    Explanation
    A printer is a device that can print words and pictures from a computer. It is commonly used to produce hard copies of documents or images.

    • CPU

    • Monitor

    Correct Answer
    A. Monitor
    Explanation
    A monitor is a device that displays words, videos, and pictures on a screen. It is the primary output device of a computer system, allowing users to view and interact with the information being displayed. The keyboard and mouse are input devices, allowing users to input commands and interact with the computer, while the CPU is the central processing unit responsible for executing instructions and processing data. However, none of these devices specifically display visual content on a screen like a monitor does.

    The Brain of the computer

    • Keyboard

    • Speaker

    • Processor

    • Monitor

    Correct Answer
    A. Processor
    Explanation
    The processor is often referred to as the "brain" of the computer because it is responsible for executing instructions, performing calculations, and managing data flow within the computer system. It is the central component that carries out all the necessary tasks to ensure the computer functions properly. The keyboard, speaker, and monitor are peripheral devices that provide input, output, and display capabilities, but they do not have the same level of control and processing power as the processor. Therefore, the processor is the correct answer as it plays a crucial role in the overall functioning of the computer.
