  • 3. 

     The computer device most widely used: 

    • A.

      External Option

    • B.

      Mouse

    • C.

      Internal Hard Disk

    • D.

      Monitor

    Correct Answer
    C. Internal Hard Disk
    Explanation
    The internal hard disk is the correct answer because it is a crucial component of a computer system that stores all the data, software, and operating system. It is responsible for the long-term storage of files and programs, allowing the computer to access and retrieve data quickly. Without an internal hard disk, a computer would not be able to function properly or store any data. The mouse and monitor are peripheral devices that enhance the user's interaction with the computer, but they are not as essential or widely used as the internal hard disk.

    RAM means...

    • A.

      Raid act memory

    • B.

      Random access memory

    • C.

      Read only memory

    • D.

      Read access memory

    Correct Answer
    B. Random access memory
    Explanation
    RAM stands for Random Access Memory. It is a type of computer memory that allows data to be read from or written to in any order, regardless of the physical location of the data. This means that the computer can access any piece of data stored in RAM directly, without having to search through the entire memory. RAM is a volatile memory, which means that its contents are lost when the computer is turned off or restarted. It is used by the computer's operating system and applications to store data that is being actively used, providing fast and temporary storage for the computer's processes.

    What Program can cause harmful to computer operation?

    • A.

      Fortran

    • B.

      C-language

    • C.

      Virus

    • D.

      None

    Correct Answer
    C. Virus
    Explanation
    A virus is a program that can cause harm to computer operations. Unlike Fortran and C-language, which are programming languages used to write computer programs, a virus is specifically designed to disrupt or damage the normal functioning of a computer system. Viruses can infect files, spread across networks, and perform malicious activities, such as deleting files, corrupting data, or stealing sensitive information. Therefore, a virus is the correct answer as it poses a direct threat to computer operations.

    Rom is which type of memory…..

    • A.

      Non-volatile

    • B.

      Volatile

    • C.

      Dynamic

    • D.

      Static

    Correct Answer
    A. Non-volatile
    Explanation
    ROM (Read-Only Memory) is a type of memory that retains its data even when the power supply is turned off. Non-volatile memory refers to a type of memory that retains its data even without a power supply, making it the correct answer for the question. Volatile memory, on the other hand, requires a continuous power supply to retain its data. Dynamic and static are types of RAM (Random Access Memory) and are not relevant to the question.
