. "Universal Serial Bus (USB) is a specification to establish communication between devices and a host controller (usually a personal computer), developed and invented by Ajay Bhatt, while working for Intel. USB has effectively replaced a variety of interfaces such as serial and parallel ports. USB can connect computer peripherals such as mice, keyboards, digital cameras, printers, personal media players, flash drives, Network Adapters, and external hard drives. For many of those devices, USB has become the standard connection method. USB was designed for personal computers, but it has become commonplace on other devices such as smartphones, PDAs and video game consoles, and as a power cord. As of 2008, there are about 2 billion USB devices sold per year, and approximately 6 billion total sold to date. Unlike the older connection standards RS-232 or Parallel port, USB connectors also supply electric power, so many devices connected by USB do not need a power source of their own."@en . .

A single USB port can be used to connect up to 127 peripheral devices, such as mice, modems, and keyboards. USB also supports Plug-and-Play installation and hotplugging. Starting in 1996, a few computer manufacturers started including USB support in their new machines. It wasn't until the release of the best-selling iMac in 1998 that USB became widespread. But, while it was expected to completely replace serial and Parallel Ports, they still remain on motherboards."@en . . "The Universal Serial Bus (USB) is"@en . . "Commonly used to hook up most types of periprials to computers, such as printers, mice, keyboards, MP3 players, etc. Each plug has four wires, two power and two data. Most modern computers have at least 2, many have 4, also most modern motherboards have them built in and run them through the Northbridge interface."@en . "The Universal Serial Bus (USB) is"@en . . .
