Which type of memory is only preserved while the system is powered up?

Volatile memory is the type of memory that requires power to maintain the stored information. When the power is turned off, all data in volatile memory is lost. This is crucial for system performance, as volatile memory like RAM (Random Access Memory) provides fast read and write capabilities, which are essential for the temporary storage of data that a computer is actively using.

In contrast, static memory refers specifically to a type of volatile memory that retains data as long as power is supplied, but it is typically used in applications like cache memory due to its speed. Non-volatile memory, such as flash memory or hard drives, retains data even when the power is off, making it suitable for long-term storage. Read-only memory (ROM) is also non-volatile and is used for storing firmware. Understanding these differences highlights why volatile memory is recognized for its temporary data preservation only while a system remains powered on.
