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.
