COMPUTER SCIENCE AN OVERVIEW CH. 2 QUESTIONS
WITH ACCURATE ANSWERS
Arithmetic/logic group correct answer Instructions that tell the control unit to
request an activity within the arithmetic/logic unit
Arithmetic/logic unit correct answer contains the circuitry that performs
operations on data
Bus correct answer CPU extracts data form main memory by supplying the
address of the pertinent memory cell along with an electronic signal telling the
memory circuitry that it is supposed to retrieve the data in the indicated cell.
CISC correct answer CPU's with the ability to execute a large number of complex
instructions, even though many of them are technically redundant.
Programs can exploit a powerful rick set of instruction, may requiring a multi-
instruction sequence in an RISC design.
Control correct answer Instructions that direct the execution of the program
rather than the manipulation of data
Control Unit correct answer contains the circuitry for coordinating the machines
activities
CPU correct answer The circuitry in a computer that controls the manipulation of
data
Brain/circuitry
