USB

Universal Serial Bus (USB) is developed in mid-1990's that defines the cables, connection and communication between computers and electronic devices.
USB was basically designed to standardize the connections of computer peripherals such as keyboards, pointing devices etc. and other electronic devices and PDAs

History

A group of seven companies began the development of USB in 1994: Compaq, DEC, IBM, Intel, Microsoft, NEC, and Nortel.The goal was to make it fundamentally easier to connect external devices to PCs by replacing the multitude of connectors at the back of PCs, addressing the usability issues of existing interfaces, and simplifying software configuration of all devices connected to USB, as well as permitting greater data rates for external devices. A team including Ajay Bhatt worked on the standard at Intel. The first integrated circuits supporting USB were produced by Intel in 1995.
