A general-purpose microprocessor chip designed to handle a wider array of instructions than a
RISC chip.
Compression Types - CORRECT ANSWER -
Core - CORRECT ANSWER - 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 - CORRECT ANSWER - (Central Processing Unit)
The main processing circuitry, or "chip," within a computer that contains the ALU, control unit,
and registers.
Data Bus - CORRECT ANSWER - An electronic pathway or circuit that connects
electronic components (such as the processor and RAM) on a computer's system board.
Device Driver - CORRECT ANSWER - A type of system software that provides the
computer with the means to control a peripheral device.
DNS Spoofing - CORRECT ANSWER - (Domain Name System)
A malicious attack on the domain name system in which the IP address corresponding to a Web
site is changed in order to redirect users to different locations.
