USB 2.0

USB 2.0 is a standard for connecting devices like flash drives, keyboards, and printers to computers. It allows for data transfer between devices and the computer at speeds up to 480 megabits per second. USB 2.0 is widely used because it is reliable, compatible with many devices, and easy to plug in. It also provides power to connected devices, so some gadgets can operate without external power sources. While newer standards like USB 3.0 offer faster speeds, USB 2.0 remains common due to its broad compatibility and sufficient performance for many uses.
