- 1. Name: Ma. Rinamae Joy C. Paghubasan Date: July 21, 2014 Professor: Mrs. Fe Yara Subject: CS 111L Activity # 5 Storage Devices Task: Browse in the internet the different latest storage devices and it’s storage capacity. 1.) Name of Storage Devices Image of the Storage Description Use (what device?) Floppy Disk The smallest and most portable of all the storage devices usually holds about 1.44 MB of storage. Use a floppy disk media. Floppy disk is a small removable storage medium that records data on thin magnetic films. Data is read or written on them from the floppy disk drives. Floppy disks have, however, been replaced by memory cards, USB flash and external hard disk memory, which have a greater storage capacity. Super Drive The LS120 or SuperDisk is a drive which supports a special floppy diskette which can store up to 120MB or 240MB of information as well as being backwards compatible and still supporting the standard floppy diskettes. A trademark used by Apple Inc. for two different storage drives: from 1988–99 to refer to a high-density floppy diskdrive capable of reading all major 3.5" disk formats; and from 2001 onwards to refer to a CD/DVD reader/writer. Zip Drive New generation similar to the floppy disk drive created by Iomega The Iomega Zip Drive was first released 1994 and today is becoming a popular solution for PC and Macintosh computers as a A high-capacity floppy disk drive developed by Iomega Corporation. Zip disks are slightly larger than conventional floppy disks, and about twice as thick. They can hold 100 or 250 MB of data.

Zip Drives Disks come in100MB, 250MB and 750MB Because they're relatively inexpensive and durable, they have become a popular media for backing up hard disks and for transporting large files. CD Burner An optical storage device that holds data anywhere from 650MB to 700MB (74-80 minutes) A CD burner is the informal name for a CD recorder, a device that can record data to a compact disc. DVD Burner A newer optical storage device that holds data anywhere from4.70- 17.08GB A DVD burner is a device used to encode or "burn" information onto a blank DVD. A DVD is a form of storage media, 12 cm (4.72 inches) or 8 cm (3.15 inches) across, that can typically hold 4.7 gigabytes (GB) of information. 2.) Storage Term Approx.
