Essay Quiz Answers
1. This chapter talks about motherboards made in layers that contain the wires or traces. Find an
Internet site that talks about the motherboard manufacturing process. Why do you think
motherboards are made in layers? What advantages do the layers provide?
Answer: Answers will vary. The main point of the layered structure of the motherboard is
that it may contain multiple layers of wires or traces without their signals interfering with
each other. The layered approach allows the manufacturer to add complexity and additional
components to the board without extending the overall length and width of the board. Shorter
traces also allow signals to travel faster than they would if the wires were longer, as would be
necessary if motherboards did not use layers. The multiple layers also add strength to the
board itself, so it doesn’t bend easily.
2. Some people believe that selecting a motherboard based on the motherboard chipset is even
more important than basing the decision on the kind of processor. Do you agree or disagree,
and why?

Answer: Answers will vary. If the student agrees, the student will likely point out that the
chipset determines what kind of processor and RAM the computer supports. It also
determines performance and upgradeability. The flip side of the argument revolves around
choice of CPU. If you know you want the latest hot-rod processor from AMD, for example,
you can then find the right chipset and motherboard to support it. Choosing that CPU will
also almost always dictate the type of RAM you can use.
3. Prepare a PowerPoint presentation or write a paper that would help your classmates select
and replace a bad motherboard. Be sure to walk through all of the necessary steps.
Answer: The answers may include several points, such as the following:

Determine what motherboard you need and make sure your CPU will work with the
motherboard.

Make sure the motherboard form factor matches the case and will fit inside the box.

Be sure you can return the motherboard if it does not match your CPU or case.

After unplugging the computer, remove any cards or drives that prevent you from
accessing the motherboard.

Remove the power connector from the old motherboard.

Unscrew the old motherboard and lift it out.

Check to see if you need to move any of the standouts before the new motherboard will
fit into the case. Use as many standouts as your new motherboard will support.

If you are going to use the same CPU or RAM, remove it from the old motherboard and
place it into the new one. If you have a new CPU or new RAM, insert it into the new
motherboard. Also place the CPU fan into position before you attempt to insert the
motherboard into the case.

Plug in the wires for the LEDs and buttons on the front of the box, making sure you align
the positive and negative connections as directed in the motherboard book.

4. Your neighbors Dora and Jim just learned that you’re studying computer hardware. They feel
that their computer is slightly out of date. They want to upgrade the processor, but not the
motherboard. Prepare a list of at least five questions you should ask them before you know
what CPU they can choose or whether it is feasible to upgrade their system.
Answer: Answers will vary. Questions might include the following:

Who is the manufacturer and what is the model of your current CPU?

What kind of CPU socket or slot does your motherboard have?

Who is the manufacturer and what is the model of your motherboard?

What chipset does your motherboard use?

How much RAM does your computer currently have?

Why do you want to upgrade your CPU?

Are you sure you want to upgrade only the CPU or are you willing to upgrade the
motherboard and the RAM as well?

 DDR2 speeds, clock/I/O speed format (MHz): 100/200, 133/266, 166/333, 200/400,
250/500

DDR3 speeds, clock/I/O speed format (MHz): 100/400, 133/533, 166/667, 200/800
2. The CPUs that support DDR3 memory as of this writing are AMD Phenom II and Intel Core
i7.
BIOS
Many devices have a BIOS chip on the device itself. Things like RAID and sound cards have a
ROM chip onboard that contains BIOS for that device. More common and necessary devices,
like a keyboard or optical drive, have their BIOS stored in a ROM chip on the motherboard.
