Theory:

In the previous section, we have learned the basics of files and folders. In this section, we will see "How can we create Files?".
 
For example, if the computer operates on the Windows OS, we can collect our notes in the 'Notepad' application and draw pictures in the 'Paint' application.

We can type our notes in 'Notepad' and save the created files in a folder as per their name.
 
Likewise, we can draw and edit pictures in the' Paint' app. Let us see how to use these images to create image galleries, animations, and graphics.
 
Pictures and audio-visuals give us more understanding than teaching and writing on the blackboard. Is it right?

Instead of saying a story like 'once upon a time, there was a king,' we can understand the concept easily by seeing the video, and also it registers firmly in the minds of the students. The device that helps explain the concepts easily through pictures is called the 'Visual Communication Device'.
 
For example, photos, audio-visuals, drawings, animations all can be created easily with the help of the computer. Cinema is an excellent example of a 'Visual Communication' device.
