continues:
Pain, expiation, delight, more pain,
A frieze that lengthens continually, in the lucky way
Friezes do, and no plot is produced,
Nothing you could hang an identifying question on.”
—John Ashbery (b. 1927)
