Which part of the computer fetches the next instruction during the fetch-execute cycle

The part of the computer that fetches the next instruction during the fetch-execute cycle is the Control Unit. The Control Unit is a component of the Central Processing Unit (CPU) and it manages the data flow within the system. Here are the steps it follows:

1. Fetch: The Control Unit fetches the instruction from the memory. It uses the Program Counter to keep track of the memory address of the next instruction that needs to be fetched.

2. Decode: Once the instruction is fetched, it needs to be decoded or interpreted. The Control Unit decodes the instruction to determine what action needs to be taken.

3. Execute: After the instruction is decoded, the Control Unit sends signals to the appropriate part of the computer to execute the instruction.

4. Store: Once the instruction is executed, the results are stored back in the memory.

This cycle repeats for each instruction until the program is complete.

The part of the computer that fetches the next instruction during the fetch-execute cycle is the Control Unit. The Control Unit is a component of the Central Processing Unit (CPU), and it manages the execution of instructions by the computer.

Here are the steps involved in the fetch-execute cycle:

1. Fetch: The Control Unit fetches the instruction from the memory. This is done by sending the address of the instruction to the memory, and then retrieving the instruction.

2. Decode: The Control Unit decodes the instruction to determine what operation needs to be performed.

3. Execute: The Control Unit executes the instruction. This could involve performing a calculation, moving data from one location to another, or performing some other operation.

4. Store: The results of the operation are stored in the memory.

5. The Control Unit then fetches the next instruction, and the cycle repeats.

This cycle continues until the computer is powered off or until it is instructed to stop.
