Terms in this set (51)
a peripheral device, as a keyboard or stylus, used to enter data into a computer for processing.
A Keyboard that is customized to complete/launch certain tasks.
Graphic user Interface
A computer program designed to allow a computer user to interact easily with the computer typically by making choices from menus or groups of icons.
A type of computer mouse that uses light-emitting and -sensing devices to detect where it is
An input device which captures the handwriting or brush strokes of a user, converts handwritten analog information created using pen and paper into digital data, enabling the data to be utilized in various applications.
A representation in which each item corresponds to one or more bits of information, especially the information used to control the display of a computer screen.
Dots Per Inch (DPI)
A measure of spatial printing or video dot density, in particular the number of individual dots that can be placed in a line within the span of 1 inch
Optical Character Recognition (OCR)
The identification of printed characters using photoelectric devices and computer software.
Universal Product Code (UPC)
More formal term for "Barcode"
The motion pictures that are entered into the computer.
Voice Recognition Program/Software
computer software program or hardware device with the ability to decode the human voice.
Speech Recognition Program
Voice or speech recognition is the ability of a machine or program to receive and interpret dictation, or to understand and carry out spoken commands.
The set of symbolic instruction codes usually in binary form that is used to represent operations and data in a machine.
A small piece, part, or quantity of something
A number expressed in the binary numeral system or base-2 numeral system which represents numeric values using two different symbols: typically 0 and 1.
A group of binary digits or bits (usually eight)operated on as a unit.
American Standard Code for information Interchange (ASCII)
A standardized code in which characters are represented for computer storage and transmission by the numbers 0 through 127.
Difference between the computer and peripheral devices, such as the monitor, keyboard, and mouse.
A printed circuit board containing the principal components of a computer or other device, with connectors into which other circuit boards can be slotted.
Find or discover by investigation.
A computer processor on a microchip.
Crystalline or amorphous solids with distinct electrical characteristics.
A component of a computer's central processing unit (CPU) that directs the operation of the processor.
A microprocessor designed to supplement the capabilities of the primary processor.
An integrated circuit dedicated to the rapid rendering of graphics.
Dynamic random-access memory (DRAM) is a type of storage that is widely used as the main memory for a computer system.
Random access memory (RAM) that retains data bits in its memory as long as power is being supplied. Unlike dynamic RAM (DRAM), which stores bits in cells consisting of a capacitor and a transistor, SRAM does not have to be periodically refreshed.
A unit of memory or data equal to 1,024 (210) bytes.
A unit of information equal to 220 bytes or, loosely, one million bytes.
A collection of items of the same type stored in a hidden or inaccessible place.
Read Only Memory (ROM)
Memory read at high speed but not capable of being changed by program instructions.
Memory Access Time
How long it takes for a character in memory to be transferred to or from the CPU.
Basic Input/ Output Systems (BIOS)
The program a personal computer's microprocessor uses to get the computer system started after you turn it on.
Power-On Self-Test (POST)
The diagnostic testing sequence that a computer's basic input/output system (or "starting program") runs to determine if the computer keyboard, random access memory, disk drives, and other hardware are working correctly.
A kind of memory that retains data in the absence of a power supply.
A place in a computer where an expansion card can be inserted.
A device that can be slotted into a computer to allow the use of audio components for multimedia applications.
A printed circuit board that controls the output to a display screen.
Network Interface Card
Contains the electronic circuitry required to communicate using a wired connection or a wireless connection.
Internal type of modem that is plugged into the PCI slot of a PC motherboard.
Universal Serial Bus (USB) Port
A common interface that enables communication between devices and a host controller such as a personal computer (PC).
A connector by which a device that sends data one bit at a time may be connected to a computer.
A connector for a device that sends or receives several bits of data simultaneously by using more than one wire.
A socket on the back of a computer used to connect a monitor.
A process-specific or an application-specific software construct serving as a communication endpoint, which is used by the Transport Layer protocols of Internet Protocol suite.
A device or program that enables a computer to transmit data over, for example, telephone or cable lines.
A device in which a laptop computer, smartphone, or other mobile device may be placed for charging, providing access to a power supply and to peripheral devices or auxiliary features.
A single computer bus that connects the major components of a computer system, combining the functions of a data bus to carry information.
Peripheral Component Interconnect (PCI) Bus
An interconnection system between a microprocessor and attached devices in which expansion slots are spaced closely for high speed operation.
Component Interconnect (PCI) Bus
Attached devices can take either the form of an integrated circuit fitted onto the motherboard itself (called a planar device in the PCI specification) or an expansion card that fits into a slot.
Accelerated Graphics Port
A high-speed point-to-point channel for attaching a video card to a computer system, primarily to assist in the acceleration of 3D computer graphics.
