1.1 Quiz - SGP

What is the primary function of the CPU?

• To manage input devices

• To execute instructions

• To store data

• To provide internet connectivity

What does the ‘fetch’ stage in the fetch-execute cycle do?

• Executes an instruction

• Retrieves an instruction from memory

• Stores data in the CPU

• Decodes an instruction

Which component is responsible for performing arithmetic and logic operations in the CPU?

• Control Unit (CU)

• Arithmetic Logic Unit (ALU)

• Cache

• Memory Address Register (MAR)

What role does the Control Unit (CU) play in the CPU?

• Performs arithmetic operations

• Executes machine learning algorithms

• Directs the operations of the CPU by interpreting instructions

• Stores instructions temporarily

Which of the following is part of the fetch-execute cycle?

• Storing

• Fetching

• Networking

• None of the above

The CPU component that temporarily holds instructions is called:

• Memory Address Register (MAR)

• Cache

• Programme Counter (PC)

What does the Memory Address Register (MAR) store?

• The instruction to be executed

• Data values used by the CPU

• The address of the memory location to be accessed

• The result of an arithmetic operation

What is the purpose of the Programme Counter (PC)?

• To keep track of the next instruction to be fetched

• To store memory addresses

• To decode instructions

• To store temporary data

The von Neumann architecture consists of which of the following registers?

• Accumulator

• Programme Counter (PC)

• Memory Data Register (MDR)

• All of the above

What is the purpose of the Accumulator in the CPU?

• Holds the results of calculations

• Holds memory addresses

• Manages cache data

• Decodes instructions
