Computer memory devices

External memory

• The main function of the computer's external memory is the ability to store a large amount of information (programs, documents, audio and video clips, etc.) for a long time.
• A device that records / reads information is called a drive or drive, and information is stored on media (for example, floppy disks).
• In floppy disk drives (floppy disks or floppy disks) and hard disk drives (hard disk drives or hard drives), the recording, storage and reading of information is based on the magnetic principle, and in laser drives - the optical principle.
