RAM stands for Random Access Memory. RAM is the part of a computer that holds the programs that are currently running. It consists of a chip on a circuit board in a computer, and it stores information that can be accessed randomly. This allows storage and retrieval whenever needed making it ideal for the in-process programs and services running. Most RAM is volatile, so it won´t hold information when the computer is turned off. There are several types of RAM in different configurations. SDRAM is the most common, with variations called DDR, DDR2, and DDR3 which stands for Dual Data Rate.
