Question 9

Processing and executing instructions:

Answer 9

●Fetch
●Decode
●Execute

Question 10

Managing System Resources:

Answer 10

●Input/output devices
●Memory management
●Interrupt handling

Question 11

Refers to how fast a CPU can execute instructions, measured in Hertz (Hz). Modern processors usually operate in Gigahertz (GHz), meaning billions of cycles per second.

Answer 11

Clock speed

●Memory Management Unit
●Register

Question 15

Responsible for managing data flow and the execution of instructions within the computer system

Answer 15

Control Unit

Question 16

What cycle does the Control Unit use to manage data flow.

Answer 16

Fetch-decode-execute cycle

Question 17

It executes calculations using binary numbers and manipulates them using logic gates.
It receives data from registers within the CPU

Answer 17

Arithmetic Logic Unit (ALU)

Question 18

These components handle memory-related tasks, such as managing the CPU and RAM interaction.

Answer 18

Memory Management Unit

Question 19

These are small, high speed memory storage locations within the CPU. They hold data that the CPU is currently working on and facilitate quick access data.

Answer 19

Register

Question 20

It provide faster access times than other memory levels like RAM or cache memory
Quicker than cache memory but limited storage, typically measured in kilobytes.

Answer 20

Register
