Computers are helpful because they offer a wide range of functions and services that are not available anywhere else. There are four main uses: word processing, internet/communications, digital video/audio composition, and desktop publishing. Although one can create a typed paper with a typewriter, the computer has more features to do it with. Internet and communications, digital video and audio composition, and desktop publishing are all features that are only offered on computers. With these tools human society has progressed exponentially.

The word processing capabilities of computers are amazing. They can automatically correct your spelling and grammar mistakes. The cutting and pasting features are incredibly simple and very useful for revision. Plus it is easier to read a word-processed document than one written by hand. Having a digital backup is an added benefit. All of these things help writers get the job done. If we want to add pictures to your writing, numerous software titles are available for desktop publishing. With desktop publishing, we can create page layouts for entire books on our home computer. For example, high school yearbook classes now use desktop publishing software for the creation and design of their yearbooks. Most of this cannot be done by hand, and if so, then it is painstakingly laborious.

Computers have been used to coordinate information between multiple locations since the 1950s. The U.S. military's SAGE system was the first large-scale example of such a system, which led to a number of special-purpose commercial systems such as Sabre. In the 1970s, computer engineers at research institutions throughout the United States began to link their computers together using telecommunications technology.
