DRAM	DRAM (Dynamic Random Access Memory)- Is one type of RAM but it is refreshed over 1000 per second. This makes it slower than SRAM, but it is more common and less expensive.
SRAM	SRAM (Static Random Access Memory)- Is the other type of RAM it is not refreshed and has access times of up to 10 nanoseconds. However it is so much more expensive than DRAM, even though it is up to 6 times faster.
