History of USB

It is called Universal Serial Bus, but we all know it merely as USB. It is the interconnection standard for the transport of data – today also energy and video flows – which has been with us for over 20 years

The Universal Serial Bus (USB) standard officially debuted in 1996 – development started two years earlier – and is currently managed by the USB Implementers Forum (USB-IF). We actually owe it to a collection of seven companies: Compaq, DEC, IBM, Intel, Microsoft, NEC, and Nortel.

 The goal was to create a single connector to connect various external devices to the PC, obviously ensuring greater ease of use than previous solutions and higher speeds.

Ajay Bhatt(Intel designer), the person, has developed the USB standard.
