USB 2.0
Definition :
(Universal Serial Bus High Speed) is the next generation of Universal Serial Bus and is 40X faster than
USB 1.1 with a transfer rate of 480 Mbps.
History :
The USB 2.0 hardware standard was announced in 2000 but the hardware finally rolled out in 2003 in
the market. In context of data transfer bandwitdth, It showed a huge improvement of about 30 times in
comparison to USB 1.0 (30 MBps versus 1 MBps).
Nowadays , flash drives follow the USB 2.0 standards , but due to technical limitations in the basic flash
technology they dont support the full 60 MBps bandwidth as specified in the USB 2.0 standards.
Uses :
It is an external serial interface. The most widespread use of this interface has been made to transfer data
etween a computer and other devices such as thumbdrives , Mobile phones , digital cameras , hard disks
etc.
Another use of this interface is being made by input/output devices such as mouse , keyboard , printers ,
scanners , wifi dongles etc .
Advantages :
It is a plug n play interface. This means that the computer does not need to be powered off in order to
plug in or unplug a USB 2.0 component
USB 2.0 allows all sorts of new and improved USB devices to be added to the USB product lineup such
as fast disk drives, CDRW's, High Quality Video Cameras, and High Speed Scanners.
Disadvantages :
USB 2.0 has much higher speeds than USB 1.1. But many people end up inadvertently running devices in
a lower-speed compatibility mode as they are not compatible with newer version.
USB 3.0
Definition :
USB 3.0 is called "SuperSpeed USB 3.0,". It gives a 10 times increase in bandwidth from 480 Mbps to
4.8 Gbps . It also reduces the use of CPU cycles by not checking continously the state of a device or an
application to infer if it wants to communicate or is connected to the system.

History :
USB 3.0 was launched in 2008.
In September of 2007 , Pat Gelsinger from Intel announced the development of USB 3.0 as a successor to
USB 2.0 standard at the Intel Developer Forum . In January 2008 at CES , the physical connectors for
this standard were presented.
During the early days , it was speculated that this standard will have an optical fiber link in addition to the
four copper wires present in all the former USB standards. Though it never made it to the actual standards
and was replaced by a copper wire . Also , it allows backward compatibility.
Uses :
It gives a tremendous boost in data bandwidth which is of much use in external hard disks , HD cameras ,
thumbdrives etc .
Advantages :
It supports transfer rates of upto 4.8 GBPS which is 10 times higher than USB 2.0 and around 6 times
higher than firewire 800 .
