USB Stand of Universal Serial Bus Which Invented to Facilitate Easier Connections Between Devices and Computers.

In 1996 USB 1.0 was introduced with a max. data transfer rate of 12Megabit/s. It had quite a few limitations. 

After 2 years in August 1998, USB 1.1 was introduced. 

in 2000 USB 2.0 was released. It is still used today. USB 2.0 is capable of data transfer of 480 Mbits/sec or 60MB/sec. 

In 2008, USB 3.0 was released. It was capable of data transfers upto 5Gbits/sec or 625MB/sec, was more power efficient and is backwards compatible with USB 2.0. USB 3.0 was termed as “SuperSpeed”. 

USB 3.0 ports look quite similar to USB 2.0 ports, but feature 9 pins instead of 4 found in 2.0. USB 3.0 operates in full-duplex mode, unlike USB 2.0 (half-duplex). This means, data upload and download can take place simultaneously without slowdown. When initially introduced, USB 3.0 didn’t see much mainstream support and industry biggies like Intel and Apple didn’t start USB 3.0 support until 2011.
