What is the difference between RAM and ROM?

The distinction between RAM and ROM is essential in understanding computer memory and its functions. RAM, or Random Access Memory, is classified as volatile memory, meaning that it temporarily holds data that is actively in use while the computer is powered on. When the power is turned off, all data stored in RAM is lost. This type of memory is designed for high-speed data access, allowing for quick read and write operations which is crucial for running applications and processing tasks efficiently.

On the other hand, ROM, or Read-Only Memory, is non-volatile, which means it retains its data even when the power is switched off. ROM is used to store firmware and system software that is not intended to be modified frequently, such as the BIOS in computers. As a result, the data contained in ROM is permanent and remains unchanged under normal operations.

Thus, stating that RAM is volatile memory used for temporary data while ROM is non-volatile memory used for permanent data accurately captures the key characteristics that define each type of memory, making it the correct choice.
