                 What is a Bug?

                 A bug is an unexpected problem in your program. You follow a defined sequence to write a program,
                 from which you expect to return a specific output. Any change in the expected and actual output of
                 the program is said to be the result of a bug.
                 So, we can say that bug is a general term which is used to describe any unexpected problem with
                 hardware or software.

                 Example: Suppose you are going out for a family picnic. You are ready to go, but you notice that the
                 tyre of the car is puncture, due to which your picnic will get delayed for few hours or you need to
                 postpone it for some other day. As first you need to repair the tyre. So, this puncture in the tyre of
                 the car can be termed as a ‘bug’ in programming.

                 What is an Event?

                 Event is an action which has happened. You can consider event as a generalization of things on
                 which the program responds.
                 In programming, an event is an action which occurs as a result of the user or another source, such
                 as a mouse click.

                 Examples of the events are:
                   Clicking and loading the web page on web browser

                   Creation of file in a file system
                   Webcam or microphone receiving sensory input

                   Incoming network traffic
                   Typing on keyboard

                   Timer
