    Question

    Which type of memory requires frequent refreshing to retain

    data?
    A SRAM (Static RAM) Correct Answer Incorrect Answer
    B DRAM (Dynamic RAM) Correct Answer Incorrect Answer
    C EPROM (Erasable Programmable Read-Only Memory) Correct Answer Incorrect Answer
    D EEPROM (Electrically Erasable Programmable Read-Only Memory) Correct Answer Incorrect Answer
    E PROM (Programmable Read-Only Memory) Correct Answer Incorrect Answer

    Solution

    DRAM (Dynamic RAM) stores data using capacitors that gradually lose charge, requiring constant refreshing to maintain the stored information. It is widely used in personal computers, workstations, and servers due to its cost-effectiveness and high storage density.

    In contrast, SRAM (Static RAM) does not require refreshing and is faster but more expensive.
