Data Definition

Data is raw or unorganized facts data needs to be processed in order to make it understandable for the user. It is not useful for the end user until it is processed and organized into something useful.

For example we stored 80 in a php variable $mos : $mos= 80; . But actually, we have stored the marks of the student (mos) which is 80. For the end-user it is not useful at all, as it would be hard know what does it exactly means. But if the same data is processed and show to the user it becomes useful for the user hence called as information. Example, echo “Marks of the Student : “; ech0 $mos;

Result : Marks of the Student : 80.
