Why are USBs useful?

T he USB -its full form is Universal Serial Bus- is a connection used to connect a computer to devices such as digital cameras, printers, scanners, and external hard drives.

It was developed in 1994 by a group of seven companies. They were Compaq, DEC, IBM, Intel, Microsoft, NEC, and Nortel. Like a hard disk, a USB drive- or flash drive as it is popularly known stores information.

However, with a flash drive you can easily transfer that information from one computer to another. USB flash drives vary in size and shape and can hold gigabytes of information. USB flash drives are also called pen drives, key chain drives, key drives, and memory keys.

When it comes to saving important digital files, the importance of a USB drive can’t be stressed enough.

USB flash drives are not a new invention, but as the world becomes more and more digital, the need for these devices is growing rapidly.
