Versions 1.0 and 1.1 have fallen out of use and are no longer used. Version 2.0, launched in the year 2000, is still present in many devices, but it is increasingly rare to see a device that has several USB ports does not include at least one USB 3.0 between them. The USB 3.0 standard is heading towards mass popularity, while versions 3.1 and 3.2 are still restricted to high-end products. – USB 3.2 – Transfer rate up to 10/20 Gbps (SuperSpeed +).– USB 3.1 – Transfer rate up to 10 Gbps (SuperSpeed +).This means that if it takes an hour to transfer some data to a USB2.0 device, it could take as little as 6 minutes using a USB3.0 device. – USB 3.0 – Transfer rate up to 5 Gbps (SuperSpeed) The main improvement is transfer speed: USB2.0 has a maximum speed of 480 mbps (megabits per second) Whereas USB3.0 is capable of a whopping 5 Gbits/s (5000 mbps), or a 10x speed increase.

– USB 2.0 – Transfer rate up to 480 Mbps (Hi-Speed).

– USB 1.1 – Transfer rate up to 12 Mbps (Full-Speed).

– USB 1.0 – Transfer rate up to 1.5 Mbps (Low-Speed).

The main difference between the versions is in the maximum transfer rate supported. When the first model appeared, in 1998, it supported only 1.5 Mbps. Just over 20 years later, current versions can reach up to 20 Gbps. Check the maximum transfer rate for each version. Today, in addition to mice and keyboards, monitors, printers, smartphones and several other types of devices take advantage of this input to make connections simpler.

This standard was created at the end of the years with the aim of making peripherals more easily connected to PCs. USB is an acronym for Universal Serial Bus. Know the differences between USB versions Also Read : How to Fix Unable to Complete Format on USB Flash Drive
