1.RAM(Random Access Memory)
this memory consists of some integrated circuit(IC) chips either on motherboard or on a small circuit board attached to motherboard. A computer's motherboard usually has flexibility to easily add more memory chis for enhancing the memory capacity of the system. Hence, if a user decides to have more memory than his/her computer currently has, he/she can bye more memory chips and plug them in empty memory slots on the motherboard. Normally, service engineers do this job.
RAM is of two types:-
1. Dynamic RAM :- In this use an external circuitry to periodically "regenerate" or refresh storgage charge to retain the store data.
2. Static RAM :- does not need any special regenrator circuit to retain the storage data. It takes more transistors and other devices to store a bit in a static RAM.
