Multiple Choice

What is parallelization?

• Process of two or more lines never intersecting on your screen.

• The lines in a bus that carry data to your CPU, preventing crossover.

• Splitting the tasks a CPU does up between cores.

• Running 2 or more CPUS on the same motherboard.

Multiple Choice

Why are multiple cores not needed for gaming as much as other programs?

• Things like AI and reactions to inputs require things be done in a certain order, and cannot be parallelized as easy.

• The math needed for games isn't advanced enough for parallelization.

• Gamers can't afford multiple cores because of their expensive Graphics Cards.

• They are needed; in fact gamers need as many cores as possible.

Multiple Choice

Who invented Hyper-threading?

• Windows

• Apple

• Intel

• AMD

Multiple Choice

Hyper-Threading doubles the number of physical cores.

• false

• true

Multiple Choice

Hyper-Threading virtually doubles the number of logical cores,

• true

• false

Multiple Choice

What is the main function of Hyper-Threading?

• Overclock the CPU without using the BIOS.

• Allow the threads to bypass the bus, making it faster to the Hard Drive.

• Increase amount of independent instructions in the pipeline.

• Makes graphics better and perform at a higher FPS than a CPU without Hyper-Threading.

Multiple Choice

What is the difference between DRAM and SRAM?

• DRAM needs to be refreshed, SRAM doesn't,

• DRAM is a newer, faster version of SRAM.

• DRAM and SRAM are the same, just used in different locations on the CPU.

• DRAM is faster and more efficient than SRAM

Multiple Choice

What happens when the CPU cache is full?

• The computer shuts down.

• The computer uses RAM instead, and slows down.

• Nothing really.

• The cache is cleared and the processes start over.

Open Ended

What is a bottleneck in terms of computing?

Multiple Choice

Why is level 3 cache sometimes called shared cache?

• It works with the motherboard better than other levels.

• Its memory is shared with the multiple cores in the CPU.

• It can store more types of information than the other levels.

• It is just a fancy way to say Level 1 and Level 2 at the same time, because they share a space on the CPU.

Multiple Choice

What would happen if a CPU wasn't cooled?

• The computer would slow down a lot.

• The computer would make the room really warm.

• The CPU would fry itself in about 10 seconds.

• The CPU would make a loud beeping noise until it is cooled off.

Multiple Choice

What is a heat sink?

• A pool where all of the heat goes in. It has to be drained once a day.

• An aluminum block with fins that makes direct contact with the CPU.

• A fan that sucks cool air from the hard drive to the CPU.

• Paste that allows for a better connection between the CPU and the fan.

Multiple Choice

A majority of CPUs use Air Cooling.

• true

• false

Multiple Choice

How does thermal compound work?

• It fills in the microscopic air gaps between CPU and Heat sink.

• It is a compound that doesn't react to heat like metal does.

• It creates a liquid barrier between the CPU and Heat Sink, allowing the system to be liquid cooled.

• It allows the CPU to be overclocked without using the BIOS.

Multiple Select

Water Cooling is better than Air Cooling in which of the following ways (check all that apply)

• It is cheaper.

• It is more efficient.

• It is quieter.

• It is better for gaming or overclocking.

• It smells better.

Poll

Did you like this way of learning?

• 100 percent, this was really good and I learned a lot.

• It was ok, but I would rather just watch the videos and take a quiz.

• I didn't like this much, there were some good parts, but most was trash.

• I hate this. Please don't ever do this again.
