What is a Microprocessor?
Correct Answer
A. A component that needs instructions
Explanation
A microprocessor is a component that needs instructions. It is a small electronic device that functions as the central processing unit (CPU) of a computer. It is responsible for executing instructions and performing calculations, making it an essential component in any computer system. Without instructions, a microprocessor would be unable to carry out any tasks or functions. Therefore, it is accurate to describe a microprocessor as a component that needs instructions.

True/false, Does a kettle have a Microprocessor Inside it?
Correct Answer
B. False
Explanation
A kettle is a simple appliance used for heating water and does not require complex functions or calculations that would necessitate the use of a microprocessor. It typically consists of a heating element, a switch, and a thermostat to control the temperature. Therefore, it is unlikely to have a microprocessor inside it.
8.
A touchscreen is a output device and input device.
Correct Answer
A. True
Explanation
A touchscreen can be considered both an input and output device because it allows users to interact with the device by touching the screen, which is an input action. It also displays information and visuals on the screen, which is an output action. Therefore, a touchscreen serves the purpose of both input and output, making the statement true.
9.
What does CPU stand for?
Correct Answer
B. Central Processing Unit
Explanation
The correct answer is "Central Processing Unit." The CPU is the main component of a computer that performs most of the processing inside the computer.

11.
What does PSU stand for?
Correct Answer
B. Power Supply Unit
Explanation
The correct answer is Power Supply Unit. PSU stands for Power Supply Unit, which is a hardware component that provides electrical power to a computer or other electronic devices. It converts the AC power from the wall outlet into DC power that is suitable for the computer's internal components. This is an essential component for the proper functioning of a computer system.
12.
True/false, Does a computer need a power supply unit?
Correct Answer
A. True
Explanation
A computer requires a power supply unit (PSU) in order to function. The PSU is responsible for converting the alternating current (AC) from the electrical outlet into direct current (DC) that the computer components can utilize. It supplies power to the motherboard, CPU, graphics card, and other hardware components. Without a PSU, the computer would not receive the necessary power to operate. Therefore, the statement "True" is correct.
