Differentiate between RAM and ROM?

Semiconductor memories are of two types: RAM (random access memory) and ROM (read only memory).RAM is a read/write memory. Information can be written into and read from a RAM. It is volatile memory.It stores information so long as power supply is on. ROM is permanent type memory. Its contents are not lost when power supply goes off. the user cannot write into a ROM.Its contents are decided by the manufacturer and written at the time of manufacture.Programmable ROMs are also available. They are called PROMs.
