USB (Universal Serial Bus)
USB was
introduced in January 1996. The idea was to standardize the connectivity of the
devices. Also these devices were not plug-and-play devices. It was actually the
brain child of seven different companies-Microsoft, IBM, Intel, Compaq, Nortel,
DEC and NEC. The data transfer rate was also high as compared to the other
ports. For USB 1.0 it was 1.5 Mb/s, referred to as low speed, and 12 Mb/s as
full speed. Later in April 200, USB 2.0 was released with a maximum high speed
data transfer of 480 Mb/s. now in 2008 USB 3.0 was also launched with a maximum
transfer rate of 5 Gb/s. there is no doubt that USB has change the way we
connect our devices to computer.
