The correct answer is RAM.
- RAM is a volatile memory while ROM is a non-volatile memory.
- While RAM allows the computer to read data to run applications, ROM stores all the application which is required to start the computer initially.
- RAM can perform both read and write operations on the information stored in it.
- ROM allows the user to read the information but not write the information. It is used to store permanent information, which is non-erasable.
- MROM, PROM, EPROM, and EEPROM are different types of ROMs.
