Compact disc-read-only memory, a type of optical disk that contains data that cannot be changed; CD-ROM's are commonly used to distribute commercial software programs.
A common optical drive in computers that can read data from CD-ROM disks.
Compact disk-rewritable, an optical disk that allows writing, erasing, and rewriting.
A disk drive that read and write on rewritable optical disks.
Camera that captures images and stores them as bit patterns on disks or other digital storage media instead of using film.
Converting information into a digital form that can be stored in the computer's memory.
Smmal, magnetically sensitive, flexible plastic wafers housed in a plastic case, used as a storage device.
Device that allows 3 1/2 or 4 1/2 disks to be inserted into the computer.
Output device that displays text and graohics onscreen.
Type of compact printer, which forms images by physically striking paper, ribbon, and print hammer together, the way a typewriter does.
Type of optical disk with multigigabyte capacity that can be read, written, and erased.
Optical disk drive that can read high-capacity DVD disks.
Keyboard that places the keys at angles that allow your wrists to assume a more natural position while you type, potentially reducing the risk of repetitive-stress injuries.
Sciene of designing work environments that enable people and things to interact efficiently and safely.
Output device capable of sending, in effect, a photocopy through a telephone line, allowing for fast and convenient transmission of information stored on paper.
Hardware peripheral that enables a computer to send onscreen documents to a receiving fax machine by translating the document into signals that can be sent over phone wires and decoded by the receiving fax machine.
Uses IEEE standard 1394.
Type of erasable memory chip used in cell phones, pagers, portable computers, and handheld computers, among other things.
Pressure-sensitive touch tablet used as a pointing device. The user presses on the tablet with a stylus.
handwriting recognition software
Software that translates the user's handwritten forms into ASCII characters.
printer radio frequency identification reader
Output device that produces a paper copy of any information that can be displayed on the screen.
reader radio frequency identification tag
Reading tool taht uses radio waves to communicate with RFID tags.
Storage method that allows information retrieval without regard to the order in which it was recorded.
Conditions that result from repeating the same movements over long periods, such as keyboarding-induced carpal tunnel syndrome, a painful affliction of the wrist and hand.
Density of pixels, measured by the number of dots per inch.
An input device that makes a digital representation of any printed image. See flatbed scanners, slide scanners, drum scanners, and sheetfed scanners.
Storage method that requires the user to retrieve information by zipping through it in the order in which it was recorded.
Storage, such as flash memory, with no moving parts. Solid-state storage is likely to replace disk storage in the future.
A circuit board that allows the PC to accept microphone input, play music and other sound through speakers or headphones, and process sound in a variety of ways.
Long-term repository for data. Disks and tape drives are examples.
Storage device that uses magnetic tape to store information.
Pointing device that responds when the user points to or touches different screen regions.
A small flat-panel pointing device that is sensitive to light pressure. The user moves the pointer by dragging a finger across the pad.
Pointing device that remains stationary while the user moves a protruding ball to control the pointer on the screen.
universal serial bus
A data path standard that theoretically allows up to 126 devices, such as keyboards, digital cameras, and scanners, to be chained together from a single port, allowing for data transmission that is much faster and more flexible than through traditional serial and parallel ports.
