.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.
.tape- refers to a strip of long, thin and narrow matter, usually rolled up.Use for recording media.
.magnetic stripe cards-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. The magnetic stripe, sometimes called swipe card or magstripe, is read by physical contact and swiping past a magnetic reading head.
.smart cards-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. The card is made of plastic, generally polyvinyl chloride, but sometimes acrylonitrile butadiene styrene orpolycarbonate . Smart cards may also provide strong security authentication for single sign-on (SSO) within large organizations.
.microfilm and microfiche-are publishing formats. They allow us to keep newspapers and other bulky publications in a compact, stable form. The publisher photographs the pages of a work (usually newspapers, magazines or journals) in miniature, and places them on card-shaped photographic material (microfiche) or strips of film on reels(microfilm).Most of the microfilm and microfiche in the library is kept on Lobby Level or Level Two, in the Periodicals Room. There are some items on microfiche in Government Documents. To read it, use a microfiche or microfilm reader. To copy pages, use a reader-printer and card in the same area of the Periodicals Room. If you need help with microfilm or microfiche, ask at the service desk or at the Reference Desk.
.enterprise storage-is the computer storage designed for large-scale, high-technology environments of the modern enterprises. When comparing to the consumer storage, it has higher scalability, higher reliability, better fault tolerance, and much higher initial price.
3. Describe the various types of flash memory storage: solid state drives, memory cards, USB flash drives, and ExpressCard modules.
.solid state drives- (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. SSDs, in contrast, use microchips which retain data in non-volatile memory chips and contain no moving parts. Compared to electromechanical HDDs, SSDs are typically less susceptible to physical shock, are silent, and have lower access time and latency, but are more expensive per gigabyte (GB) and typically support a limited number of writes over the life of the device. SSDs use the same interface as hard disk drives, thus easily replacing them in most applications.
. memory cards- 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. They are small, re-recordable, and able to retain data without power.
.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. Most weigh less than 30 g (1 oz). Storage capacities in 2010 can be as large as 256 GB with steady improvements in size and price per capacity expected. Some allow 1 million write or erase cycles and offer a 10-year shelf storage time.USB flash drives are often used for the same purposes for which floppy disks or CD-ROMs were used. They are smaller, faster, have thousands of times more capacity, and are more durable and reliable because of their lack of moving parts. Until approximately 2005, most desktop and laptop computers were supplied with floppy disk drives, but floppy disk drives have been abandoned in favor of USB ports.USB Flash drives use the USB mass storage standard, supported natively by modern operating systems such as Linux, Mac OS X, Windows, and other Unix-likesystems. USB drives with USB 2.0 support can store more data and transfer faster than a much larger optical disc drives like CD-RW or DVD-RW drives and can be read by many other systems such as the Xbox 360, PlayStation 3, DVD players and in some upcoming mobile smartphones.
.ExpressCards Modules-is a new technology that slots into a computer system to allow the addition of hardware capabilities. The Expresscard was introduced by the Personal ComputerMemory Card International Association (PCMCIA) in 2003 and is a thinner, lighter and faster modular expansion for users of desktop and notebook computers. Hardware capabilities such as extra memory, wired and wireless communication tools and security devices can be added by inserting these modules into the system.The Expresscard module comes in two sizes. The Expresscard/34 is 34 mm wide, while theExpresscard/54 is 54 mm wide. The modules are both 5 mm high and 75 mm long. The 34 mm module has the advantage in that it can fit into the slot designed for the 54 mm card, but not vice versa. The Expresscard simply slots into a USB interface that is already integrated on most desktop computers and notebooks.
4.Differentiate among various types of optical discs: CDs, archive discs and Picture CDs, DVDs, and Blu-ray Discs.
.CDs-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), PhotoCD, PictureCD, CD-i, and Enhanced CD. Audio CDs and audio CD players have been commercially available since October 1982.
.archieve discs and picture CDs- is an archive file (also known as a disc image) of an optical disc, composed of the data contents of every written sector of an optical disc, including the optical disc file system. ISO images can be created from optical discs, or can be used to recreate optical discs using software from many software vendors. ISO image files typically have a file extension of .iso. The name ISO is taken from the ISO 9660 file system used with CD-ROM media, but an ISO image might also contain a UDF (ISO/IEC 13346) file system.
.DVDs-is an optical disc storage media format, invented and developed by Philips, Sony, Toshiba, and Panasonic in 1995. DVDs offer higher storage capacity thancompact discs while having the same dimensions.
.blue-ray discs-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. Triple layer discs (100 GB) and quadruple layers (128 GB) are available for BD-XL Blu-ray re-writer drives. Currently movie production companies have not utilized the triple or quadruple layer discs, most consumer owned Blu-ray players will not be able to read the additional layers, while newer Blu-ray players may require a firmware update to play the triple and quadruple sized 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:
.ink-jet printers-. 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. 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.The concept of inkjet printing originated in the 19th century, and the technology was first extensively developed in the early 1950s. Starting in the late 1970s inkjet printers that could reproduce digital images generated by computers were developed, mainly by Epson, Hewlett-Packard (HP), and Canon. In the worldwide consumer market, four manufacturers account for the majority of inkjet printer sales: Canon, HP, Epson, and Lexmark, a 1991 spin-off from IBM.The emerging ink jet material deposition market also uses inkjet technologies, typically printheads using piezoelectric crystals, to deposit materials directly on substrates.
.photo printers-allow us to recreate some of our most precious memories. Our digital pictures capture loved ones in unforgettable moments so it's obvious they're important to us. Fortunately some of the world's biggest names in printing and photography have developed a series of Photo Printers that are able to print images with superb color vibrancy and intricate detail. Companies like Epson, Canon, HP and others continue to come up with new ways to have our digital pictures "jump off the paper" at us with their latest photo printers.
.laser printers- is a common type of computer printer that rapidly produces high quality text and graphics on plain paper. As with digital photocopiers andmultifunction 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.
.multifunction peripherals- 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 typical MFP may act as a combination of some or all of the following devices:
.thermal printers-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.
.mobile printers-For printing on the run—or in really tight spaces— a mobile printer fits the bill. It's small, lightweight, and preferably battery-powered. All other considerations are secondary.
The largest mobile printer available is 6.5 by 13.3 by 3.2 inches (HWD). The smallest is 2.0 by 11.9 by 4.4 inches. You could fit both into one large shoebox. The heaviest is 4.6 pounds, the lightest 2.1 pounds; even together, they weigh less than some notebook computers. For most, batteries are either standard or available as an option. (Make sure the quoted price includes a battery if you want one.) They are also remarkably similar in price, with a range of $250 to $350.
. label and postage printers-- A preprinted mailing label that includes the machine readable codes per USPS specs allows getting free delivery confirmation on some mail services. This can be done using the software tools supplied by eBay or PayPal for example at no charge. But this requires getting the address information into your computer. For a small operation that means hand typing, but for large operations they may have order procession software that prints the all the shipping doucments.
- When using metered postage you can ship items weighing over 1 pound which you would otherwise need to take to the post office. This is because the USPS has confidence in the accuracy of the scales used by the mailing systems. This can save trips to the post office and which is expensive both in terms of time and also gasoline.
- It's much more convient and time saving to place a single preprinted stamp on a parcel than to put on 3 different value stamps.
- Cleaner appearance. Using a preprinted stamp looks better than a bunch of stamps.
- Advertizing can be done using the photo stamps, but at a price. A lower cost alternative would be to use an ink pad type stamp and/or use custom printed packing tape.
.plotters and large-format printers:Plotters are able to address the need that many businesses have to produce large print jobs on a regular basis. With Plotters you get what you pay for, and because the range of Plotters is wide you need to be sure of your business requirements and needs when comparing and selecting Plotters. For instance if you're an engineering or architectural firm that's going to be printing primarily large numbers based charts, then Plotters with precise color accuracy and consistency may not be what you're actually looking for based on price. However if you're a member of the graphics industry then certainly factors such as a wide color gamut, exceptionally high resolution, continuous tones, smooth transitions and other advanced printing technologies are going to be extremely important to you when evaluating Plotters.
At Super Warehouse we've got you covered from all angles with a diverse spectrum of Plotters from leading brands like HP. You'll have the ability to create accurate and consistent prepress proofs and technical documents as well high quality creative graphics. There are Plotters that have been designed for both small business and large enterprise. Choose by size with 13" Plotters, 17" Plotters, 24" Plotters, 36" Plotters, 42" Plotters, 44" Plotters and 60" Plotters available. You'll also find a variety of Plotter Paper, Inkjet Cartridges, Printer Memory, Network Print Servers and USB Cables available for Plotters.
