Explain What is DRAM? In which form does it store data?


DRAM is the Hershey's chocolate of readable/writable memory:
it's not the best, but it's cheap, does the job, and is
available almost everywhere you look. DRAM data resides in a
cell made of a capacitor and a transistor. The capacitor
tends to lose data unless it's recharged every couple of
milliseconds, and this recharging tends to slow down the
performance of DRAM compared to speedier RAM types.
