RAM

What is RAM? Describe different types of RAM.

RAM stands for Random Access Memory. It is also called direct access memory. It is used to store data and instructions temporarily. RAM is a volatile memory. It means that its contents are lost when the power is turned off. There are two types of RAM.

i. DRAM. DRAM stands for Dynamic RAM. It requires an electric current to maintain its electrical state. DRAM is recharged again and again to maintain its data.

ii. SRAM. SRAM stands for Static RAM. It does not need to recharge again and again to maintain its data. It is faster than DRAM.
