Answers

1
What does CPU stand for?
Core Processing Unit
Computer Processing Unit
Central Program Unit
Central Processing Unit
2
Which part of the CPU carries out mathematical and logical operations?
Arithmetic Logic Unit (ALU)
Registers
Control Unit (CU)
Memory Unit
3
The ALU is responsible for making decisions based on logical conditions.
True
False
4
What is the function of the Control Unit (CU)?
Performs calculations
Controls the flow of data inside and outside the CPU
Connects the CPU to external devices
Stores temporary data
5
Describe the role of the Accumulator (ACC) in the CPU.
Option Red Only
Helps to reduce need for repeated memory accesses, speeding up processing.
Both Options Red and Green
stores intermediate results of calculations & operations performed by ALU
6
Registers in the CPU are slower than RAM.
False
True
7
The CPU only has one core.
False
True
8
What is the purpose of the Program Counter (PC)?
It performs logical operations
It holds data that is being transferred
It stores the current instruction being executed
It keeps track of the next instruction to be executed
9
Which of the following best describes a register?
A type of secondary storage
A part of the ALU
A type of input device
A small, fast memory location in the CPU
10
Explain how the Fetch-Decode-Execute cycle works
CPU fetches the instruction from memory (RAM) using the Program Counter.
CU interprets the instruction to understand what needs to be done.
ALU performs the operation, & the result is stored in a register or memory.
The process by which the CPU retrieves and executes instructions
