The universal serial USB has become the most used part of modern computers. It currently exists in two versions—1.0, which was the original standard for UBS. Then, 2.0, which is the superior version of the two. It was made for newer devices, and the difference between the two methods is in its speed.

USB 1.0 devices can only achieve a maximum speed of 12Mbps. 2.0 devices can go up to 40 times that at 480 Mbps. USB implementation did not provide an option for high-speed data transmission. Technical contraptions such as keyboards, the mouse, and game controllers generally only need a small amount of data to function correctly. USB 2.0 also adds the high-speed connection to the previous two, and it's at high speed that you can get the 480 Mbps.
