What is the role of the Control Unit in the CPU?

• Executes arithmetic operations

• Manages and coordinates CPU activities

• Stores temporary data

• Transfers data between memory and CPU

What do registers primarily store?

• Permanent files

• Instructions and data in RAM

• Temporary data for quick access

• Operating system files

Which register keeps track of the address of the next instruction?

• Accumulator

• Memory Address Register

• Program Counter

• Control Unit

What is the function of the Memory Data Register (MDR)?

• Holds the address in memory to be accessed

• Temporarily stores data being transferred to/from memory

• Stores final calculation results

• Controls the system clock

What is the purpose of cache memory?

• To store frequently accessed instructions and data

• To permanently store programs

• To execute instructions

• To increase RAM size

The system bus consists of which three types of buses?
