History and Development of USB Technology

History And Development of USB TechnologyWe certainly are familiar with USB technology, either on your computer or other technological devices, such as DVD Player, HiFi Compo, and so forth. From start to USB 1.0 to USB 2.0, we would've never tried it. In that sense the field of IT, its own USB stands for Universal Serial Bus, which with this technology we can connect many many peripherals and other devices into the computer.USB has the ability to plug 'n' play and also supports "hot swapping", where we can remove or install other devices through the connector without having to reboot. Another feature of the USB that we can get the power required is very small and we do not require additional power again.
USB early history began in 1996. In this, the USB version 1.0 was introduced. Some large companies are creating USB technology, among others, Intel, Compaq, Digital, IBM, and Northern Telecom, where each has its own role in creating the USB technology. As Intel by producing a UHCI host controller and open software stack, Microsoft produced a USB software stack for Windows and with National Semiconductor and Compaq participate formulate OHCI host controller. Philips-did not want to miss, they produced the first USB Audio.

Next is the USB version 2.0, which was launched in April 2000 and the use of standard USB-IF (Implementers Forum) at the end of 2001. Some large companies join to develop USB 2.0, USB 2.0 and eventually it has the capability of data transfer rate of up to 480 Mbit / s, far compared with USB 1.0 which only has a data transfer rate of 12 Mbit / s. Some large companies that developed the USB 2.0 is Hewlett-Packard, Intel, Lucent (now LSI Corporation), Microsoft, NEC, and Philips.USB 2.0
Even the more advanced-technology, USB 3.0 was introduced in September 2007. In version 3.0, data transfer rate could rise sharply up to 10 times more than previous versions. Then, USB 3.0 is referred to as SuperSpeed USB. Uniquely, a USB 3.0 also supports earlier versions, with the sense that the connector can also be used for USB 2.0, which is known by the name of backward compability.
USB 3.0Until now, the USB version 3.0 is the most advanced USB technology.
