Microprocessor Quiz

What is a microprocessor?

• A programmable digital circuit

• A memory module

• A storage device

• A type of software

Answer explanation

A microprocessor is a programmable digital circuit that performs computations and controls other devices. It is not a memory module, storage device, or software, making 'A programmable digital circuit' the correct choice.

What is a microcontroller?

• A storage device

• A programmable digital circuit with peripherals

• A software application

• None of the above

Answer explanation

A microcontroller is a programmable digital circuit with built-in peripherals like memory, ADC, timers, and GPIO.

What is the difference between a microprocessor and a microcontroller?

• Microprocessor has RAM and ROM built-in

• Microcontroller includes peripherals; microprocessor does not

• Microprocessor is used for control applications

• No difference

Answer explanation

The correct choice highlights that a microcontroller includes built-in peripherals (like timers and I/O ports), while a microprocessor typically does not have these integrated, requiring external components for functionality.
