Differnce between RAM and ROM

Answer Posted / ravi

There is one major difference between a ROM and a RAM chip. A ROM chip is non-volatile storage and does not require a constant source of power to retain information stored on it. When power is lost or turned off, a ROM chip will keep the information stored on it. In contrast, a RAM chip is volatile and requires a constant source of power to retain information. When power is lost or turned off, a RAM chip will lose the information stored on it.
Other differences between a ROM and a RAM chip include:
A ROM chip is used primarily in the start up process of a computer, whereas a RAM chip is used in the normal operations of a computer after starting up and loading the operating system.
Writing data to a ROM chip is a slow process, whereas writing data to a RAM chip is a faster process
A RAM chip can store multiple gigabytes (GB) of data, up to 16 GB or more per chip; A ROM chip typically stores only several megabytes (MB) of data, up to 4 MB or more per chip
