Hello, Friends, are you know about USB 2.0/3/0/3.1? Lots of people confuse about Version, So I am going to tell you about the basic difference. Generally, when we have need of Pen drive then we go to market or online and buy any one brand of pen drive from there. But we do not consider the feature about Pen Drive that who will perform better on my PC. So I have listed the possibilities and feature.

What is USB?

USB stands for Univeral Serial Bus. It is the common interface which enables communication between a host controller and a device such as a PC. It connects many other devices such as mice, Cameras, Printers, Scanners and many other devices.

As of its variety of user’s including electrical power so Univeral Serial Bus has been replaced for a wide range like the serial port and parallel port. It stores all the data in the USB it makes as a pen drive.

The USB 2.0

Its standard is of type A its bandwidth is about 40MB/Second, it means it will data transfer 40 MB per second. its power is 2.5W as It is off less portable that is 2.0. its original cables are about 5m and it has no vision std.

it is also called hi-speed. It increased the data transfer for Computer to USB device to much speed of 480 Mbps, which is 40 times faster than the old version of USB that is the Version 1.1 specification.

In 2.0, it increased bandwidth and high throughout digital things. It also allowed for the multiple high-speed devices to run one by one. It increased stability and multi-channel audio support too.


The USB 3.0

Its standard types are of B. it is the third major version of the USB which stands for connectivity. Its bandwidth is about 400MB/second or much greater. Its power is about 4.5-7  W. its cable is about 3m. it has vision std of USB 3.0.

It has a new mode of transfer of super mode. The cable of transferring data is up to 5 bits. which is more than 8 times as fats nearly 475 Bit/s with high speed of USB 2.0. Besides different users, it has a new mode of transfer high portable space in it.


The USB 3.1

It is the latest feature. It has the standard type that is c . its bandwidth is about 5480 or much higher (not exact). Its power is about 5.9-8 W. its has vision std bout 4m. it has double peak speed than the old version. It refers to reversible connection type.

While the version number refers the data transfer speeds and other special features. Using these high current modes is fine, as the ports are all built around and in a convenient way.

Physical difference between 2.0, 3.0, 3.1

The major difference between 2.0, 3.1, 3.0 is the speed connectivity among them. The physical difference is the number of wire connections.  The new technology greatly improves but making use of it is less among them.

It result improves using but single bi-directional data pipe is used where data only flows in one direction. USB 2.0, 3.1, 3.0. overcomes key limitation of all specification all these limitations with the five to nine times higher bandwidth better error management higher power supply and cable and speed between them.

In this session, we learned the major difference between the USB 2.0, 3.1, 3.0. I hope, you will like this information. Thanks for Reading, Please share it.
