    A To increase the size of the physical memory Correct Answer Incorrect Answer
    B To provide faster access to data in RAM Correct Answer Incorrect Answer
    C To allow multiple programs to run concurrently Correct Answer Incorrect Answer
    D To extend the available memory by using secondary storage as a supplement Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    Virtual memory allows an operating system to use a combination of RAM and secondary storage (usually a hard disk) to provide the illusion of a larger main memory. When the physical RAM is full, the OS can swap data between RAM and disk, thus extending the usable memory space.
