Memory Unit II - SS2 ICT Past Questions and Answers - page 3

Primary memory is essential for providing fast access to data and instructions required for real-time processing by the CPU. It enables the efficient execution of programs and tasks, making the computer responsive to user interactions. Secondary memory, on the other hand, plays a critical role in storing data and programs for the long term. It allows users to store files, applications, and the operating system even when the computer is turned off. Without secondary memory, data would be lost every time the computer is powered down, and users would need to reinstall software and reload data each time they use the computer.
