Characteristics of Primary Storage - JSS2 Computer Studies Lesson Note

Volatility: Primary storage is volatile, meaning it loses its stored information when the power is turned off. This characteristic makes it unsuitable for long-term storage but ideal for tasks requiring fast access and retrieval of data during active computing.

Speed: Primary storage systems, especially RAM and cache memory, offer high-speed access to data. This speed is crucial for ensuring the efficient execution of programs and tasks by the CPU.

Direct Accessibility: Data in primary storage can be directly accessed by the CPU. This direct accessibility allows for quick retrieval and manipulation of information, contributing to the overall performance of the computer system.
