C) The CPU uses registers for temporary storage of internal commands and data.
What function does the external data bus have in the PC?
C) The external data bus provides a channel for the flow of data and commands between the CPU and RAM.
What is the function of the address bus in the PC?
D) The address bus enables the CPU to communicate with the memory controller chip.
Which of the following terms are measures of CPU speed?
A) Megahertz and gigahertz
The terms megahertz (MHz) and gigahertz (GHz) describe how many million or billion (respectively) cycles per second a CPU can run.
Which CPU feature enables the microprocessor to support running multiple operating systems at the same time?
D) Virtualization support
Intel and AMD CPUs come with virtualization support, enabling more efficient implementation of virtual machines.
Into which socket could you place an Intel Core i5 (Alder Lake)?
A) Socket LGA 1700
You’ll find Core i5 processors in several socket types, but the Alder Lake varieties fit LGA 1700.
Which feature enables a single-core CPU to function like two CPUs?
C) Hyperthreading
Intel loves its Hyperthreading, where a single-core CPU can function like a dual-core CPU as long as it has operating system support.
What steps do you need to take to install a Core i7 CPU into an AM4 motherboard?
D) Take all of the steps you want to take because it’s not going to work.
Intel and AMD processors are not compatible at all.
client calls to complain that his computer starts up, but crashes when Windows starts to load. After a brief set of questions, you find out that his nephew upgraded
his RAM for him over the weekend and couldn’t get the computer to work right afterward. What could be the problem?
D) Disconnected CPU fan
Most likely, the nephew disconnected the CPU fan to get at the RAM slots and simply forgot to plug it back in.
Darren has installed a new CPU in a client’s computer, but nothing happens when he pushes the power button on the case. The LED on the motherboard is
lit up, so he knows the system has power. What could the problem be?
D) He forgot to apply thermal paste between the CPU and the heat-sink and fan assembly.
The best answer here is that he forgot the thermal paste, though you can also make an argument for a disconnected fan.
A retail-boxed CPU usually comes with a ________ fan.
A) OEM
The fans that come with retail-boxed CPUs are known as Original Equipment Manufacturer (OEM) fans.
If virtually all desktop computers' power supplies come with a fan that blows air out of the system unit, why would someone add a fan to the front or side of the system unit?
C) To blow more cool air over other components
To blow more cool air over other components (like the video cards, hard drives, and motherboard).
On a CPU, which of the following cache levels is the smallest?
D) L1
The L1 cache is always the smallest and fastest of the CPU caches. The L2 and L3 caches are both larger and slower than the L1 cache. There is no such thing as an L4 cache in mainstream CPUs.
Albert is assembling a new PC from parts. When asked if he needed thermal compound, he glanced at his parts and said, "No." Why would Albert say such a thing?
A) His fan comes with thermal compound pre-applied on the bottom of the heat sink.
His heat sink and fan come with thermal compound pre-applied on the bottom of the heat sink. It's common for fans to come this way.
All CPU-fan combinations on a modern PC require thermal compound.
No heatsinks come with thermal compound pre-applied on the top of the heatsink.
Which type of memory inside a CPU is the slowest?
D) L3
L3 is the slowest memory inside a CPU. LCorrect Answer:
L2 is faster than L3 and L1 is faster than L2.
System RAM is slower than all of these, but it is not inside the CPU.
