Data, Information and Knowledge


People often use the terms data and information interchangeably but there is a distinction
when we use them with reference to computers.
Data is a collection of facts, or an idea. Data can be a number, a word, a picture, or even a
recording of sound. For example 04933239230 is a number and the names Saji and Khan are
pieces of data. But they are of no use to anyone. When we are presented with a contact list that
shows Saji Khan and his phone number as 04933239230, then it is useful. This is information.
