Write about different types of computer discs.
Types Of Computer Discs
HARD DRIVES
Hard drives are also known as ‘fixed disks’ because the data is stored in the memory of a computer and is not intended to be removed. It is comprised of one or more metal platters that are stacked together on a single spindle. Multiple read or write heads float next to the surface of the drive.
FLOPPY DRIVES
Floppy disks are designed to allow users to store data to a disk, remove it, and can be portable elsewhere.
CD-ROM
CD ROMs, also called as Compact Disk Read Only Memory, are shiny disks in the shape of a circle made of plastic with a hole in the middle. Data are stored on them. They are read using a powerful light-emitting diode that is sometimes called a ‘laser’ and thus it is known as a ‘laser disk’. It can store about 640 MB of data.
DVD-ROM
Digital Video Disks are first used to store movies and are also used for playback on compact players. It is still in use to store the data for movies and games.
Blu-Ray
Blu-Ray is the latest development in data storage and movie disks. It is called Blu-Ray because it uses a blue LED to read or write from the disk.
REMOVABLE DRIVES
These are drives that can be removed or ported elsewhere. The media is not pulled out; instead, it is removed.
