Big data is a term that describes the large volume of data. It can be used in all kinds of ways. For example, the government uses it to know about how many people travel on buses or trains. The information is then used to make bus or train systems better. Companies use big data, too. It helps them to know about who buys their products.
Big data can be used for good reasons. Some hospitals use big data to predict if a baby who is born too early will get sick. The hospital can then take extra steps to take care of that baby so he or she does not get sick. Big data can also be used for bad reasons. Some bad people may try to steal others’ information and sell it for money.
How can big data be used for good and bad things? It is because the computer programmes used to look at big data and understand it are written by people. Because people think in a certain way, they build a model of those ideas. These ideas are then used to look at the data. Sometimes, these ideas are helpful for people or businesses. Other times, bad ideas can cause problems for certain groups of people.
