Dell Universal Serial Bus (USB)

USB is a type of input that allows you to connect a peripheral (such as mice, keyboards, pen drive, external hard drives...) to your computer or other devices.

Currently, we work with PCs that feature USB ports in 2.0, 3.1 and Type C models. Do you know the difference between different types of USB? We explain below.

What is the difference between USB 2.0 and USB 3.1?

What is the difference between USB 2.0 and USB 3.1?

Both model 2.0 and 3.1 have the same connection format, this means that you can use the same input for both types of USB.

But remember that, in order to have access to the full power of 3.1, it is necessary to connect it to an input of the same value.

Check out a summary below that shows the difference between USB 2.0 and 3.0.

USB Types

  1. USB 2.0

    The 2.0 model was created in the 2000s, which made this type of technology become popular. It is present in virtually all of our products.

    Speed: 480 Mb/s

    Time spent and transferred Mb : 10 minutes = 288,000 Mb

    What you can do with that time: Transfer 411 2-hour films (700 Mb average).

  2. USB 3.1

    As everything in technology is evolving, in 2009, version 3.0 was released and even more recently, in 2013, 3.1 with a much greater power than its predecessors.

    While USB 2.0 only allows you to send or receive data, version 3.1 makes it possible to do both activities at the same time.

    Speed: 5 Gb/s

    Time spent and Mb transferred : 10 minutes = 5,949,000 Mb

    What you can do with that time: Transfer 8,213 2-hour films (700 Mb average).

  3. USB Type–C

    The USB Type -C input is a technological innovation launched in 2014 and its main advantage is that it is symmetrical and reversible.

    Who has never been through this situation of trying to fit cables or pendrives or mice in one way, make a mistake, turn the input and then manage to connect? With USB Type -C, this problem is in the past.

    Turn it up or down, whatever: the connection will work anyway.

    In order to make everything smaller and more practical, it is more compact and can transfer files at high speed (up to 10Gb/s).
