The invention of the microprocessor

The development of the first graphical user interface

Who is credited with the idea of the stored-program computer?

John von Neumann and his colleagues

How does the CPU access the program instructions and data in the Von Neumann architecture?

Through separate buses for instructions and data

Control Unit and Arithmetic-Logic Unit

Arithmetic-Logic Unit and Cache

Which of the following is true about the cache in relation to the CPU?

Cache is slower than RAM but faster than registers

Cache is faster than both RAM and registers

Cache is slower than both RAM and registers

Cache is faster than registers but slower than RAM

What does the Program Counter (PC) in the CPU hold?

The address of the next instruction to be executed

The result of an instruction before it is transferred to memory

The actual instruction and the data that has been fetched from memory

The memory address of the current instruction, and then the data that it uses

What is the purpose of the Memory Address Register (MAR) in the CPU?

It holds the memory address of the current instruction, and then the data that it uses, so that these can be fetched from memory

It holds the result of an instruction before it is transferred to memory

It holds the address of the next instruction to be executed

It holds the actual instruction, and then the data that has been fetched from memory

What does the Memory Data Register (MDR) contain?

The actual instruction, and then the data that has been fetched from memory

The address of the next instruction to be executed

The memory address of the current instruction

The result of an instruction before it is transferred to memory

What is stored in the Accumulator within the CPU?

The result of an instruction before it is transferred to memory

The memory address of the current instruction

The address of the next instruction to be executed

The actual instruction and the data that has been fetched from memory

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

It coordinates and controls all of the activities taking place within the CPU.

It performs arithmetic operations.

It stores data temporarily for quick access.

It connects the CPU to external devices.

What does the control unit do with the instructions it receives?

It decodes instructions and executes them.

It sends the instructions to the printer.

It stores the instructions in the hard drive.

It converts the instructions into audio signals.

What is the primary function of the Arithmetic Logic Unit (ALU) in a CPU?

To perform arithmetic and logical operations

To manage the computer's memory

To control input and output devices

What does the CPU do during the DECODE operation in the Fetch-Decode-Execute cycle?

It saves the instruction for later use.

It fetches the instruction from main memory.

How does the CPU operation cycle continue after executing an instruction?

The CPU goes into a sleep mode.

The CPU performs a system check.

What is the role of the Program Counter (PC) in a CPU?

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

It stores the data that is currently being processed.

It performs arithmetic and logical operations.

It manages the input/output operations of the computer.

When is the Program Counter incremented?

As soon as the instruction has been fetched.

After the instruction has been executed.

Before the instruction is fetched.

What is the function of the accumulator (ACC) in the CPU architecture?

It temporarily stores arithmetic and logic results.

It permanently stores user data.

It is used to increase the speed of the CPU.

It manages the communication between the CPU and peripherals.
