Output 1:

Output 1 Description of Output 1 This is another type of computer printer that creates an image on paper by propelling variable-sized ink droplets on paper to form text and graphics. They can produce finer, smoother detail through higher print head resolution. They are also have practically no warm up time and can print pages at a lower cost per page than laser printers. However, ink costs can be extremely high and life of a inkjet printer is limited. Also the nozzles can become clogged which can waste ink. Images of Output 1

Storage 1 Description of Storage 1 Magnetic tape is a medium for magnetic recording, made of a thin magnetizable coating on a long, narrow strip of plastic. Devices that record and play back audio and video using magnetic tape are tape recorders and video tape recorders . A device that stores computer data on magnetic tape is a tape drive. Magnetic tape revolutionized broadcast and recording it allowed recordings in multiple parts, which mixed and edited with tolerable loss in quality. Images of Storage 1
