Mock P1...Revise CPU

Which component of the CPU is responsible for performing arithmetic and logical operations?

• Control Unit (CU)

• Arithmetic Logic Unit (ALU)

• Register

• Cache

What is the primary function of the Control Unit (CU) in a CPU?

• To store data temporarily

• To perform calculations

• To decode instructions and control the flow of data

• To increase clock speed

Which register holds the address of the next instruction to be executed?

• Accumulator (ACC)

• Memory Address Register (MAR)

• Program Counter (PC)

• Memory Data Register (MDR)

What is the purpose of the Accumulator (ACC) in a CPU?

• To store the result of arithmetic and logic operations

• To hold the address of the next instruction

• To store data fetched from memory

• To manage the control signals

Which type of cache memory is closest to the CPU core?

• L1 Cache

• L2 Cache

• L3 Cache

• Main Memory

How does having multiple cores in a CPU benefit performance?

• Increases the clock speed

• Allows for parallel processing of tasks

• Reduces the need for cache memory

• Decreases power consumption

What is the role of the clock speed in a CPU?

• Determines the size of the cache

• Controls the number of instructions executed per second

• Increases the number of cores

• Reduces the power usage

During which stage of the Fetch-Decode-Execute cycle is the instruction translated into signals?

• Fetch

• Decode

• Execute

• Store

What happens during the 'Fetch' stage of the Fetch-Decode-Execute cycle?

• The CPU executes the instruction

• The CPU fetches the instruction from main memory, RAM

• The CPU decodes the instruction

• The CPU stores the result

Which of the following is NOT a factor that affects CPU performance?

• Number of cores

• Clock speed

• Amount of RAM

• Cache size
