AAC - ANS Advanced Audio Coding
A file format that provides highly compressed audio files with very little loss of sound quality
and is promoted by Apple on its iTunes Web site.
ALU - ANS (Arithmetic Logic Unit) The part of the CPU that performs arithmetic and logical
operations on the numbers stored in its registers.
ARPANET - ANS (Advanced Research Projects Agency Network) One of the first packet
switching computer networks using TCP/IP, and the prototype for the Internet.
ASCII - ANS (American Standard Code for Information Interchange) A code that represents
characters as a series of 1s and 0s. Most computers use ASCII code to represent text, making it
possible to transfer data between computers
Bandwidth - ANS The data transmission capacity of a communications channel. Digital signals
are measured in bits per second; analog signals in hertz.
Binary - ANS The representation of data using two states, such as off-on or 1-0.

, BMP - ANS Bitmap
The native bitmap graphics file format of Microsoft Windows.
BN - ANS Backbone Network
high-speed network that connects many networks.
Broadband - ANS A term used to refer to communications channels that have bandwidth that
equals or exceeds 25 Mbps
CISC - ANS (complex instruction set computer) A general-purpose microprocessor chip
designed to handle a wider array of instructions than a RISC chip.
Compression Types - ANS losless: refers to compression in which the image is reduced
without any quality loss
lossy: able to reduce a file down to a much smaller file size than lossless, due to the nature of
how it works.
Core - ANS A core is part of a CPU that receives instructions and performs calculations, or
actions, based on those instructions. A set of instructions can allow a software program perform
a specific function. Processors can have a single core or multiple cores.
CPU - ANS Central Processing Unit
The main processing circuitry, or "chip," within a computer that contains the ALU, control unit,
and registers.
