What is the difference between RAM and ROM?

The distinction between RAM (Random Access Memory) and ROM (Read-Only Memory) primarily revolves around their volatility and usage in computing devices. RAM is classified as volatile memory, meaning that it loses its stored data when the power is turned off. This characteristic makes it suitable for temporary data storage, such as running applications and active processes. In contrast, ROM is non-volatile memory, which means it retains its data even when the power is turned off. ROM is typically used to store firmware or software that is not meant to be modified frequently, such as the system's boot process or basic input/output system (BIOS).

Understanding this difference is crucial for comprehending how computers manage memory and data storage effectively. The other choices do not accurately describe the fundamental properties of RAM and ROM. For instance, while it's true that ROM typically has a slower access speed than RAM, stating that ROM is faster is incorrect. Moreover, RAM can be both read from and written to, while ROM is primarily designed for reading data, thus making the assertion that RAM is read-only not accurate.
