Ram

[Amrit]

Many personal computers are designed to add the additional type of RAM modules up to a certain limit.
RAM is very small, both in physical size (it's stored in microchips) and it can hold the amount of data as well as it is also a much smaller than the hard disk. A computer may come with 256 million bytes of RAM (Random Access Memory) and a hard disk that can hold approximately 40 billion bytes. Generally the RAM (Random Access Memory) comes in the form of "discrete" (meaning separate) microchips as well as in the form of modules that can plug into the holes in the computer's motherboard.

Dear Amrit ,I think you have not sufficient knowledge about Ram.Ram stores data only in temporarily fashion. It sends the instructions ( which we give to the computer) to microprocessor. Microprocessor execute the instructions and send back to the Ram.
Latest branded computer comes with minimum ram 512 mb. There is two ram slots on motherboard through which we can increase our Ram.in assembled computer it depends upon the customer that how much Ram he wants to install in his computer.
