                                                        ANSWER:

1.Storage device refers to the apparatus for recording computer data. Examples are the RAM, floppy drives, ZIP drives, and other disks drives. While, storage media are the materials on which data are written and stored. Examples are the floppy disks, optical discs, hard disks, etc.

2. Tape- hanging posters, decorative book cover, fix broken tail light on vehicle, twist a long piece into rope (thousands more uses), tape wires down on floor or out of the way,  tape wires back together after splicing (much wider than electricians' tape), reattach rear view mirror, repair cracked windshield/window, patch ripped clothing, hide unsightly wallpaper seams.

Magnetic Stripe Cards- an effective form of information storage.

Smart Cards- is a portable computational device with data storage ability, very reliable form of personal identification and a tamper-proof, secure information repository.

Microfilm- Because of its large storage capacity, microfilm was mainly used for archival purposes.

Microfiche- It is primarily used for high-capacity storage. The function has now been replaced by digital imaging and storage, but there are still data being archived as microfiche and huge archives of data that have not been transfered to digital storage systems.

Enterprise Storage- is a centralized repository for business information that provides common data management and protection, as well as data sharing functions, through connections to numerous (and possibly dissimilar) computer systems.

3.Solid State Drive- is an electrical term that refers to electronic circuitry that is built entirely out of semiconductors.

Memory Card- is an electronic flash memory data storage device used for storing digital information.

USB Flash drive- is a small device that stores information and files from a computer.

Express Card Modules- can provide the quickest way to download pictures from today's high-capacity digital camera cards (CompactFlash, MMC, MemoryStick, SD, xD, etc.).

4.CDs- an optical disc used to store digital data.

Archive Disc- 

Picture CD- holds photos from a single roll of color film, stored at 1024×1536 resolution using JPEG compression.

DVDs- offer higher storage capacity than compact disc while having the same dimensions.

Blu- ray disc- is an optical disc storage medium designed to supersede the DVD format.

5. Ink-jet Printer- create text and images by small nozzles spraying ink onto printer paper. The ink absorbs into the paper at different amounts and levels of crispness depending on the paper and ink quality. 

Photo Printer -it is able to run on battery power, it is versatile as to photo size, it has good consumer reviews, it has good specifications.

Laser Printers- speed, memory, resolution, duplexing, all in one printer, media support, consumables.
