Q

What is beneficial about a ZIF socket?

A

It means you can insert the CPU without applying pressure, which means you are less likely to break pins and therefore break the processor.

Q

Describe how an LGA socket works.

A

There are flat metal contacts on the underside of the chip instead of pins, which rest on the corresponding contacts of the socket. There is often a brace to help hold it in and small notches to help with alignment.

Q

Describe how a PGA form factor works.

A

Pins on the underside of the chip fit into holes in the socket, and pressure then needs to be applied to fully insert the chip

Q

Describe how simultaneous multithreading/Hyper-threading works.

A

A single stream of instructions is being sent by a software application to a processor; the CPU splits each physical core into two virtual cores.

22
Q

What is the difference between a multi-processor and a multi-core system?

A

Multi-processor would have more than one CPU, multi-core refers to how many cores within the single CPU

23
Q

How does symmetric multiprocessing work?

A

Where multiple processors share a common OS and memory.

24
Q

Why should you always use hyper-threading with multi-core processors?

A

Because there will always be idle cycles, and hyper-threading takes advantage of that for a greater overall throughput

25
Q

How is a multi-core processor beneficial?

A

It allows for more threads to be worked on at once, therefore resulting in greater throughput.

26
Q

What is virtualisation?

A

Allowing multiple systems to run on a single physical host

27
Q

What do VT and AMD-V do?

A

They are hardware extensions to support virtualisation

28
Q

What is SLAT (Second Level Address Translation)?

A

Features of software virtualisation are underlying and supported by the hardware processor.

29
Q

Compare and contrast AMD and Intel CPUs.

A

AMD: Generally less expensive, more popular with gamers/hobbyists, tends to outperform Intel in regards to graphics, generally better at handling 64-bit applications
Intel: Have a faster overall processing speed, don’t run as hot, better compatibility, pull slightly more power and cost more

30
Q

What is the Architecture State (AS)?

A

A monitoring component that checks for idle cycles and informs the processor to direct attention to the other threads

31
Q

How does a single core CPU process threads?

A

By working on one at a time and cycling through them, giving attention to each but for a limited amount of time.

32
Q

List the steps required to install the motherboard and CPU.

A
  1. Review the motherboard’s documentation
  2. Place the motherboard aligned at the rear of the case
  3. Insert standoffs that match the hole in the motherboard
  4. Install the processor and memory modules before installing the motherboard
  5. Verify the standoffs are properly aligned prior to installing the motherboard
  6. Secure the standoffs using the appropriate screw type
  7. Install the power supply, disk drives, and add-on cards
33
Q

What is the PCIe x1 card used for?

A

Modems, network cards, wireless cards, input/output devices and audio cards

34
Q

What is the max bus speed a PCI 32-bit card can support?

A

33MHz or 133 MBps

35
Q

How many bits is the PCI-X card?

38
Q

What is the AGP (Accelerated Graphics Port) used for?

A

Video graphics cards: AGP 1x, 2x, 4x and 8x

39

It replaces PCI, PCI-X, and AGP
There are 4 versions: x1, x4, x8 and x16

40
Q

What is PCIe x16 used for?

A

Graphics and video cards (including 3D)
Gaming systems

41
Q

Which two PCIe versions maximise the number of lanes used on a motherboard?

A

PCIe x1 and x16

42
Q

How does a PCIe card work?

A

It connects to the bus to transfer data to and from the motherboard and external devices. The bus is determined by the motherboard and its form factor (16, 24 or 32 PCIe lanes)

43
Q

How many watts of power do PCIe slots provide?
What about PCIe x16?

A

25w
up to 75w

44
Q

What do up-plugging and down-plugging mean?

A

Putting a smaller card in a larger slot, and putting a larger card in a smaller slot

45
Q

Where are mini PCIe cards normally used?

A

Inside laptops, specifically for wireless networking

46
Q

What does a VCC (Video Capture Card) do?

A

Takes video signals and processes them inside the computer; often used for recording footage and security devices

47
Q

What does a Video Card/Graphic Adapter do?

A

Gives quality signal for monitors

48
Q

What is the name for the specialised processor designed to accelerate graphics rendering?

A

Graphics Processing Unit (GPU)

49
Q

Give some examples of graphical ports. Where are they installed?

A

Thunderbolt, DisplayPort and HDMI; they are installed outside of the card

50
Q

How does a TV Capture Card work?

A

Cables are plugged into a computer to get all cable TV channels

51
Q

What is the only required connector for a NIC (Network Interface Card)?

A

RJ45 connector

52
Q

What connectors support a fiber card?

A

ST, SC, MT-RJ

53
Q

What is a riser card?

A

A special type of expansion card on a motherboard

54
Q

What type of cards likely have multiple HDMI and/or DisplayPort connections?

A

Video cards
