USB 3.0 is the third major version of the Universal Serial Bus (USB) standard for interfacing computers and electronic devices. Among other improvements, USB 3.0 adds the new transfer rate referred to as SuperSpeed USB (SS) that can transfer data at up to 5 Gbit/s (625 MB/s), which is about ten times as fast as the USB 2.0 standard.

1. INFINITE POSSIBILITIES!

2. 
 USB stands for Universal Serial Bus
 Provides an expandable, fast, bi-directional, low cost,
hot pluggable Plug and Play serial hardware
interface
 Allows users to connect a wide variety of peripherals
to a computer and have them automatically
configured and ready to use
 Implemented to provide a replacement for legacy
ports to make the addition of peripheral devices
quick and easy for the end user

A Brief History of USB
Creators, Goal

4. Who created USB ?
USB was created by USB Implementers Forum
(USB-IF) in 1996. And Developed and standardized by a group of leading companies from the
computer and electronics industries in 1995

5. 
 Unify— To replace the multitude of connectors at
the back of PCs
 Plug and Play—without the need for physical device
configuration, or user intervention in resolving
resource conflicts.
 Hot Swapping—allowing devices to be connected
and disconnected without rebooting the computer or
turning off the device.
