ROM is Read Only Memory. Normally, data is fabricated into the ROM chips by the semiconductor manufacturer. Special mask(s) have to be made to store this data.
Besides ROM chips there are PROM chips, where P stands for Programmable. In these chips, data can be stored by the end user. EPROM is Erasable PROM. A new type of ROM is OTP ROM (One Time Programmable).

Once the system is off, all the data stored in RAM(volatile memory) will be lost. So, ROM is used to store the data for a desired period of time.
