    Explanation
    The CPU, or Central Processing Unit, is often referred to as the 'brain' of the computer. This is because it performs most of the processing inside the computer. Just like our brains allow us to think, make decisions, and process information, the CPU handles instructions from programs and apps, processes data, and manages tasks efficiently. It's essential for running software and executing commands, making it critical for the computer's overall operation. Other devices like monitors, keyboards, and mice serve different functions like displaying information, inputting data, and controlling the computer's interface.

It works by converting physical documents or images into digital format, allowing them to be stored, edited, or transmitted electronically. Unlike a keyboard, microphone, or mouse, which primarily capture input in the form of text, sound, or movement respectively, a scanner specifically focuses on capturing visual information and converting it into digital data that can be processed by the computer.

    A monitor is an example of an output device. It displays information and visuals generated by the computer, such as windows, apps, videos, and games. Essentially, it shows the results of the computer’s computations and user inputs. This makes it crucial for interacting with the computer as it allows users to see what the machine is doing. Unlike input devices like a scanner, which captures images and text into the computer, or a keyboard and microphone, which are used to input data and sound, a monitor's sole function is to output digital content visually.

    • Keyboard

    • Mouse

    • Joystick

    Correct Answer
    A. Keyboard
    Explanation
    A keyboard is not considered a pointing device because it is primarily used for inputting text and commands, rather than directly controlling the cursor or selecting objects on the screen. Pointing devices, such as a mouse, joystick, or light pen, are specifically designed to move the cursor and interact with graphical user interfaces. While a keyboard can indirectly control the cursor by using arrow keys or shortcuts, it is not classified as a pointing device in the traditional sense.

These options allow users to manipulate and transfer text or other data within the application. The "file" menu usually contains options related to saving, opening, and printing files, while the "view" menu typically offers options to customize the appearance of the application's interface. Therefore, the correct answer is "edit" as it is the menu where cut, copy, and paste options are commonly found.
