29
Q

What does LGA stand for?

A

30
Q

What are the two types of sockets on an Intel motherboard?

A

LGA 1151 (more mainstream) and LGA 2066 (higher end CPUs use this)

31
Q

What are the two types of sockets on an AMD motherboard?

A

AMA4 (similar to LGA 1151) and TR4 (similar to LGA 2066)

32
Q

What are CPU sockets?

A

The mount where a CPU connects to the motherboard.

33
Q

What are the two main manufacturer’s of CPUs?

A

Intel and AMD

34
Q

What is clock multiplying?

A

Multipliers built into the CPU that increases the speed of the CPU.

35
Q

What is overclocking?

A

When the CPU is pushed to run faster than what it was built to run.

36
Q

What is hyper-threading?

A

A pipeline within a CPU that can handle two pieces of code at the same time.

37
Q

What is a CPU core?

A

The CPU’s processor that completes tasks.

38
Q

What is a CPU cache?

A

How programs move from the hard drive into the CPU. Programs are copied from the hard drive onto RAM and then processed by the CPU very quickly. Because RAM can’t keep up with the CPU’s speed, a cache (smaller, faster memory known as SRAM) is stored inside the CPU for faster access.

39
Q

What is a pipeline stall?

A

When the piece of code the CPU needs from the cache isn’t available.

40
Q

What are the three caches that a CPU has to prevent a pipeline stall?

A

Level 1 cache (very fast). Level 2 cache (feeds the L1 cache, is bigger and runs at half speed of L1 cache). Level 3 cache (very big, runs at base motherboard speed).

41
Q

What is set association?

A

i.e. 8-way, 4-way, 12-way. Defines how the different types of caches are efficient at being able to handle the piece of code up to the CPU itself.

42
Q

What is the orientation notch?

A

Notches on the corners of the CPU used to guide installation of the CPU onto the motherboard.

43
Q

What is thermal paste and what is it used for?

A

A paste used on the CPU to pull heat away from it and into the cooling system (fan).

44
Q

What are the two benefits of a liquid cooling system?

A

It makes the computer quieter and it pulls more heat away than a fan.

45
Q

Describe a liquid cooling system and how it works.

A

It uses a pump, radiator, and a cooling block with liquid to remove heat.

46
Q

What is SDRAM?

A

Synchronous Dynamic Random Access Memory. The original, oldest type of memory that is synchronized with the clock. It has 168 pins and 2 notches.

47
Q

What is DDR SDRAM?

A

Double Data Rate Synchronous Dynamic Random Access Memory. For any given one click of a clock, DDR SDRAM gives two bits of information. It has 184 pins and a single notch.

48
Q

What is DDR2?

A

Twice as fast as DDR. It has 240 pins and a single notch.

49
Q

What is DDR3?

A

Twice as fast as DDR2. It has 240 pins and one off-set notch to ensure it not mistaken for others.

50
Q

What is DDR4?

A

Most common type of RAM and the fastest (twice as fast as DDR3). It has 288 pins and a single notch.

51
Q

What is single-sided RAM?

A

RAM that only has RAM chips on one side.

52
Q

What is double-sided RAM?

A

Commonly used RAM that has RAM chips on both sides. Not all motherboards support double-sided RAM, however.

53
Q

What does it mean when a motherboard says it has dual-channel memory?

A

Two identical RAM sticks must be put into a specific slot on the motherboard.

54
Q

What is Parity RAM?

A

RAM where one of eight of the chips can be defective and it can still run. This type of RAM contains extra chips to check for RAM errors and is mostly used for servers.

55
Q

What is ECC RAM?

A

Error Correction Code RAM. Two out of eight of the chips can be defective and it can still run. It is very expensive and contains extra chips to check for RAM errors. Mostly usually used for servers. It is only for motherboards that support it.

56
Q

What is an SPD Chip?

A

Serial Presence Detect Chip. It is built into every RAM stick (the smallest chip on the stick). Allows the system to query the RAM stick for info through software such as CPU-Z.

57
Q

What are SO-DIMMs?

A

Used for smaller spaces where longer sticks aren’t viable (such as for laptops).

58
Q

What are DIMMs?

A

Dual in-line memory module, aka a RAM stick. Comprised of a series of RAM chips on a small circuit board with pins to connect to the motherboard.

59
Q

What is BIOS?

A

Basic Input/out Services. A tiny chip on the motherboard that allows all hardware on it to be able to communicate with it.

60
Q

What is firmware?

A

Nonvolatile media that the BIOS is stored in. BIOS programs that contain code for the installed hardware to interact with the motherboard before the US loads.

61
Q

What is backup BIOS?

A

A backup of firmware.

62
Q

What is POST?

A

Power-On Self-Test. A program built into the BIOS that runs at boot, requesting devices to self check. It utilizes beep codes to alert the user what is wrong.

63
Q

What is CMOS?

A

Complementary metal-oxide-semiconductor. Small amount of memory on the motherboard that stores the BIOS settings such as date, time, and system configuration details that are needed to start the computer.

64
Q

What is a POST card?

A

Uses hexadecimal to show error codes rather than the traditional beep codes. Used to enable testing of “dead” computers (aka computers that don’t run and don’t have a beep code going off).

65
Q

What is UEFI BIOS?

A

Unified Extensible Firmware Interface. A new and improved form of BIOS (BIOS with a GUI).

66
Q

What is the system startup?

A

It is accessed on the system that the user can interact with to make changes to BIOS. It enables custom information about changeable devices and changes to CPU frequencies, RAM timings, BIOS passwords, boot options, and more.

67
Q

What is the CMOS battery?

A

Used when there is no electricity.
