ROM (Read-Only Memory) stores data permanently, meaning the data cannot be easily altered or erased. It's typically used to store the computer's boot instructions (BIOS) and firmware – essential instructions needed to start the computer. Data is read from ROM, but not easily written to.
RAM (Random-Access Memory) is volatile memory, meaning data is stored temporarily and is lost when the power is turned off. It's used for actively running programs and data that the computer is currently using. RAM allows for fast reading and writing of data, enabling quick access to information.
Here's a summary:
- ROM: Permanent storage, read-only, used for boot instructions and firmware.
- RAM: Temporary storage, volatile, used for running programs and active data.
