What is the function of the central processing unit (CPU)?

• . Interprets and executes commands from computer hardware and software.

• Controls input and output devices.

• Carries out calculations and makes logical decisions.

• Manages the engine system in a car.

What is the modern term for CPUs

• Discrete components.

• Numerous small integrated circuits.

• Microprocessors

• Circuit boards.

What is a microprocessor?

• A part of the computer motherboard.

• A single integrated circuit at the heart of most PCs.

• A control unit that manages input and output devices.

• Small memory locations called registers

What is an arithmetic and logic unit (ALU)?

• A part of the computer motherboard.

• A single integrated circuit at the heart of most PCs

• A control unit that manages input and output devices.

• A component that carries out calculations and makes logical decisions.

What are registers?

• Small memory locations that store data temporarily.

• Integrated circuits that make up CPUs.

What is the purpose of Random Access Memory (RAM)?

• To temporarily store data when running applications

• To control input and output devices

• To carry out calculations and make logical decisions.

• To store information permanently.

What happens to the contents of RAM when power to the computer is turned off

• They are permanently stored.

• They are lost

• They are read-only.

• They are altered

What is Read-only memory (ROM) used for?

• To store temporary data.

• To control input and output devices.

• To contain configuration data for a computer system

• To carry out calculations and make logical decisions.

Can chips used for ROM be altered?

• Yes, they can be altered.

• No, they cannot be altered

• Yes, but only once.

What is the main advantage of ROM?

• It is volatile memory.

• It can be altered easily.

• It stores information permanently.

• It is lost when power is turned off.
