What is the difference between RAM and ROM?

• A. RAM is used for permanent storage, while ROM is for temporary
• B. RAM is volatile memory, while ROM is non-volatile
• C. RAM is faster than ROM in all cases
• D. RAM can only store graphics data, while ROM stores text data

Answer: (B)

The correct answer highlights a fundamental distinction between RAM and ROM based on their volatility. RAM, or Random Access Memory, is characterized as volatile memory, meaning that it loses all stored data when the power is turned off. This type of memory is used by the computer to store data that is actively being used or processed, allowing for quick access and modification as required by running applications. On the other hand, ROM, which stands for Read-Only Memory, is classified as non-volatile memory. This means that the data stored in ROM remains intact even when the power is turned off. ROM is typically used to store firmware or software that is intended to operate without frequent changes, such as the computer's BIOS or system firmware. Therefore, this distinction between the two types of memory defines their use cases and essential characteristics, making option B the correct choice. The other options mischaracterize the roles and functionalities of RAM and ROM, leading to misconceptions about how these types of memory operate within a computer system.
