ITE 221 EXAM 2 QUESTIONS AND ANSWERS
The ALU component of the CPU moves data and instructions between main memory and registers.
True or false - CORRECT ANSWER✅✅F
A complex chain of events occurs when the CPU executes a program.
True or False - CORRECT ANSWER✅✅T
The CPU alternates constantly between fetch and execution cycles.
True or False - CORRECT ANSWER✅✅T
The operand of a CPU instruction cannot contain the location of a data item.
True or False - CORRECT ANSWER✅✅F
Data inputs are accessed from storage or extracted directly from the operands and stored in one or
more registers.
True or False - CORRECT ANSWER✅✅T
The control unit cannot execute instructions without assistance from the ALU.
True or False - CORRECT ANSWER✅✅F
MOVE tests the bit values in the source location and moves these values to the destination location.
,True or False - CORRECT ANSWER✅✅F
With bit strings, NOT treats each bit in the bit string as a separate Boolean value.
True or False - CORRECT ANSWER✅✅T
Binary addition works with complex data types, such as floating-point and double-precision numbers.
True or False - CORRECT ANSWER✅✅F
Shifting an 8-bit twos complement value to the right by seven positions is a simple way to extract and
test the sign bit.
True or False - CORRECT ANSWER✅✅T
Arithmetic SHIFT instructions are more complex when applied to twos complement values because the
rightmost bit is a sign bit.
True or False - CORRECT ANSWER✅✅F
The BRANCH command has one operand containing the memory address of the next instruction.
True or False - CORRECT ANSWER✅✅T
An 8-bit op code provides 256 possible instructions numbered 0 through 255.
True or False - CORRECT ANSWER✅✅T
A large set of complex instructions often goes hand in hand with fixed-length instruction formats.
, True or False - CORRECT ANSWER✅✅F
Compared with CISC processors, RISC processors are efficient at executing programs that do many of the
functions complex instructions are designed for.
True or False - CORRECT ANSWER✅✅F
A CPU is a complex system of interconnected electrical switches.
True or False - CORRECT ANSWER✅✅T
A perfect conductor can be described as one having maximum resistance.
True or False - CORRECT ANSWER✅✅F
Electricity travels through a trace at approximately 50% of the speed of light.
True or False - CORRECT ANSWER✅✅F
The earliest computers were constructed with ordinary copper wire and vacuum tube switches and
were unreliable because of the heat the vacuum tubes generated.
True or False - CORRECT ANSWER✅✅T
Transistors and the tracks that interconnect them are the fundamental building blocks of all CPUs.
