What is the primary function of a CPU?

• Performing input/output operations

• Executing instructions and performing calculations

• Storing data for long-term use

• Managing user interface operations

In the CPU, which unit is responsible for executing arithmetic and logical operations?

• Control Unit (CU)

• Arithmetic Logic Unit (ALU)

• Memory Unit

• Load, Fetch, Decode

• Decode, Execute, Load

What is the role of registers in a CPU?

• Storing data temporarily during execution

• Storing permanent data

• Managing input/output operations

• Controlling the program flow

Which type of memory is used by the CPU to store frequently accessed data and instructions?

• Hard Drive

• RAM

• Cache

• ROM

What happens during the 'fetch' phase of the CPU's instruction cycle?

• The CPU retrieves data from the hard drive

• The CPU fetches an instruction from memory

• The CPU decodes the instruction

• The CPU stores the result

During the 'decode' phase, what does the CPU do?

• The CPU reads data from input devices

• The CPU translates the instruction into signals for execution

• The CPU writes data to memory

• The CPU increments the program counter

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

• It manages memory operations

• It performs arithmetic and logical calculations

• It controls peripheral devices

• It stores program instructions

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

• To store the result of operations

• To manage input/output operations

• To keep track of the next instruction to execute

• To decode instructions
