            RAM is describe as a acronym for Random Access Memory meaning memory type where a byte that can be randomly accessed without touching previous bytes or amount of memory. RAM is volatile meaning they lose their content while they are powered down. There are 2 types of ram DRAM and SRAM which mean Dynamic RAM and Static RAM respectively. SRAM is faster than DRAM since it can be accessed within 10 nanoseconds while DRAM can be accessed through 60 nanoseconds.

Random Access Memory (RAM) is a type of storage. This allows stored data to be accessed in any order at randomness. In this state, random means returning data in a constant time regardless of its location or its order with previous pieces of data. The word RAM is often associated with volatile types of memory where information is lost after the power is switched off.

RAM is explained as Random Access Memory that provides space for the computer to write and read data to be accessed by the CPU. The more RAM that is put into the computer the less number of times the CPU has to read data from the hard disk. The differences from SDR, DDR, DDR2, and DDR3 is that SDR is single data rated ram, DDR is doubling the rate, DDR2 is doubling the channel or cache from which data is being processed through, and it is the same increase for DDR3.
