Understanding CPU Components

What is the primary role of the CPU in a computer system?

• To process input and produce output

• To store data permanently

• To manage network connections

• To provide power to the system

Which component of the CPU is responsible for coordinating all activities?

• Control Unit

• Memory Data Register

• Arithmetic Logic Unit

• Program Counter

What does the Program Counter hold?

• The address of the next instruction

• The current instruction being executed

• The status of the CPU

• The result of the last calculation

What is the function of the Memory Data Register?

• To store the address of the next instruction

• To temporarily hold data being transferred to or from memory

• To execute arithmetic operations

• To manage control signals

Which component performs arithmetic and logical operations?

• Program Counter

• Control Unit

• Arithmetic Logic Unit

• Memory Address Register

What is the role of the address bus in a CPU?

• To carry data between the CPU and memory

• To carry memory addresses from the CPU to memory

• To manage control signals

• To store temporary data

Which bus is responsible for carrying binary data?

• Memory Bus

• Control Bus

• Data Bus

• Address Bus

What is the function of the decode unit in a CPU?

• To interpret and prepare instructions for execution

• To execute instructions

• To manage power supply

• To store frequently used data

What does the clock in a CPU do?

• Stores data permanently

• Provides power to the system

• Synchronizes components by generating pulses

• Manages network connections

What is the purpose of cache in a CPU?

• To provide fast access to frequently used data

• To store the operating system

• To manage input/output devices

• To execute complex calculations
