Short Answer

1. A network attached storage (NAS) device is a server connected to a network with the sole purpose of providing storage.

Home and small business users can add up to 6 TB or more of hard disk storage space to their network with a NAS device.

2.  The advantages of SAS (serial-attached SCSI) include thinner, longer cables; reduced interference; less expensive; support for many more connected devices at once; and faster speeds.

SAS interfaces support connections to optical disc drives, printers, scanners, digital cameras, and other devices.

3. A single-session disc means manufacturers write all items on the disc at one time. rather than Multisession means you can write on part of the disc at one time and another part at a later time.

The purpose of archive discs and Picture CDs is to preserve their photos.

4. Users use memory cards because memory cards enable mobile users easily to transport digital photos, music, or files to and from mobile devices and computers or other devices.

Five types of memory cards are first, CompactFlash (CF), CF has a storage capacity of 512 MB to 100 GB. It’s use for Digital cameras, smart phones, PDAs, photo printers, portable media players, notebook computers, desktop computers. second, Secure Digital (SD), SD has a storage capacity of 512 MB to 8 GB. It’s use for Digital cameras, digital video cameras, smart phones, PDAs, photo printers, portable media players. Third, SDHC has a storage capacity of 4 to 32 GB. It’s use for Digital cameras. Fourth, microSD has a storage capacity of 1 to 2 GB. It’s use for Smart phones, portable media players, handheld game consoles, handheld navigation devices. Last is microSDHC, it has a storage capacity of 4 to 16 GB. It’s use for Smart phones, portable media players, handheld game consoles, handheld navigation devices.

5. The one difference between microfilm and microfiche is that Microfilm is a 100- to 215-foot roll of film. Microfiche is a small sheet of film, usually about 4 X 6 inches.

Microfilm and microfiche use is widespread, with many companies allowing you to search through and view microfilm images online. Libraries use these media to store back issues of newspapers, magazines, and genealogy records. Some large organizations use microfilm and microfiche to archive inactive files. Some banks use them to store transactions and canceled checks. The U.S. Army uses them to store personnel records.

Short Answer

1. Resolution affect images displayed on a monitor by having a higher resolution, it uses a greater number of pixels and thus provides a smoother, sharper, and clearer image. As you increase the resolution, however, some items on the screen appear smaller.

Resolution relate to the size of an LCD monitor or screen because resolution is the number of horizontal and vertical pixels in a display device. For example, a monitor that has a 1440 X 900 resolution displays up to 1440 pixels per horizontal row and 900 pixels per vertical row, for a total of 1,296,000 pixels to create a screen image.

2. Some of the features of HDTV are it works with digital broadcast signals, transmitting digital sound, supporting wide screens, and providing resolutions up to 1920 X 1080 pixels.

Game console users set up the output for the consoles by pluging one end of a cable in the game console and the other end in the video port on the television.

3. The two types of wireless printing technology are Bluetooth printing and infrared printing .

With Bluetooth printing, a computer or other device transmits output to a printer via radio waves. The computer or other device and the printer do not have to be aligned with each other; rather, they need to be within an approx i mate 30-foot range. With infrared printing, a printer communicates with a computer or other device using infrared light waves. To print from a smart phone, for example, a user lines up the IrDA port on the smart phone with the IrDA port on the printer.

4. An ink-jet printer works by forming characters and graphics by spraying tiny drops of liquid ink onto a piece of paper.

Professional applications requiring high image quality, such as photography studios, medical labs, and security identification systems, use dye-sublimation printers. These high-end printers cost thousands of dollars and print images in a wide range of sizes. Most dye-sublimation printers for the home or small business user, by contrast, typically print images in only one or two sizes and are much slower than their professional counterparts. These lower-end dye-sublimation printers are comparable in cost to a photoprinter based on ink-jet technology. Some are small enough for the mobile user to carry the printer in a briefcase.

5. Most surround sound computer speaker systems include one or two center speakers and two or more satellite speakers that are positioned so that sound emits from all directions.

Audio resolution is the number of bytes that represent sound in a given time, is stated as a bit rate such as 8-bit, 16-bit, or 24-bit. An 8-bit resolution, the sound quality is similar to an AM radio; 16-bit resolution yields optical disc-quality sound; and 24-bit resolution is used for high-quality digital audio editing.

Short Answer Write a brief answer to each of the following questions.

1. With the slate Tablet PC, which

typically does not include a keyboard, the system

unit is behind the display. On a convertible

Tablet PC, by contrast, the system unit is

positioned below a keyboard, providing functionality

similar to a traditional notebook computer

or netbook. The difference is the display

attaches to the system unit with a swivel-type

hinge, which enables a user to rotate the display

and fold it down over the keyboard to look

like a slate Tablet PC

.2. The motherboard, sometimes called a system

board, is the main circuit board of the system

unit. Computer chip is a small piece of semiconducting

material, usually silicon, on which

integrated circuits are etched.

3. fetching, decoding, executing, and,

storing. Function of registers are storing the

location from where an instruction was fetched,

storing an instruction while the control unit

decodes it, storing data while the ALU computes

it, and storing the results of a calculation.

4. Many computers,

peripherals, smart phones, PDAs, cars, and

other consumer electronics are Bluetooth-enabledIf you have a computer that is not Bluetooth

enabled, you can purchase a Bluetooth wireless port

adapterthat will convert an existing USB port

into a Bluetooth port. Also available

are Bluetooth PC Cards and ExpressCard

modules for traditional notebook computers and

Tablet PCs, and Bluetooth cards for smart phones

and PDAs.

5. Use compressed air to blow away dust from any

openings on the computer or device case, such

as drives, slots, ports, and fan vents.

Preparing :

lint from difficult-to-reach areas; removes

sticky liquid spilled on keyboards

• lint-free antistatic wipes and swabs

• screen cleaning solution or 50/50 mix of

rubbing alcohol and water (do not use

ammonia-based solutions)

• small computer vacuum (or small attachments

on your house vacuum)

• antistatic wristband — to avoid damaging

internal components with static electricity

• small screwdriver (may be required to

open the case or remove adapter cards)

Before cleaning the exterior of a computer

or mobile device, turn it off, and if necessary,

unplug it from the electrical outlet, remove its

battery, and disconnect all cables from the ports.
