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.
