Types of Computer Memories

We have come a long way from the days when heavy tape drives were used to store information to hand held little devices available today. Computer memory is nothing but the collection of data on physical devices in a digital format i:e 0's and 1's.

To classify memory, there are two types broadly, one is volatile and the other is non volatile. As their name suggests, volatile memory can store information only till it is supplied with electric energy and non volatile memory can retain the information even after the supply is disconnected.

In present day computers, RAM is a volatile but high speed memory, while Hard Drives are non volatile but low speed memory. There are many types of volatile and non volatile memories that have been developed. Among them, Different types of RAM like SDRAM, DDR, DDR2, DDR3 etc stand for volatile and flash drives, hard disks and optical storage devices are a few types that come under the non volatile category.
