Question 7

Where does processing occur?

Answer 7

Processing occurs in the CPU [Central Processing Unit].

Question 8

What does the acronym CPU mean?

Answer 8

CPU stands for
C: Central
P: Processing
U: Unit

Question 9

What does the output function do?

Answer 9

The output function turns the results of the processing function into a form that people or other computers can understand or use.

Question 10

What does the storage function do?

Answer 10

It saves [keeps] information ready/accesible for the CPU to use.

Question 11

What are the two formats that information can be stored as.

Answer 11

It can be stored either magnetically or electronically.

Question 12

What is the CPU?

Answer 12

The central processing unit is the hardware component of a computer system where processing occurs.

Question 13

What is Hardware?

Answer 13

Hardware is a general term for all pieces of equipment in a computer system that you can touch or carry?

Question 14

Give an example for each type of function of the computer: Input, Processing, Storage and Output

Answer 14

Input: Mouse
Processing: CPU
Output: Screen
Storage: Disk

Question 15

How can you classify Hardware?

Answer 15

Hardware is classified based on the four basic functions of the computer system: IPOS

Input, Processing, Output and Storage.

Question 16

What are some hardware devices according to the four basic functions.

Answer 16

Input: Keyboard
Processing: Processor/CPU
Output: Speaker System
Storage: Flash Drive

Question 17

What are the four basic functions?

Answer 17

The four basic functions are IPOS.

Question 18

What is the modern-day terminology for the processor?

Answer 18

The modern-day terminology for the process is the CPU.

Question 19

What are peripherals and give examples.

Answer 19

Peripherals are devices that are connected to the core computer.

Input, Output and Storage Devices are considered peripherals.

Question 20

What is the major component of the computer system?

Answer 20

The major component is the CPU.

Question 21

What is inside a processor?

Answer 21

There are several electronic components inside the CPU, they are the [CAM]:

1. Control Unit
2. Arithmetic and Logic Unit [ALU]
3. Main Memory [IAS] Immediate Access Storage

Question 22

Why is it emphasized that all components in the CPU are electronic?

Answer 22

Because without power these components will stop working.

They require power to work.

Question 23

What does the Control Unit do?

Answer 23

The control unit passes instructions to the different parts of the processor/CPU.

WHY?: So the process can carry out the correct tasks in the right order.

Question 24

What does the [ALU] Arithmetic and Logic Unit do?

Answer 24

The ALU performs calculations and transforms data at lightning speed.

Question 25

What does the Immediate Access Storage [Main Memory] do?

Answer 25

The Immediate Access Storage/Main Memory stores all the information that is being processed by the [ALU] Arithmetic and Logic Unit.

Question 26

Where do all these components stay?

Answer 26

These components are usually fixed to the motherboard, which has connections to the peripherals. [IPOS]

Question 27

What joins these electronic components together?

Answer 27

They are joined together by connections called data.

“The connection of data.”
