Answers

1
What happens during the execution stage of the Fetch-Execute Cycle?
The operation specified by the instruction is carried out
The instruction is fetched from memory
The CPU goes into sleep mode
The instruction is written back to memory
2
What does the Memory Address Register (MAR) do?
Holds the memory location of data
All of these
Processes mathematical calculations
Stores the operating system
3
What does larger cache size do?
Improves performance by reducing cache misses
Reduces performance
All of these
Increases the CPU's clock speed
4
What are the stages of the Fetch-Execute Cycle?

5
What is the purpose of Cache Memory?
Stores instructions for the CPU
Saves all user data
Stores the operating system
Backs up the hard drive
6
What happens to data in RAM when power is off?
