Big Data is a lot of data collected and stored from individual people through many ways such as social media activity and buying activity online. The masses of data is processed and analysed by computational methods. It is so much data that it pushes the boundaries of current technology to process because of its size. The information can be used in order to target certain people with information such as advertising. An example of big data is Facebook likes. Facebook stores all of your activity and can paint a picture of who you are based on your likes in order to target specific adverts to you. Big data can also be used to manipulate the outcome of political campaigns by showing targeted people certain adverts to try to sway their opinion.
