1. Differentiate between storage devices and storage media.
Storage device is a hardware device capable of storing information. Storage media is any technology (including devices and materials) used to place, keep, and retrieve data. 2. Identify the uses of tape, magnetic stripe cards, smart cards, microfilm and microfiche, and enterprise storage.
A tape drive is a data storage device that reads and writes data on a magnetic tape. It is typically used for offline, archival data storage.
A magnetic stripe card is a type of card capable of storing data by modifying the magnetism of tiny iron-based magnetic particles on a band of magnetic material on the card.
A smart card, chip card, or integrated circuit card (ICC), is any pocket-sized card with embedded integrated circuits.
A smart card or microprocessor cards contain volatile memory and microprocessor components.
All microform images may be provided as positives or negatives, more often the latter.
Three formats are common: microfilm (reels), aperture cards and microfiche (flat sheets). Microcards, a format no longer produced, was similar to microfiche, but printed on cardboard rather than photographic film.
3. Describe the various types of flash memory storage: solid state drives, memory cards, USB flash drives, and ExpressCard modules.
A solid-state drive (SSD) is a data storage device that uses solid-state memory to store persistent data with the intention of providing access in the same manner of a traditional block i/o hard disk drive.
A memory card or flash card is an electronic flash memory data storage device used for storing digital information.
A USB flash drive consists of a flash memory data storage device integrated with a USB (Universal Serial Bus) interface.
ExpressCard is an interface to allow peripheral devices to be connected to a computer, usually a laptop computer.
4. Differentiate among various types of optical discs: CDs, archive discs and Picture CDs, DVDs, and Blu-ray Discs.
The Compact Disc (also known as a CD) is an optical disc used to store digital data.
Picture CD is a product by Kodak, following on from the earlier Photo CD product. It holds photos from a single roll of color film, stored at 1024×1536 resolution using JPEG compression.
DVD is an optical disc storage media format, invented and developed by Philips, Sony, Toshiba, and Panasonic in 1995. DVDs offer higher storage capacity than compact discs while having the same dimensions.
Blu-ray Disc (official abbreviation BD) is an optical disc storage medium designed to supersede the DVD format. The disc diameter is 120 mm and disc thickness 1.2 mm plastic optical disc, the same size as DVDs and CDs.
5. Summarize the characteristics of ink-jet printers, photo printers, laser printers, multifunction peripherals, thermal printers, mobile printers, label and postage printers, and plotters and large-format printers.
An inkjet printer is a type of computer printer that creates a digital image by propelling droplets of ink onto paper.
A laser printer is a common type of computer printer that rapidly produces high quality text and graphics on plain paper.
An MFP (Multi Function Product/ Printer/ Peripheral), multifunctional, all-in-one (AIO), or Multifunction Device (MFD), is an office machine which incorporates the functionality of multiple devices in one, so as to have a smaller footprint in a home or small business setting (the SOHO market segment), or to provide centralized document management/distribution/production in a large-office setting.
A thermal printer (or direct thermal printer) produces a printed image by selectively heating coated thermochromic paper, or thermal paper as it is commonly known, when the paper passes over the thermal print head. The coating turns black in the areas where it is heated, producing an image. Two-color direct thermal printers can print both black and an additional color (often red) by applying heat at two different temperatures.
