RAM (Random Access Memory) is a kind of memory used in computers to temporarily store data and instructions. It allows data and instructions to be read and written randomly, and the stored contents will be lost when the power is turned off. Therefore, RAM is mainly used to store programs and data used during short-term operation.

ROM (Read-Only Memory) is a kind of memory that can only read pre-stored data but cannot write data. The data in ROM is usually written once during the manufacturing process and saved permanently, so it does not lose data after a power outage. ROM is often used to store fixed programs and data, such as operating system boot programs, important parameter settings, etc.

In general, the main difference between RAM and ROM is the readability and storage method of data. RAM is readable and writable, and the stored content can be changed at any time, while the data in ROM can only be read and cannot be modified.
