ITE 272 Exam 2 Questions and Answers Latest Version 2025
fetch - Answers data inputs are prepared for transformation into data outputs
execution - Answers the transformation that takes place and the output is stored
control unit (CU) - Answers moves data, access instructions, and controls the arithmetic logic unit
registers - Answers internal storage locations in a CPU; each is capable of holding a single instruction or
data item instruction and instruction sets
op code - Answers the first group of bits and represents the instruction's unique binary number
operands - Answers In an instruction's bit string, they're groups of bits after the op code that hold the
instruction's input values; they can contain a data item or the location of a data item
move - Answers copies data to storage locations and can copy data between any combination of
registers and primary storage locations
load - Answers data transfer from main memory into a register
store - Answers data transfer from a register into primary storage
unconditional branch - Answers changes the sequence of the instruction's execution in the program
conditional branch - Answers changes the instruction execution only if the value is true
halt - Answers suspends the normal flow of the program
shift - Answers moves all values right or left; after shifting, empty positions are filled with 0s, and bit
values shifted beyond the bit string's bounds are discarded
complex instruction set computing (CISC) - Answers a philosophy of processor design that deliberately
includes complex instructions in the instruction set
reduced instruction set computing (RISC) - Answers a philosophy of processor design that limits the
number and type of complex instructions in the instruction set
clock rate - Answers the frequency at which the system clock generates timing pulses
cycle time - Answers the inverse of clock rate; the time required to fetch and execute the simplest
instruction in the instruction set
benchmarks - Answers measures of CPU or computer performance when carrying out one or more
specific tasks; used to compare performance
caching - Answers storing data in cache memory
