Arithmetic and logical operations

External communication with input devices

Which of the following is NOT a function of the Arithmetic Logic Unit (ALU)?

Managing the CPU's power supply

Where are the results of operations performed by the ALU stored?

In the Arithmetic Logic Unit itself

Which of the following is an example of a relational operation that the ALU can perform?

Checking if one number is greater than another

What does the Memory Address Register (MAR) in the Von Neumann CPU architecture hold?

The address of the location in memory where data or an instruction is to be retrieved or stored

The data or instruction that has been retrieved from memory

The result of arithmetic and logic operations

The next instruction to execute

What is the purpose of the Memory Data Register (MDR) in the Von Neumann CPU architecture?

To hold the data or instruction that has been retrieved from memory or is about to be stored in memory

To hold the address of the location in memory where data or an instruction is to be retrieved or stored

To execute the next instruction

To perform arithmetic and logic operations

What does the Accumulator (ACC) in the Von Neumann CPU architecture hold?

The result of calculations and operations performed by the ALU

The memory location address of the next instruction

The data to be written into the memory

The instructions for the CPU to execute

What is the role of the Program Counter (PC) in the Von Neumann CPU architecture?

It holds the memory location address of the next instruction to be executed

It holds the data to be processed by the CPU

It stores the result of the CPU's calculations

It contains the actual instructions that the CPU will execute

What is the illusion created by the CPU's rapid processing of instructions?

That it is processing multiple instructions at a time

That it is processing one instruction at a time

That it is not processing any instructions

That it is processing instructions slowly

What is the role of the CPU during the execution step of the Fetch-Execute Cycle?

It performs an appropriate operation

It increments the Program Counter

It fetches the instruction from memory

When does the Fetch-Execute Cycle end?

When a HALT instruction is retrieved

After the instruction is executed

When the Program Counter is incremented

After the instruction is decoded

What is copied from the Program Counter (PC) to the Memory Address Register (MAR) during the Fetch stage of the Fetch-Execute Cycle?

The address of the next instruction

The result of the ALU operation

What happens after the address of the next instruction is copied to the MAR during the Fetch stage?

The PC is incremented to point to the next instruction

The instruction at the MAR location is executed
