There are many applications in the computer which people usually see because the computer is the combination of hardware and software. Application is the software. I’m sure all of us have been known about word processor because this kind of application is the most popular application in the world which people often use for many things. The most important objects of interest in a word processor are the word themselves. Indeed, the visibility of text on a continual basis was one of the major usability advances in moving from line-oriented to display-oriented editors. Depending on the user’s application, there may be other objects of interest in word processing that may or may not be visible. For example, are the margins for the text of screen similar to the ones which would eventually printed? Is the spacing within a line and the line breaks similar? Are the different fonts and formatting characteristics of the text visible without altering the space? Expressed in this way, we can see the visibility criterion for direct manipulation as very similar to the criteria for what you see is what you get. You can see this one inside the digital computer ability which is improved day by day with the newest technology.
