Detailed explanation-1: -Primary storage is often referred to as “memory” and is classified as either volatile or non-volatile. Volatile memory such as RAM loses data as soon as the device loses power. The flash memory in solid-state drives (SSDs) is non-volatile because the data remains in storage even after you have turned it off.
Detailed explanation-2: -Non-volatile memory is typically used for the task of secondary storage or long-term persistent storage. The most widely used form of primary storage today is a volatile form of random access memory (RAM), meaning that when the computer is shut down, anything contained in RAM is lost.
Detailed explanation-3: -Volatile storage devices lose data when power is interrupted or turned off. By contrast, non-volatile devices are able to retain data regardless of the status of the power source. Common types of volatile storage include static random access memory (SRAM) and dynamic random access memory (DRAM).
