What is volatile and nonvolatile memory ?|| about volatile memory ||

Volatile storage and nonvolatile storage refer to two different types of computer memory that differ in terms of their persistence of data.

Volatile storage, as the name suggests, is a type of memory that is volatile or temporary in nature. This means that any data stored in volatile memory will be lost when the power is turned off or when the system is restarted. The most common example of volatile storage is RAM (Random Access Memory) which is used to temporarily store data that the CPU needs to access quickly.

Nonvolatile storage, on the other hand, is a type of memory that retains its data even when power is turned off or the system is restarted. The most common examples of nonvolatile storage are hard disk drives (HDDs) and solid-state drives (SSDs), which are used to store the operating system, applications, and user data. Nonvolatile memory can be read and written multiple times and can retain its data for years or even decades.

In summary, volatile storage is temporary memory that loses data when the power is turned off, while nonvolatile storage retains data even when power is turned off.
