3.5-inch Diskette Diskette or floppy disk is thin and flat plastic sheet wrapped in plastic cover 3.5 inches.. The data and programs stored on floppy disks in the form of magnetic dots, according to the pattern of on / off standard and representative data (eg ASCII). The plastic wrap protects the diskette from the touch of human hands. Previously, larger disks and wrapped in paper so that it looks fragile. Currently, encased by a rigid plastic disk so it is quite flexible. Floppy disk can store 1.44 megabytes of data, equivalent to writing as many as 400 pages.

Hardisk hard disk or hard disk drive abbreviated HDD or hard drive abbreviated HD is a component of hardware that stores data containing the secondary and disk magnetic. Hard disc was first invented by engineer IBM, Reynold Johnson di tahun IBM, Reynold Johnson in The first hard disk is composed of 50 disks measuring 2 feet (0.6 meters) with the rotational speed reaches 1200 rpm (rotation per minute) with a storage capacity of 4.4 MB. Hard disks today there are only 0.6 cm wide with a capacity of 750 GB.HDDHD hardwaredatamagneticengineerIBM1956IBM1956rpmMB GB

Removeble Hard Drive Is a compact disc of this type of optical disk (optical disc) that can store data.compact discoptical disk divided Into 2: CD-ROM CD-ROM stands for compact disk read only memory, which means bahhwa CD-ROM drives can only be used to read a CD only. In large gari CD-ROM is divided into two according to its type, namely: ATA / IDE and SCSI. Yang. Which underlies most of that difference is speed.

DVD-ROM Dvd rom is the drive that can read the piece cd and dvd is also able to read the pieces in the form of dvd-rom, dvd movie, dvd audio, etc.. But it can only read it almost all types of cd and dvd but dvd ram, which usually require a dvd-rw drive.

Tape Drive Tape Drive is the secondary storage device can be evaluated on the basis of capacity, speed and scalability of data transfers it.

Pocket-Size Drive USB flash drives are flash memory data storage devices integrated with a USB (Universal Serial Bus) interface. USB flash drives are usually removable and rewritable, and physically much smaller than a floppy disk. Most weigh less than 30 g (1 oz).

Microdrive The Microdrive is a brabd name for a miniature, 1-incih hard disk designed to fit into slots (CF), CompactFlaseh type II.
