CPU

Question 1

What does CPU stand for?

Answer 1

Central Processing Unit

Question 2

Is the CPU split into different parts?

Answer 2

Yes

Question 3

Name the parts the CPU is split into

Answer 3

Control Unit, ALU, Register, RAM and ROM

Question 4

What does the Control Unit do?

Answer 4

Manages execution of programs

Question 5

What does ALU stand for?

Answer 5

Arithmetic Logic Unit

Question 6

What does ALU do?

Answer 6

Performs operations like mathematical work.

Question 7

What does Registers do?

Answer 7

temporarily store items of data

Question 8

What does RAM stand for?

Answer 8

Random-Acess Memory

Question 9

what does RAM do?

Answer 9

Used to store data temporarily which can be read and written but it will lose its content once the power is switched off

Question 10

What does ROM stand for?

Answer 10

Read-Only-Memory

Question 11

What does ROM do?

Answer 11

Used to store data permanently which are important to the system and can only be read not written to.

(Operating System)

Question 12

What is “Buses” in computing terms

Answer 12

Is a set of wires used to carry data between the processor and main memory.

Question 13

Identify the different buses

Answer 13

• Address Bus
• Data Bus
• Control Bus

Question 14

Describe the Address Bus

Answer 14

It is used to specify which memory location is to be used to read or write data to

Question 15

Describe the Data Bus

Answer 15

This carries data from a memory location to the processor

Question 16

Describe the Control Bus

Answer 16

It is used to send out signals to initiate events such as write and read.

Question 17

What is an Interface?

Answer 17

An interface provides a link between a peripheral device and the CPU identifies the differences in how they operate

Question 18

Is there a difference in speed between Peripheral devices and the processor?

Answer 18

Yes because Peripheral devices operate at a much slower speed than the processor.

(Like I mentioned the CPU identifies the differences in how they operate)

Question 19

What is “Data Storage”

Answer 19

During the compensation the data may be needed into a memory location called the buffer until the peripheral data is ready to be transfer.

Question 20

What is meant by “Data Conversion”

Answer 20

Data is often stored in peripheral devices in a different format from how it is stored in the processor.
