Understanding the CPU and Its Functions

What does CPU stand for?

• Central Processing Operator

• Central Processing Unit

• Centralized Processing Unit

• Computer Processing Unit

What are the two main parts of the CPU?

• Arithmetic Logic Unit (ALU) and Control Unit (CU)

• Data Storage Unit (DSU) and Output Unit (OU)

• Graphics Processing Unit (GPU) and Cache Unit (CU)

• Memory Unit (MU) and Input Unit (IU)

What is the role of the Control Unit (CU)?

• The Control Unit directs the operation of the processor and manages instruction execution.

• The Control Unit is responsible for memory allocation.

• The Control Unit stores data temporarily for quick access.

• The Control Unit handles input and output operations.

Does the Control Unit execute instructions?

• Yes, the Control Unit executes instructions.

• The Control Unit partially executes instructions.

• The Control Unit executes all instructions directly.

• No, the Control Unit does not execute instructions.

What does the Arithmetic and Logic Unit (ALU) do?

• The ALU controls the flow of data between components.

• The ALU stores data in memory.

• The ALU performs arithmetic and logical operations.

• The ALU manages input and output devices.

Give an example of an arithmetic operation performed by the ALU.

• Division of two numbers

• Multiplication of two numbers

• Addition of two numbers

• Subtraction of two numbers

What are some logic functions performed by the ALU?

• MULTIPLY

• ADD

• AND, OR, NOT

• SUBTRACT

What is the four steps of the machine cycle?

• Storing, processing, and outputting

• The machine cycle consists of fetching, decoding, executing, and storing.

• Fetching, decoding, and executing only

• Inputting, processing, and displaying

List the steps involved in the machine cycle.

• Retrieve, Compute, Transfer, Finalize

• Load, Process, Output, Reset

• Input, Analyze, Display, Clear

• Fetch, Decode, Execute, Store

What does the 'fetch' step in the machine cycle involve?

• Transferring data to the output device.

• Retrieving an instruction from memory.

• Storing data in the cache memory.

• Executing an instruction in the CPU.
