2. 3.5-INCH FLOPPY DISK
A floppy disk is a disk storage medium
composed of a disk of thin and flexible
magnetic storage medium, sealed in a
rectangular plastic carrier lined with fabric
that removes dust particles. They are read
and written by a floppy disk drive (FDD).

3. ZIP DISK
The Zip drive is a medium-capacity
removable disk storage system that was
introduced by Iomega in late 1994.
Originally, Zip disks launched with
capacities of 100 MB, but later versions
increased this to first 250 MB and then
750 MB.

4. MINI CD
Mini CD-R, Mini CD-RW: As of 2007, many
manufacturers offer 80 mm CD-R and CD-RW
discs for sale in retail electronics and office
supply stores. These are sometimes marketed
as "Pocket CD-R/CD-RW" (Memorex) or "Mini
CD-R" (TDK). Most of the blank discs available
in retail hold either 185 MB (21 minutes) or
210 MB (24 minutes) of data. The mini discs,
despite having less weight and plastic, are
generally more expensive than full size CD-
R/CD-RW discs.

5. TAPE DRIVE
A tape drive is a data storage device that
reads and performs digital recording, writes
data on a magnetic tape. Magnetic tape
data storage is typically used for offline,
archival data storage. Tape media generally
has a favorable unit cost and long archival
stability.

6. CD-R
A CD-ROM ( /ˌ rɒm/,
siˌˌdiˌˌ an acronym
of "Compact Disc Read-only memory") is a
pre-pressed compact disc that contains data
accessible to, but not writable by, a
computer for data storage and music
playback. The 1985 “Yellow Book” standard
developed by Sony and Philips adapted the
format to hold any form of binary data.[2]

7. CD-RW
A CD-RW (Compact Disc-Re Writable) is a
rewritable optical disc. It was introduced in
1997, and was known as "CD-Writable"
during development. It was preceded by the
CD-MO, which was never commercially
released

8. DVD-RW
A DVD-RW disc is a rewritable optical disc
with equal storage capacity to a DVD-R,
typically 4.7 GB. The format was developed
by Pioneer in November 1999 and has been
approved by the DVD Forum. The smaller
Mini DVD-RW holds 1.46 GB, with a
diameter of 8 cm.

9. MINI DVD
Mini DVD (Mini DVD or mini DVD) is a
DVD disc having 8 cm in diameter.
The 8 cm optical disc format was originally
used for music CD singles, hence the
commonly used names CD single and mini -
CD. Similarly, the manufactured 8 cm DVDs
were originally used for music videos and as
such became known as DVD single.

10. FLASH MEMORIES

11. MEMORY PEN (usb mass
storage)
USB flash drive is a data storage
device that includes flash memory with
an integrated Universal Serial Bus
(USB) interface. USB flash drives are
typically removable and rewritable, and
physically much smaller than a floppy
disk.

12. SECURE DIGITAL
Secure Digital (SD) is a non-volatile
memory card format developed by the SD
Card Association (SDA) for use in portable
devices. The SD technology is used by
more than 400 brands across dozens of
product categories and more than 8,000
models.

13. TRANS FLASH OR MICRO SD

14. MULTIMEDIA CARD
The MultiMediaCard (MMC) is a flash
memory memory card standard. Unveiled in
1997 by SanDisk and Siemens AG, it is
based on Toshiba's NAND-based flash
memory, and is therefore much smaller than
earlier systems based on Intel NOR-based
memory such as CompactFlash.

15. SECURE DIGITAL
Secure Digital (SD) is a non-volatile
memory card format developed by the SD
Card Association (SDA) for use in portable
devices. The SD technology is used by
more than 400 brands across dozens of
product categories and more than 8,000
models.

16. FLASH MEMORIES
Flash memory is a non-volatile computer
storage chip that can be electrically erased
and reprogrammed. It was developed from
EEPROM (electrically erasable
programmable read-only memory) and must
be erased in fairly large blocks before these
can be rewritten with new data
