Big data refers to a large quantity of data that has to be processed at one time. With the advancement of social media and the virtual world, a vast amount of data is created every second. A technique has to be designed to effectively process this ever-increasing collection of information. One such algorithm is the MapReduce algorithm. The result or output of the algorithm provides useful insights about the data used as input and can be further used for decision making and prediction algorithms. Also, new data is generated frequently for big data processing.
