Invention of USB (Universal Serial Bus)

A bus is a communication pathway in a digital computer that allows data to flow between the central processing unit (CPU) and its memory and between among the CPU and peripheral devices. The bus played a key role in the development of the modern desktop computer in the later 1970s and 1980s.

It was developed and invented by Ajay Bhatt while working for Intel. He won the prize together with his team consisting of BalaCadambi, Jeff Morriss, Shelagh Callahan and Shaun Knoll for inventing the USB technology.

Frustrated with process of reconfiguring and rebooting the computer while installing a printer for his wife’s computer, Bhatt decided to create a connection interface that would recognize and run new devices automatically when they were plugged into computer.

USB is intended to replace many varieties of serial and parallel ports. The first silicon for USB was made available by Intel in 1995. The aim was to bring serial-port and serial bus technology into the twenty first century.

The USB 1.0 specification was introduced in January 1996. The original USB 1.0 specification had a data transfer rate of 12 Mbit/s. The first widely used version of USB was 1.1, which was released in September 1998.

The USB 2.0 was released in April 2000, and was standardized by the USB-IF at the end of 2001, was widely accepted by HP, Intel.
