1

What is a processor?

A computer system's 'brains'

2

What are instructions executed by/in?

Cores

3

Where are cores found?

In processors

4

Name some types of core

Dual core, Quad core, Octo ocre

5

What is cache?

A small amount of temporary memory on a processor chip, very fast!

6

What does cache hold?

Commonly used instructions

7

How would doubling clock speed effect performance?

Double instructions executed per second

8

How would quadrupling cores effect the performance?

Quadruple number of instructions executed per second

9

How would an increase in cache size effect performance?

Reduces number of memory to disk transfers, so speeds up instructions executed

10

What does CPU stand for?

Central Processing Unit

11

What is another name for the CPU?

The processor

12

What cycle does the CPU follow?

Fetch - Decode - Execute

13

What kind of instructions can the CPU carry out? (2 types)

Boolean Logic and Arthithmatic

14

Where are programs and instructions stored?

In the hard drive

15

Give examples of primary memories

RAM

16

Give examples of secondary memories

Hard drives, Pen drives, USB

17

How does word size effect performance?

Processers run on binary, so 32 bit is better than 16 bit

18

How does material effect performance?

A better quality of materials can make the machine faster and more reliable

19

What is RAM?

Random Access Memory

20

What is another term for RAM?

Immediate Access Storage

21

What is clock speed measured in?

Hertz or Gigahertz

22

What's faster; RAM or Cache?

Cache

23

What is cheaper; RAM or Cache?

RAM
