This is an important question and one that is getting increasingly important with the passage of time. There are several reasons this fact. First, you need to realize that every year that goes by there is more and more information in all fields and there is a strong argument to be made that the greatest work is being done in the sciences. And when we consider that this information is coming from all around the world, we need a way to get easy access. Information technology allows for the spread of information as well as the use of this information.
Second, we need to realize that the way this information is categorized is important as well. There are so many different ways to categorize things. Therefore, the study of information technology seeks to categorize bodies of information in ways that are most helpful. These two reasons alone show the importance of information technology. Accessibility and easy of use are absolutely important and will continue to be so in the future.
