Questions with 100% Verified Answers
Question: The ALU component of the CPU moves data and instructions between main memory and registers.
Answer:
F
Question: A complex chain of events occurs when the CPU executes a program.
Answer:
T
Question: The CPU alternates constantly between fetch and execution cycles.
Answer:
T
Question: The operand of a CPU instruction cannot contain the location of a data item.
Answer:
F
Question: Data inputs are accessed from storage or extracted directly from the operands and stored in one or
more registers.
Answer:
T
Question: The control unit cannot execute instructions without assistance from the ALU.
Answer:
F
Question: MOVE tests the bit values in the source location and moves these values to the destination location.
Answer:
F
Question: With bit strings, NOT treats each bit in the bit string as a separate Boolean value.
Answer:
T
,Question: Binary addition works with complex data types, such as floating-point and double-precision
numbers.
Answer:
F
Question: Shifting an 8-bit twos complement value to the right by seven positions is a simple way to extract
and test the sign bit.
Answer:
T
Question: Arithmetic SHIFT instructions are more complex when applied to twos complement values because
the rightmost bit is a sign bit.
Answer:
F
Question: The BRANCH command has one operand containing the memory address of the next instruction.
Answer:
T
Question: An 8-bit op code provides 256 possible instructions numbered 0 through 255.
Answer:
T
Question: A large set of complex instructions often goes hand in hand with fixed-length instruction formats.
Answer:
F
Question: Compared with CISC processors, RISC processors are efficient at executing programs that do many
of the functions complex instructions are designed for.
Answer:
F
Question: A CPU is a complex system of interconnected electrical switches.
Answer:
T
Question: A perfect conductor can be described as one having maximum resistance.
, Answer:
F
Question: Electricity travels through a trace at approximately 50% of the speed of light.
Answer:
F
Question: The earliest computers were constructed with ordinary copper wire and vacuum tube switches and
were unreliable because of the heat the vacuum tubes generated.
Answer:
T
Question: Transistors and the tracks that interconnect them are the fundamental building blocks of all CPUs.
Answer:
F
Question: Circuits reduced manufacturing cost per circuit because many chips could be manufactured in a
single sheet, or wafer.
Answer:
T
Question: The PC revolution wouldn't have been possible without standardized microprocessors.
Answer:
T
Question: According to Moore's Law, the doubling of transistor density is achieved with a 50% increase in unit
cost.
Answer:
F
Question: Current fabrication technology is capable of squeezing more than two billion transistors onto a wafer
of silicon approximately one square centimeter.
Answer:
F
Question: A microprocessor that fails to perform reliably at a higher clock rate might still be usable and rated
for sale at a lower clock rate.
