Differences between Read-Only Memory (ROM) and Random Access Memory (RAM)
ROM (Read-Only Memory) is a form of permanent storage. It contains instructions or data that are permanently written during manufacturing and cannot be altered or modified afterward. Even without electricity, the data stored in ROM remains intact. It doesn’t require power to retain information. ROM holds critical instructions needed for booting up the computer, such as the initial firmware. It also stores software instructions for devices like printers. Users cannot change the data stored in ROM.
RAM (Random Access Memory) is volatile memory, meaning it temporarily stores data while your computer is running. When you shut down or restart your computer, the data in RAM is erased. RAM relies on an electric current to hold data. When there’s no power, the data disappears .RAM stores files and data that your computer is currently using. Each time you switch between programs or pages, the information is instantly available from RAM. Volatile memory can be easily changed, upgraded, or expanded by users. ROM provides permanent instructions for your computer, while RAM serves as temporary working memory for active tasks. ROM is non-volatile, and RAM is volatile, making them essential components with distinct roles in a computer system.
