Volatile and non-volatile memory are two types of computer memory that differ in terms of their ability to retain data when power is removed from the system.
Volatile memory refers to a type of memory that requires a continuous power supply to retain the stored data. This means that when the power is turned off or interrupted, the data stored in volatile memory is lost. The most common example of volatile memory is Random Access Memory (RAM). RAM is used by the computer's operating system and applications to temporarily store data that is actively being used. It provides fast access to data, allowing for quick retrieval and modification. However, since RAM is volatile, it cannot retain data once the power is removed or the system is shut down.
On the other hand, non-volatile memory is a type of memory that can retain data even when the power supply is disconnected. This means that the data stored in non-volatile memory remains intact even after power loss or system shutdown. Non-volatile memory is commonly used for long-term storage of data that needs to be preserved, such as the computer's firmware, operating system, and user data. Examples of non-volatile memory include Read-Only Memory (ROM), Flash memory, and hard disk drives (HDDs). These storage devices can retain data even when the power is turned off, making them suitable for storing important system files and user data.
In summary, the main difference between volatile and non-volatile memory lies in their ability to retain data without a continuous power supply. Volatile memory loses data when power is removed, while non-volatile memory can retain data even when power is disconnected.
