Alsager - A2 - 1.1.1 - Characteristics of Contemporary Processor

Which of the following is NOT a component of the Central Processing Unit (CPU)?

• Arithmetic and Logic Unit

• Control Unit

• Data Bus

• Memory Address Register

What is the role of the Program Counter in a CPU?

• It holds the data that is being transferred to and from the immediate access store.

• It determines the sequence of operations in which instructions are executed.

• It holds the address of the next instruction to be executed.

• It stores the results of arithmetic and logic operations.

Which of the following is a factor that affects the performance of the CPU?

• The size of the hard disk

• The resolution of the monitor

• The speed of the graphics card

• The clock speed of the CPU

What is the Fetch-Decode-Execute Cycle?

• A process that relates to assembly language programs

• A cycle that improves the efficiency of the processor through pipelining

• The cycle that a CPU goes through to execute an instruction

• A method of comparing different CPU architectures

Which architecture uses a shared memory space for program instructions and data?

• Von Neumann architecture

• Harvard architecture

• Contemporary processor architecture

• Distributed architecture

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

• It directs the operations of the CPU.

• It completes all of the arithmetical and logical operations.

• It stores the resulting data back in memory.

• It manages the flow of data between the CPU and other devices.

What are the main jobs of the Control Unit?

• Completing arithmetical and logical operations.

• Temporarily storing data and all arithmetic, logical and shift operations.

• Directing the operations of the CPU, managing data flow, accepting and decoding instructions, and storing data back in memory.

• Holding the address of the next instruction to be executed.

What is the purpose of registers in a processor?

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

• To store the results from calculations.

• To temporarily store data and all arithmetic, logical and shift operations.

• To hold the current instruction being executed.

What does the Program Counter (PC) register do?

• Stores the results from calculations.

• Holds the address of a location that is to be read from or written to.

• Temporarily stores data that has been read or data that needs to be written.

• Holds the address of the next instruction to be executed.

What is stored in the Accumulator (ACC) register?

• The address of the next instruction to be executed.

• The results from calculations.

• The address of a location that is to be read from or written to.

• The current instruction being executed.
