USB: Universal Serial Bus

As we all know, USB stands for Universal Serial Bus. It is an industry standard that was developed to define cables, connectors, and protocols for connection, communication, and power supply between personal computers and their peripheral devices. USB standards were first released in 1996 and are maintained by the USB Implementers Forum, which is a non-profit organization created to promote and support USB – Universal Serial Bus. USB 0.8, 0.9, and 0.99 were released in December 1994 and mid-1995, and they were somewhat prereleases. Going from 5V 1.5 A max power in USB 1.0 to 20V 5A Max power in USB 3.0 version 1.1, we have progressed a lot.

Currently, there are three generations of USB Specifications:

USB is further divided into various types, depending on the shape and size of the connector.

Type A

  1. associated pictures to accompany would be welcome. USB-C is still not too common even in new smart phones – at least where I come from so the USB mini is not really just in the older smart phones
