    • Random Only Memory

    • Read Only Memory

    • Read  Only Management

    Correct Answer
    A. Read Only Memory
    Explanation
    ROM stands for Read Only Memory. It is a type of computer memory that stores data permanently and cannot be modified or erased by normal computer operations. It contains instructions that are permanently written during manufacturing and remains intact even when the computer is powered off. Unlike Random Access Memory (RAM), which is volatile and temporary, ROM retains its data even without power. Therefore, the correct answer is Read Only Memory.

    Correct Answer
    A. Input Device
    Explanation
    A joystick is classified as an input device because it allows the user to provide input to a computer or electronic device. It is typically used to control the movement or direction of a cursor, character, or object on a screen. The joystick translates physical movements or actions into digital signals that can be interpreted by the device. This makes it an essential tool for gaming, flight simulation, and other applications where precise control and input are required.

    • Option 4

    Correct Answer
    A. RAM
    Explanation
    RAM stands for Random Access Memory. It is a type of computer memory that is responsible for temporarily storing data that is being actively used by the computer's operating system, software, and applications. Unlike ROM (Read-Only Memory), RAM is a volatile memory, meaning its contents are lost when the computer is powered off or restarted. The motherboard is the main circuit board of a computer that connects all the components together, including the RAM. Therefore, the correct answer is RAM.

    compact disc
    Explanation
    The full form of CD is "compact disc". A compact disc is a small, portable storage medium used for storing and playing back audio, video, and other digital data. It was introduced in the 1980s and quickly became popular due to its high storage capacity and superior audio quality compared to traditional analog formats. Compact discs are read by lasers, which scan the disc's surface to retrieve the stored information. They are commonly used for music albums, software installations, and data backup purposes.

    Correct Answer
    A. Napier Bones

Napier Bones, also known as Napier's rods, are a set of numbered rods or bones that can be arranged and manipulated to perform multiplication and division calculations. This mechanical device was invented by John Napier in the 17th century and was widely used before the invention of modern calculators. Therefore, Napier Bones is the most appropriate option for a machine used for multiplication.
