INSY 2303 EXAM 1 STUDY GUIDE QUESTIONS AND
CORRECT DETAILED ANSWERS (VERIFIED ANSWERS)
ALREADY GRADED A+
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.
