INSY 2303 Exam 1
AAC - Answer (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
Exentions: .aac, .mp4, .m4p
disadvantages: files can be protected so that use is limited to approved devices.
ALU - Answer (Arithmetic Logic Unit) part of the CPU that performs arithmetic and
logical operations on the numbers stored in its registers
ARPANET - Answer (Advanced Research Projects Agency Network) one of the first
packet switching computer networks that uses TCP/IP and was the prototype for the
internet.
Created in 1969
ASCII - Answer (American Standard Code for Information Interchange) code that
represents characters as a series of 1s and 0s and is used by most computers to
represent text. it provides codes for 128 characters
Bandwidth - Answer data transmission capacity of a communication channel measured
in bits per second, analog signals are measured in hertz.
a high-bandwidth channel carries more data than a low-bandwidth channel
Binary Number System (Binary) - Answer Method for representing numbers using only 2
digits, 0s and 1s, in contrast to the decimal number system which uses 10 digits.
BMP - Answer (aka "bump") native bitmap file format of Microsoft windows used for
buttons and other controls for graphical user interface
Theses files are often too large for email attachments and aren't supported by most
browsers
Mobile Broadband Service (broadband) - Answer High-bandwidth wireless technology
that was developed for sending digital data over cell phone systems. Data is transmitted
by a signal flow between the device and the cellular radio tower
CISC - Answer (Complex Instruction Set Computer) A general-purpose microprocessor
chip designed to handle a wider array of instructions than a RISC chip.
This technology is used in most of today's laptops and desktops.
Data Compression Types - Answer Data Compression- any technique that re-codes
data in a file so that it contains fewer bits.
, Lossless Compression-every bit of data that is originally in the file remains when it is
uncompressed.
Lossy Compression- reduces a file permanently; the original is not that same as when it
is uncompressed.
Core - Answer consists of the control unit and the ALU; Part of the CPU that receives
instructions and performs calculation s, or actions , based on those instructions.
Control unit- part of the microprocessor that directs and coordinates processing.
CPU - Answer (central processing unit) main processing circuitry (chip) that contains the
ALU, control unit, and registers.
Data Bus - Answer electronic pathway or circuit that connects electronic components on
a computers system board.
Local bus- connects CPU and RAM
Expansion bus- connects ram to expansion ports.
Device Driver - Answer software that provides the computer with the means to control a
peripheral device by establishing communication with it. Operating systems include
some standard built in drivers for expansion ports.
DNS spoofing - Answer Malicious attack on the domain name system in which the IP
address corresponding to a website is changed to redirect users to different locations
DNS- (domain Name Servers) large database of unique IP addresses corresponding to
domain names
Dynamic Addresses - Answer temporarily assigned IP addresses usually provided by an
ISP (internet service provider), unlike a static IP address which is permanently assigned
and is used by hosts or servers.
Form Factor - Answer Configuration of a computers system unit. Examples include: mini
tower, tower, cube.
GIF - Answer (graphics Interchange Format) designed to create images to be displayed
on multiple platforms (PC and Mac) and is limited to 256 colors, supports simple
animations, and is a bitmap. It is being replaces by JPEG and PNG on webpages.
Handshake - Answer A protocol for the beginning of an interaction; the first talking of
two computers; negotiation of protocols
