1.1.1 Structure and function of the processor

What is the purpose of the Arithmetic and Logic Unit (ALU)?

• To control and coordinate the activities of the CPU

• To store the results from calculations

• To complete all arithmetical and logical operations

• To temporarily store data

What is the role of the Control Unit in a processor?

• To control and coordinate the activities of the CPU

• To store the results from calculations

• To complete all arithmetical and logical operations

• To temporarily store data

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

• Program Counter (PC)

• Accumulator (ACC)

• Memory Address Register (MAR)

• Memory Data Register (MDR)

What is the purpose of the data bus in a CPU?

• To transport data and instructions between components

• To transmit memory addresses

• To transmit control signals

• To synchronize operations

Which bus is used to transmit the memory addresses?

• Data Bus

• Address Bus

• Control Bus

• Clock

What is the purpose of assembly language?

• To represent machine code using mnemonics

• To execute arithmetic and logical operations

• To store data temporarily

• To coordinate the activities of the CPU

What is the main goal of pipelining in a processor?

• To reduce the amount of idle CPU time

• To increase clock speed

• To improve cache memory performance

• To optimize the size of individual memory cells

What are the factors that affect CPU performance?

• Clock speed, number of cores, and cache memory

• Control unit, ALU, and registers

• Data bus, address bus, and control bus

• Fetch, decode, and execute cycles

What is the purpose of cache memory in a CPU?

• To hold the address of the next instruction to be executed

• To store the results from calculations

• To temporarily store data that has been read or needs to be written

• To copy instructions fetched from main memory for quicker access

Which architecture uses a shared memory and shared data bus for both data and instructions?

• Von Neumann Architecture

• Harvard Architecture

• Contemporary Processing

• None of the above
