manner that is unexpected and unwanted by the user.
analog signal - CORRECT-ANSWERSa wavy signal. A modem converts the computers digital
signal into an analog signals that can be transmitted over dial up internet connections and can
transverse ordinary phone lines.
,anti-spyware software - CORRECT-ANSWERSScans for know spyware programs and removes
them from the system.
anti-virus software - CORRECT-ANSWERSSoftware that identifies the presence of a virus and
is capable of removing or quarantining the virus.
application software - CORRECT-ANSWERSThe set of programs on a computer that helps a
user carry out tasks such as word processing, sending e-mail, balancing a budget, creating
presentations, editing photos, taking an online course, and playing games.
architecture - CORRECT-ANSWERS(computer science) the structure and organization of a
computer's hardware or system software
ASCII - CORRECT-ANSWERSAmerican standard Code for Information Interchange, The
American Standard Code for Information Interchange. It is a mapping that takes common
characters in American English and maps them to number so that they can be represented on
a computer. For example, "A" maps to the decimal number 65 or the byte 01000001.
BD-R - CORRECT-ANSWERS(Blu-ray disc recordable) A Blu-ray disc that can be recorded on
one time.
,BD-RE - CORRECT-ANSWERSBD-RE (Blu-ray Disc Rewritable) can be erased and re-
recorded multiple times.
BIOS - CORRECT-ANSWERSA coded program that is executed when the computer system is
first turned on the provides low-level access to the hard disk, video, and keyboard.
binary digit - CORRECT-ANSWERSThe means by which computers represent data; also called
bits. It is either a zero or a one. (ECC7) or 1=on, 0-off
bits per second - CORRECT-ANSWERSA unit or measurement describing the number of bits of
data transmitted electronically in one second. Bps
Bluetooth - CORRECT-ANSWERSA wireless standard for using radio waves to communicate
between devices. Class 3 Bluetooth devices (the most common) communicate at distances up
to one meter.
Blu-ray - CORRECT-ANSWERSBlu-ray is an optical disc format such as CD and DVD. It was
developed for recording and playing back high-definition (HD) video and for storing large
amounts of data. While a CD can hold 700 MB of data and a basic DVD can hold 4.7 GB of
data, a single Blu-ray disc can hold up to 25 GB of data.
, boot process - CORRECT-ANSWERSSequence of events that occurs between the time you turn
on a computer and the time that it becomes ready to accept commands. Simply the act of
turning your computer on.
broadband connection - CORRECT-ANSWERSAn Internet connection such as DSL or cable
modem that offers higher bandwidth, and therefore faster transmission speed, than standard
modem connections.
byte - CORRECT-ANSWERSa sequence of 8 bits (enough to represent one character of
alphanumeric data) processed as a single unit of information
cable - CORRECT-ANSWERSA bundle of wires covered by rubber or plastic along which an
electric current can pass, such as attach a peripheral device to a computer port.
cache memory - CORRECT-ANSWERSSmall blocks of memory, located directly on and next to
the central processing unit (CPU) chip, that act as holding places for recently or frequently
used instructions or data that the CPU accesses the most. When these instructions or data are
stored in cache memory, the CPU can more quickly retrieve them than if it had to access the
instructions or data from random access memory (RAM).
