1.      RAM & ROM

RAM (Random Access Memory) has the capability of storing new information in a specific memory location by a write operation. Information retained in RAM can be transferred to some other device by a read/write operation, that is why, it is sometimes also referred to as a read/write memory. However RAM is volatile and its contents get lost on power supply failure. RAM enables quick read or write operation because the required memory location can be selected easily and quickly via, its unique address. ROM memory has also got random access capability.

ROM (Read Only Memory) does not have both read and write facilities; it can only be read. ROM is used for holding the programs which must be permanently held in memory so that the set of instructions is immediately available for execution when power is supplied to the equipment. In ROM, the memory device is pre-programmed during the manufacturing stage, leaving the information permanently stored for later retrieval.
