SOLUTIONS GRADED A+ TIP
✔✔Binary addition works with complex data types, such as floating-point and double-
precision numbers.
True or False - ✔✔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 - ✔✔T
✔✔Arithmetic SHIFT instructions are more complex when applied to twos complement
values because the rightmost bit is a sign bit.
True or False - ✔✔F
✔✔The BRANCH command has one operand containing the memory address of the
next instruction.
True or False - ✔✔T
✔✔An 8-bit op code provides 256 possible instructions numbered 0 through 255.
True or False - ✔✔T
✔✔A large set of complex instructions often goes hand in hand with fixed-length
instruction formats.
True or False - ✔✔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 - ✔✔F
✔✔A CPU is a complex system of interconnected electrical switches.
True or False - ✔✔T
✔✔A perfect conductor can be described as one having maximum resistance.
True or False - ✔✔F
,✔✔Electricity travels through a trace at approximately 50% of the speed of light.
True or False - ✔✔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 - ✔✔T
✔✔Transistors and the tracks that interconnect them are the fundamental building
blocks of all CPUs.
True or False - ✔✔F
✔✔Circuits reduced manufacturing cost per circuit because many chips could be
manufactured in a single sheet, or wafer.
True or False - ✔✔T
✔✔The PC revolution wouldn't have been possible without standardized
microprocessors.
True or False - ✔✔T
✔✔According to Moore's Law, the doubling of transistor density is achieved with a 50%
increase in unit cost.
True or False - ✔✔F
✔✔Current fabrication technology is capable of squeezing more than two billion
transistors onto a wafer of silicon approximately one square centimeter.
True or False - ✔✔F
✔✔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.
True or False - ✔✔T
✔✔Low voltage circuits are less susceptible to damage from voltage surges and static
electricity.
True or False - ✔✔F
, ✔✔Early Xeon processors filled an important niche in the small server market but
weren't powerful enough to perform processing duties in many large-scale servers.
True or False - ✔✔T
✔✔Practical optical processors will probably appear first as full-fledged computer
processors
True or False - ✔✔F
✔✔Traditional bus interfaces are too slow and power hungry to provide sufficient data
transfer capacity between many processors or between processors and primary
storage.
True or False - ✔✔T
✔✔As currently envisioned, quantum computing offers no benefit compared with
conventional electrical processors for problem types that don't require massively parallel
computation.
True or False - ✔✔T
✔✔The ____ section of the CPU performs all computation and comparison operations.
a. register
b. ALU

perform.
a. cycle
b. process
c. operand
