WITH COMPLETE SOLUTION!!
The ALU component of the CPU moves data and instructions between main
memory and registers.
True or false Answer - F
A complex chain of events occurs when the CPU executes a program.
True or False Answer - T
The CPU alternates constantly between fetch and execution cycles.
True or False Answer - T
The operand of a CPU instruction cannot contain the location of a data item.
True or False Answer - F
Data inputs are accessed from storage or extracted directly from the operands
and stored in one or more registers.
True or False Answer - T
,The control unit cannot execute instructions without assistance from the ALU.
True or False Answer - F
MOVE tests the bit values in the source location and moves these values to the
destination location.
True or False Answer - F
With bit strings, NOT treats each bit in the bit string as a separate Boolean
value.
True or False Answer - T
Binary addition works with complex data types, such as floating-point and
double-precision numbers.
True or False 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 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 Answer - F
,The BRANCH command has one operand containing the memory address of
the next instruction.
True or False Answer - T
An 8-bit op code provides 256 possible instructions numbered 0 through 255.
True or False Answer - T
A large set of complex instructions often goes hand in hand with fixed-length
instruction formats.
True or False 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 Answer - F
A CPU is a complex system of interconnected electrical switches.
True or False Answer - T
A perfect conductor can be described as one having maximum resistance.
True or False Answer - F
, Electricity travels through a trace at approximately 50% of the speed of light.
True or False 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 Answer - T
Transistors and the tracks that interconnect them are the fundamental building
blocks of all CPUs.
True or False Answer - F
Circuits reduced manufacturing cost per circuit because many chips could be
manufactured in a single sheet, or wafer.
True or False Answer - T
The PC revolution wouldn't have been possible without standardized
microprocessors.
True or False Answer - T
According to Moore's Law, the doubling of transistor density is achieved with a
50% increase in unit cost.
