30
Q

This is the brain of the computer.

A

CPU or processor

31
Q

It interprets and carries out the basic instructions to operate a computer.

A

CPU or processor

32
Q

Nowadays, processors have multiple cores called _____?

A

Multi-core processors

33
Q

The processor is a single chips that has two or more separate processors.

A

Multi-core processors

34
Q

What are the two kinds of common multi-core processors today?

A

Dual Core Processor & Quad Core Processor

35
Q

35
Q

Consists of metal fins that draw heat away from a component.

A

Heat sink

36
Q

The fan and heat sink together are called ___?

A

Processor cooler

37
Q

Acts as temporary storage as long as the computer is running.

A

Random Access Memory (RAM)

38
Q

What are the three basic types of RAM?

A
  1. Dynamic RAM (DRAM)
  2. Static RAM (SRAM)
  3. Magnetoresistive RAM (MRAM)
39
Q

This kind of RAM needs to be recharged by the CPU. If not, it loses its contents

A

Dynamic RAM (DRAM)

40
Q

What are the many variations of DRAM?

A
  1. Synchronous DRAM (SDRAM)
  2. Double Data Rate (DDR) SDRAM
  3. DDR2 and DDR3 SDRAM
  4. Rambus DRAM (RDRAM)
40
Q

It is faster than DRAM because it is synchronized to the system clock.

A

Synchronous DRAM (SDRAM)

41
Q

It is faster than SDRAM because they transfer data twice for each clock cycle.

A

Double Data Rate (DDR) SDRAM

42
Q

It is faster than DDR SDRAM

A

DDR2 and DDR3 SDRAM

43
Q

It is a type of DRAM faster than SDRAM that uses pipelining techniques.

A

Rambus DRAM (RDRAM)

44
Q

This kind is faster and more reliable than any form of DRAM. Unlike the DRAM, this does not need to be re-energized. However, it is much more expensive and it used for special purposes.

A

Static RAM (SRAM)

45
Q

This kind stores data using magnetic charges instead of electrical charges. It has greater storage capacity, consume less power, and faster access time.

A

Magnetoresistive RAM (MRAM)

46
Q

The RAM chips are housed in a small circuit board called the ______ , which is inserted into the motherboard.

A

Memory module

47
Q

What are the three types of memory module?

A
  1. Single Inline Memory Module (SIMM)
  2. Dual Inline Memory Module (DIMM)
  3. Rambus Inline Memory Module (RIMM)
48
Q

This is a type of memory modules that has pins on opposite sides of the circuit board which connect together to form a single set of contacts. This houses SDRAM chips along with DIMMS.

A

Single Inline Memory Module (SIMM)

49
Q

This is a type of memory module that has pins on the opposite sides of the circuit board that do not connect and form two sets of contacts. This houses SDRAM chips along with SIMMs.

A

Dual Inline Memory Module

50
Q

This is a type of memory module that houses RDRAM chips.

A

Rambus Inline Memory Module (RIMM)

These are essential in avoiding the computer from overheating and maintaining a good, well-ventilated system.

A

Cooling technologies

55
Q

Also called an adapter card, is a circuit board that provides more ports than those provided by the motherboard.

A

Expansion card

56
Q

Also called a hard disk drive (HDD), is permanent storage used to hold data and programs.
