When you are using a computer, you are constantly provoking events that will lead to actions being performed by the computer. For example, when you are moving the computer mouse, the sensory input on the bottom of the device is telling the cursor on the screen to move. Likewise, if you were to click an icon on the screen, the clicking event is initiated as a result of that action.
This sort of programming is very common in computer operating systems and graphical user interfaces. This means you are likely to come across event driven programming when you are playing a computer game or navigating your computer’s user interface. It makes use of input devices such as a mouse or a joystick, as well as giving users the ability to move around and interact with a system with relative ease.
In the past, computers could only be operated solely by entering the precise code required to initiate an action. This meant that a considerable amount of training was needed if you were to operate a computer correctly. However, thanks to the technological developments over time, event driven programming has made computers far easier to operate.
Event driven programming is greatly beneficial because of how user friendly it makes computer applications. It means that almost everyone can operate these systems without the need for expert knowledge on computer programming code such as SQL and Visual Basic.
