  4. What are some of the uses of USB? USB is intended to replace many varieties of serial and parallel ports. USB can connect computer peripherals such as mice, keyboards, digital cameras, printers, personal media players, flash drives, and external hard drives. For many of those devices, USB has become the standard connection method. USB was designed for personal computers, but it has become commonplace on other devices such as smartphones, PDAs and video game consoles, and as a power cord. As of 2008, there are about 2 billion USB devices sold per year, and approximately 6 billion total sold to date.

  5. Some History on USB. USB began development in 1994 by a group of seven companies: Compaq, DEC, IBM, Intel, Microsoft, NEC and Nortel. The USB 1.0 specification was introduced in January 1996. The original USB 1.0 specification had a data transfer rate of just 12 Mbit/s. The first widely used version of USB was 1.1, which was released in September 1998. 1.1 had a transfer speed of 12 Mbit/s. The USB 2.0 specification was released in April 2000 and was standardized by the USB-IF at the end of 2001. USB has a higher data transfer rate, with the resulting specification achieving 480 Mbit/s, a fortyfold increase over 12 Mbit/s for the original USB 1.0.
