1. Differentiate between storage devices and storage media.

    A storage device is a hardware device capable of storing information. There are two storage devices used in computers; a primary storage device such as computer RAM and a secondary storage device such as a computer hard disk drive. In the picture to the right, is an example of a Drobo, an external secondary storage device.

    In computers, a storage media is any technology (including devices and materials) used to place, keep, and retrieve data. A medium is an element used in communicating a message; on a storage medium, the "messages" - in the form of data - are suspended for use when needed. The plural form of this term is storage media. Although the term storage includes both primary storage (memory), a storage medium.

2. Identify the uses of tape, magnetic stripe cards, smart cards, microfilm and microfiche, and enterprise storage.

• Tape, one of the first storage media used with mainframe computers, is a magnetically-coated ribbon of plastic capable of storing large amounts of data and information at low cost.
• A magnetic stripe card is a type of card capable of storing data by magnifying 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. Contains volatile memory card and microprocessor components. Made of plastic, generally polyvinyl chloride, but sometimes acrylonitrile but adiene styrene or polycarbonate.
• A microfilm and microfiche are publishing formats. They allow us to keep newspapers and other bulky publications in a compact, stable form.

3. Describe the various types of flash memory storage: solid state drives, memory cards, USB flash drives, and Express Card 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. SSDs are distinguished from traditional hard disk drives (HDDs), which are electromechanical devices containing spinning disks and movable read/write heads.
• A memory card or flash card is an electronic flash memory data storage device used for storing digital information. They are commonly used in many electronic devices, including digital cameras, mobile phones, laptop computers, MP3 players, and video game consoles.
• A USB flash drive consists of a flash memory data storage device integrated with a USB (Universal Serial Bus) interface. USB flash drives are typically removable and rewritable, and physically much smaller than a floppy disk Express Card is an interface to allow peripheral devices to be connected to a computer, usually a laptop computer. Formerly called NEWCARD, the Express Card standard specifies the design of slots built into the computer and of cards which can be inserted into Express Card slots. The cards contain electronic circuitry and connectors to which external devices can be connected. The Express Card standard replaces the PC Card (also known as PCMCIA) standards.
  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. It was originally developed to store and playback sound recordings exclusively, but later expanded to encompass data storage (CD-ROM), write-once audio and data storage (CD-R), rewritable media (CD-RW), Video Compact Discs (VCD), Super Video Compact Discs (SVCD), Photo CD, Picture CD, CD-i, and Enhanced CD. The product is aimed at consumers. Software to view and perform simple edits to images is included on the CD.DVD is an optical disc storage media format, invented and developed by Philips, Sony, Toshiba, and Panasonic in 1995.
  • 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. Blu-ray Discs contain 25 GB (23.31 GiB) per layer, with dual layer discs (50 GB), the norm for feature-length video discs.

  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. Inkjet printers are the most commonly used type of printer and range from small inexpensive consumer models to very large professional machines that can cost up to thousands of dollars.
    
  • 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.
  
  
  • 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 laser printer is a common type of computer printer that rapidly produces high quality text and graphics on plain paper. As with digital photocopiers and multifunction printers (MFPs), laser printers employ a xerographic printing process, but differ from analog photocopiers in that the image is produced by the direct scanning of a laser beam across the printer's photoreceptor.
