Storage Devices

Storage devices can store digital information/data and applications (in the form of audio, video, image, etc.) to process the result of any computational work. They are a kind of computer hardware that stores information and instruction to be processed. A storage unit is a part of a computer system. Every computer has a storage device. The storage devices work as a memory. They are also known as a storage medium, digital storage, or storage media, which temporarily or permanently store information. They are used either internally or externally in the computer system, server, or any computation device to hold the information. Examples include a pen drive, CD, DVD, floppy disk, memory card and so forth.
