Read-only memory (ROM) and Random Access Memory (RAM) are two fundamental types of memory in computing systems, each serving a distinct purpose. ROM is a non-volatile memory, which means it retains its data even when the power is turned off. It is used to store firmware, which is the software that boots up the system. RAM, on the other hand, is a volatile memory, losing its data when the power is switched off. It’s used for storing the data and programs that a computer is currently using, allowing for quick access and manipulation. While ROM is read-only, as the name suggests, and contains unchangeable data, RAM allows both reading and writing operations and contains data that is constantly being changed and updated as the system operates. This makes RAM much faster, but it also means that it requires a constant power supply to maintain its data, unlike ROM.
