    RAM stands for

    • Random Access Memory

    • Really Annoying Machine

    • Read A Manual

    • Real Absolute Memory

    Correct Answer
    A. Random Access Memory
    Explanation
    RAM stands for Random Access Memory. It is a type of computer memory that allows data to be stored and retrieved by the computer's processor quickly. Unlike other types of memory, RAM is volatile, meaning that its contents are lost when the computer is powered off or restarted. RAM is an essential component of a computer system as it provides temporary storage for data that is actively being used by the processor. This allows for faster access and processing of data compared to other types of storage, such as hard drives or solid-state drives.
