what is the difference between ram and rom
RAM = random access memory ROM = read only memory Answer originally posted in response to What is the difference between ram and rom?
RAM is a part of computer hardware which stores the operating system application programs and data or currently running processes kept so that they can quickly reach to the computer’s process. ROM is a CD-Rom storage, Floppy Disk every computer has a small capacity of ROM that holds enough programming which can load the operating system to the RAM.
ROM: Read only Memory(transistor based) RAM: Random Access Memory(capacitive based) ROM: Non-Volatile, means that it doesn’t need to be refreshed with power to keep the data stored. You can read data as much as you want but only write once. Other versions of ROM such as EPROM and EEPROM can erase the data and therefore enable you to re-write to the memory. RAM:Volatile, means that the memory needs to be refreshed and if not (power is turned off) then the data is lost. You can read and write as much as you want.
