- USB Drive
USB stands for Universal Serial Bus and is used to store date or transfer data from one computer to another. This IT technology was developed in mid of 1990s. When USB was first introduced, it was of large size and there was a power supply to give current to this IT technology.
In the most modern life there are many devices related with the computers but have different ways to connect with the computer. For example, printer is an external device and we need a wire for connecting it with the computer by wire. For that purpose, there is a connecter that is called serial port. Before this IT technology, serial port was used to connect the external components like, printers and plotters, etc.
