Q

What does CPU stand for and what does it do?

A

Central processing unit, processes all of the input data output, essentially the brain of the computer

2
Q

When describing CPU what nomenclature should you use?

A

Make and model. Make: Intel model: i73820

3
Q

What defines the difference between CPUs

A

The microarchitecture.

4
Q

What is one hertz?

A

One cycle per second

5
Q

What makes the CPU go?

A

The system crystal that oscillates at a certain speed on the motherboard. A.k.a. motherboard speed

6
Q

If the system Crystal can only oscillate at a certain speed how does the CPU go faster?

A

There is a clock multiplier inside the CPU.

7
Q

What is the CPU speed calculated in?

A

Hertz

8
Q

So how is final CPU speed determined?

A

Speed of the motherboard and the clock multiplier

9
Q

What is a multicore processor?

A

They include more than one CPU on a single physical chip

10
Q

What is hyper threading?

A

The ability to make 1 core look like 2, only for Intel.

11
Q

What is a cache?

A

Very fast temporary storage on a cpu. It helps with the overall speed of the computer.

12
Q

What is the benefit of small cache?

A

It’s faster

13
Q

What is the benefit of bigger cache?

A

It can hold more data.

14
Q

What is the level one cache?

A

The cache that is physically closest to the CPU. Generally smaller and faster.

15
Q

What is the difference between a level one and level two cache?

A

Level two is bigger and slower usually half the speed of level one.

16
Q

What is the difference in 32-bit and 64-bit processors?

A

64-bit can handle more ram

17
Q

What is GPU?

A

Integrated graphics processing unit. video card that is built into the CPU itself used by Intel.

18
Q

What do the CPU extensions do?

A

They add functionality to a processor.

19
Q

What is virtualization support?

A

Enables CPUs to more efficiently run virtualized systems

20
Q

What are the types of CPU sockets?

A

LGA & PGA

21
Q

What does PGA stand for

A

Pin grid array socket. Mainly used by AMD

22
Q

What is a zif socket

A

Zero insertion force

23
Q

What does LGA stand for?

A

Land grid array, used by Intel

24
Q

What are the characteristics of LGA 775?

A

775 lands, First mainstream CPU to use LGA, runs with ddr2, started with pentium 4 and lasted through core 2’s.

25
Q

What are the characteristics of LGA 1156?

A

More mainstream systems, 1156 lands, first socket to have a built in North bridge and ddr3 support, core i3, i5, i7.

26
Q

What are the characteristics of LGA 1366?

A

For higher end systems, 1366 lands, built in memory controller to talk to ram, could support lots of DDR3, core i7

27
Q

What are characteristics of LGA 1155?

A

Replaced the 1156, was the first to have full support of onboard graphics. Core i3 i5 i7

28
Q

What are the characteristics of the LGA2011?

A

Started with DDR3 went to DDR4, supported the first systems to stop using PCI. Only pci express

29
Q

What are the characteristics of LGA 1150

A

Sports multiple CPUs, started with DDR3 and supports DDR four and supports lots of PCI E devices
