What is the main function of the CPU?

• To store large amounts of data permanently

• To process data and execute instructions

• To display graphics on the screen

• To manage external devices

Which of the following is NOT a component of the CPU?

• Control Unit

• Arithmetic Logic Unit

• Hard Drive

• Registers

What is the primary role of the ALU?

• Fetching instructions from memory

• Performing arithmetic and logical operations

• Managing the execution of programs

• Controlling data flow between components

The Control Unit is responsible for:

• Executing calculations and logic operations

• Storing frequently accessed data

• Coordinating the activities of the CPU

• Holding memory addresses for instructions

Which memory component in the CPU is the fastest but has the smallest storage capacity?

• RAM

• Hard Drive

• Cache

• Optical Disc

What is the purpose of registers in the CPU?

• To store data permanently

• To temporarily hold data and instructions

• To communicate with external devices

• To store large files for future use

The Von Neumann architecture is based on the idea that:

• Data and instructions are stored separately

• Data and instructions share the same memory

• Instructions are executed in parallel

• Multiple CPUs are used for processing

What does the Program Counter (PC) store?

• The result of the last operation

• The next instruction to be executed

• The memory address of the last used data

• The control signals for the CPU

What does the Memory Address Register (MAR) do?

• Stores data being processed

• Holds the address of data or instructions being accessed

• Controls the execution of programs

• Stores frequently used instructions

The Memory Data Register (MDR) is used to:

• Hold data being transferred to or from memory

• Store instructions permanently

• Keep track of executed instructions

• Control the execution of instructions
