What is the Difference between Big Data and IoT?

Big Data is a collection of data from places like Articles, Social Media posts, Sensor Data and Device data, etc., which is accessible by the organization for Analysis and used for Predictions. IoT is one source of Big Data which collects data through Sensors and stores it in a Database.

IoT can do much more functions than Big Data. How? It collects data analyzing it in real time events and make sure to integrate any insight of rest of your Business.
For Example, Consider a Smart car is having multiple sensors like Engine Temperature, Brakes, Fuel Sensor and More. Using IoT you can detect the problems and correct them by sending a notification about Engine Temperature or Brake Failures. Even it can notify the nearest Service Station. Ok, that’s all about IoT but what is the use of Big Data. Using Big Data the data collected from all the vehicles are analyzed. If a problem occurs in a car, we can find out which Manufacturing Unit caused the problem and also the root cause of the problem.
In simple words, Big data is all about Data and IoT is about Data, Devices and Connectivity.
