ROM, is Read Only Memory. It is a secure chip on which the manufacturers have burned data the computer needs in order to boot up the Operating System. It is not affected on losing power. RAM, on the other-hand, is Random Access Memory, and is very volatile, losing any data held in memory on powering down.

What differenc between ROM and RAm?
ROM isn't erased when you turn the power off, whereas RAM is.
What is the permanent memory chip inside your computer called?

What is the memory that holds items that can be read but not erased or changed?

How can be erase data stored in ROM?
A standard ROM or PROM cannot be erased, only erasable PROM can be erased. It is done with either UV light or electronically depending on the type of EPROM.
What is memory that cannot be changed or erased?
Read Only Memory or ROM. There are also Erasable ROMs called EPROMs, EAROMS, EEROMS, and Flash Memory. The erasable ROMS will only be erased under special circumstances, and when in use they act the same as a normal ROM.
Why rom is non volatile memory?
ROM is involatile because its name means Read Only Memory, hinting that the data stored on it cannot be altered. The word involatile means long term and not changeable.
Which type of ROM can be erased by UV light?
The type of ROM that can be erased by UV light is called a PROM (Programmable Read-Only Memory). PROM chips have fuse links that can be erased using UV light, allowing the chips to be reprogrammed.
What is correct CD-rom?

Which type of rom can erased and re-written without having to remove the chip from the computer?
An EEPROM chip
What is the classification of ROMs?
Rom :- Read Only Memory. The storage of data and instructions in Rom is permanent. It does not depend on the power supply. The memory which does not lose its content when power is turned off is known as non-volatile memory. There are three types of Rom :- Prom = Programmable read only memory Eprom= Erasable Prom EEprom=Electrically erasable prom
