Question

Explain the different types of memory in hierarchy

Answer 1

1. Memory Hierarchy

Memory is categorized into volatile and nonvolatile memories, with the former requiring constant power ON of the system to maintain data storage.

Furthermore, a typical computer system provides a hierarchy of different times of memories for data storage.

2. Data movement

In order to perform computation, data must travel from the secondary storage to the CPU. Due to the vast differences in access speed and storage capacity, the operating system performs a series of sophisticated steps (both at the levels of hardware and the software).
