What is USB?
We can determine USB (Universal Serial Bus) as a Plug & Play type interface (that is, it is activated by simply plugging it into the connector), which doesn’t need any type of controller. This type of interface allows users to cooperate with the PC using different devices like keyboards, mouse, printers, cameras, Pen drives, external hard disk, etc., with a good data transfer speed.
Another feature of USB ports is that they can control a large number of devices and peripherals with a single PC since you can maximize the number of USB ports through specialized HUBs.
USB 2.0 Features
The USB 2.0 standard, also known as Hi-Speed USB, was a breakthrough in the evolution of USB technology. It transfers data to about 60 MB/s, getting a great performance of the devices that use this technology, which can interact with the PC at an impressive speed.
Due to these characteristics, USB 2.0 technology has become a standard benchmark in today’s computing. Almost all communication devices of PCs are USB 2.0, among which we can highlight; keyboards, mouse, memories, disks and all kinds of multimedia devices.
The main drawback of USB 2.0 is that it lags behind certain data transfers in high definition, unable to support them, which is why the new USB 3.0 technology is born
USB 3.0 Features
Unlike USB 2.0, this new technology (USB 3.0 Super Speed) is almost ten times faster, as it transfers data to 600 MB/s. Also, we can note that it has support for external HD devices, which increases its performance.
Main differences between USB 2.0 and 3.0
- The main appreciable difference is the data transfer rate, which is much higher in the USB 3.0 standard.
- HD format support is almost nil in USB 2.0 but is widely supported by USB 3.0.
- USB 3.0 devices can be connected to USB 2.0 ports, but the reverse case is impossible.
- USB 2.0 devices are compatible with Windows XP, while USB 3.0 is not.
This is the difference between USB 2.0 and 3.0. Hope you like the post, share it with others also.
