Whatever we can read, write, speak, and observe is data. Every day we share so much data when we read, write, speak, and watch. It can be numbers, alphabets, symbols, or a combination of all of these. Examples – 100 (number – integer), 11.2 (number – decimal), A (alphabet), Apple (word – a set of alphabets), 18/12/2020 (date – a combination of numbers and symbols).
Nearly every action that we take in our daily lives generates data. Be it in the physical world or the digital world. Sensors, machines, mobile apps, websites are all around us, and every interaction we do with them generates a massive amount of data.
Data can be defined as facts or information which when stored, can be used as a basis for decision making, calculation, or discussion.
