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).

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.

MINI CDMini 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.

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.

CD-R

A CD-ROM ( /ˌsiːˌdiːˈrɒm/, 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]

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

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.

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.

FLASH MEMORIES

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.

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.

TRANS FLASH OR MICRO SD

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.

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.

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
