A-Level Processor Architecture and Storage

What is the primary role of the ALU (Arithmetic and Logic Unit) in a processor?

• Managing program execution

• Performing arithmetic and logic operations

• Storing data temporarily

• Controlling the clock speed

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

• MAR (Memory Address Register)

• MDR (Memory Data Register)

• PC (Program Counter)

• ACC (Accumulator)

What is the purpose of the control unit in the CPU?

• Performing calculations

• Controlling data transfer between registers

• Managing and interpreting instructions

• Storing frequently used data

Which type of bus is responsible for transferring instructions and data to and from memory?

• Control Bus

• Address Bus

• Data Bus

• Power Bus

During the fetch-decode-execute cycle, which register is updated after fetching the next instruction?

• ACC

• MAR

• PC

• CIR

Which factor improves CPU performance by allowing simultaneous execution of instructions?

• Cache memory

• Clock speed

• Number of cores

• Pipelining

Which architecture uses a single memory for both data and instructions?

• Harvard

• Von Neumann

• Contemporary

• Parallel

Which statement correctly describes a RISC processor?

• It has fewer instructions with simple operations.

• It has a large instruction set with complex operations.

• It is only used in graphics processing.

• It cannot perform pipelining.

What is a key advantage of CISC processors over RISC processors?

• Lower power consumption

• Faster clock speed

• Ability to perform complex instructions in a single cycle

• Simpler design

What is a primary use of GPUs outside graphics processing?

• Managing input/output operations

• Running simple scripts

• Accelerating data processing in machine learning

• Handling network requests
