Bit The smallest unit of information handled by a computer. A bit is one of two values, either
a 0 or a 1. Eight bits constitute a byte, which can represent a letter or a number.
byte An 8-bit unit of data that represents a single character.
digital data Text, numbers, graphics, or sound represented by discrete digits, such as 1s and
0s.
analog data Data that is measured or represented on a continuously varying scale, such as a
dimmer switch or a watch with a sweep second hand.
Digitization Converting non-digital information or media to a digital format through the use
of a scanner, sampler, or other input device.
Lossy compression Any data compression technique in which some of the data is sacrificed
to obtain more compression.
Lossless compression A compression technique that is able to reconstitute all of the data in
the original file; hence, lossless means that this compression technique does not lose data.
image resolution The number of pixels in an image, usually expressed as horizontal pixels ×
vertical pixels.
Aspect ratio The ratio of the width and height of an image or display screen.
pixel interpolation A process that is used by graphics software to average the color of
adjacent pixels in an image, usually when the image is enlarged.
, Sampling rate The number of times per second a sound is measured during the recording
process.
Data In the context of computing and data management, the symbols that a computer uses
to represent facts and ideas.
information system A computer system that collects, stores, and processes information,
usually within the context of an organization.
bitmap graphic An image, such as a digital photo, that is stored as a gridwork of colored
dots.
vector graphic -An image generated from descriptions that specify the position, length, and
direction in which lines and shapes are drawn.
3D graphics A digital graphics format that displays a three-dimensional image in a two-
dimensional space.
instruction set The collection of instructions that a CPU is designed to process.
software The instructionns that direct a computer to perform a task, interact with a user, or
process data.
mainframe A large, fast, and expensive computer generally used by businesses or
government agencies to provide centralized storage, processing, and management for large
amounts of data.
Supercomputer The fastest and most expensive type of computer, capable of processing
trillions of instructions per second.
