    • A.

      True

    • B.

    Correct Answer
    A. True
    Explanation
    The CPU, or Central Processing Unit, is often referred to as the "brains" of the computer because it is responsible for executing instructions and performing calculations. It is the primary component that carries out the majority of the computer's processing tasks, including running programs, managing data, and controlling the overall operation of the system. Without a CPU, a computer would not be able to function or perform any tasks. Therefore, the statement that the CPU is known as the "brains" of the computer is true.

    What you see on your monitor is in:

    • A.

      Storage memory

    Correct Answer
    B. RAM memory
    Explanation
    RAM memory stands for Random Access Memory, which is a type of computer memory that is used to store data that is currently being used by the computer. It is a volatile memory, meaning that its contents are lost when the computer is powered off or restarted. The data that is stored in RAM memory is quickly accessible by the computer's processor, allowing for faster and more efficient data manipulation and execution of programs. Therefore, what you see on your monitor is stored in RAM memory.

    You can open the operating system from an icon?

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    Opening the operating system from an icon is not possible. An icon represents an application or a file, not the operating system itself. The operating system is the underlying software that manages the computer's hardware and provides a platform for running applications. To access the operating system, you need to start or boot the computer, which involves powering it on and going through the startup process. Icons on the desktop or in the taskbar typically represent applications or shortcuts to specific files or folders, not the operating system.

    Explanation
    The statement is true because a hard drive is a storage device commonly used to store documents and software on a computer. It is a non-volatile memory device that permanently stores data even when the computer is turned off. Therefore, all your documents and software can be stored on the hard drive for easy access and retrieval.
