Understanding the Fetch-Execute Cycle

What are the three main stages of the fetch-decode-execute cycle?

• Fetch, Analyse, Execute

• Fetch, Decode, Execute

• Fetch, Compile, Execute

• Fetch, Interpret, Execute

Which of the following best describes the fetch stage of the fetch-decode-execute cycle?

• The processor carries out the instruction.

• The processor retrieves an instruction from memory.

• The processor translates the instruction into machine code.

• The processor stores the result of the instruction.

During the decode stage, what does the processor do?

• It executes the instruction.

• It fetches the next instruction.

• It translates the instruction into signals.

• It stores the instruction in memory.

What happens during the execute stage of the fetch-decode-execute cycle?

• The instruction is fetched from memory.

• The instruction is decoded into signals.

• The instruction is carried out by the processor.

• The instruction is stored for later use.

Which type of software does the fetch-decode-execute cycle apply to?

• Only application software

• Only system software

• Both application and system software

• Neither application nor system software

Before the fetch-decode-execute cycle can begin, what must be true about a program's instructions?

• They must be compiled into machine code.

• They must be ready to be carried out.

• They must be stored in the cloud.

• They must be written in a high-level language.

Which of the following is NOT a part of the fetch-decode-execute cycle?

• Fetch

• Decode

• Compile

• Execute

How often is the fetch-decode-execute cycle repeated?

• Once per program

• Once per instruction

• Once per second

• Once per minute

What is the primary purpose of the fetch-decode-execute cycle?

• To compile programs into machine code

• To execute instructions in a program

• To store data in memory

• To debug programs

Which of the following operations would involve the fetch-decode-execute cycle?

• Playing a video game

• Filling in a spreadsheet

• Debugging a program

• All of the above
