🧠 Explanation:
Primary storage is faster and directly accessible by the computer’s processor compared to secondary storage. It temporarily holds data and instructions needed for immediate processing, which helps improve the overall speed and efficiency of the system. Although its capacity is smaller, primary storage plays a crucial role in the smooth functioning of a computer. Unlike secondary storage, data in primary storage is usually lost when the power is turned off.
