    Which of the following is a temporal storage?

    • Register

    • ROM

    • RAM

    • CMOS

    Correct Answer
    A. RAM
    Explanation
    RAM stands for Random Access Memory, and it is a type of temporary storage in a computer system. It is used to store data that is actively being used by the computer's processor. Unlike ROM (Read-Only Memory) which stores permanent data that cannot be modified, RAM allows for read and write operations, making it a suitable choice for temporary storage. Registers, on the other hand, are small, high-speed storage locations within the processor itself, used for holding frequently accessed data. CMOS (Complementary Metal-Oxide-Semiconductor) is a type of technology used in manufacturing computer chips and is not a form of storage.
