Computers make all modern communication possible.
They operate telephone switching systems, coordinate satellite launches and operations, help generate special effects for movies, and control the equipment in all phases of television and radio broadcasts.
Local-area networks (LANs) link the computers in separate departments of businesses or universities, and larger networks, such as the Internet, permit modems telecommunication devices that transmit data through telephone lines to link individual computers to other computers anywhere in the world.
Journalists and writers now use word processors to write books and articles, which they then submit to publishers on magnetic disks or through telephone lines.
The data may then be sent directly to computer-controlled typesetters, some of which actually design the layout of printed pages on computer screens.

Computers are used by scientists and researchers in many ways to collect, store, manipulate, and analyze data.
Running simulations is one of the most important applications.
Data representing a real-life system is entered into the computer, and the computer manipulates the data in order to show how the natural system is likely to behave under a variety of conditions.
In this way scientists can test new theories and designs or can examine a problem that does not lend itself to direct experimentation.
Computer-aided design, or CAD, programs enable engineers and architects to design three-dimensional models on a computer screen.
Chemists may use computer simulation to design and test molecular models of new drugs.
Some simulation programs can generate models of weather conditions to help meteorologists make predictions.
Flight simulators are valuable training tools for pilots.

Computers have opened a new era in manufacturing and consumer-product development.
In the factory, computer-assisted manufacturing, or CAM, programs help people plan complex production schedules, keep track of inventories and accounts, run automated assembly lines, and control robots.
Dedicated computers are routinely used in thousands of products ranging from calculators to airplanes.

Government agencies are the largest users of mainframes and supercomputers.
They use computers for hundreds of tasks, including research, breaking codes and interpreting data from satellites.
The Inland Revenue uses computers to keep track of tens of millions of tax returns.
Computers are also essential for taking the census, maintaining criminal records, and other tasks.

Computers have proved to be valuable educational tools.
Computer-assisted instruction, or CAI, uses computerized lessons that range from simple drills and practice sessions to complex interactive tutorials.
These programs have become essential teaching tools in medical schools and military training centers, where the topics are complex and the cost of human teachers is extremely high.
Educational aids, such as some encyclopedias and other major reference works, are available to personal-computer users either on magnetic disks or optical discs or through various telecommunication networks.

Video games are one of the most popular applications of personal computers.
The constantly improving graphics and sound capabilities of personal computers have made them popular tools for artists and musicians.
Personal computers can display millions of colors, can produce images far clearer than those of a television set, and can connect to various musical instruments and synthesizers.
Painting and drawing programs enable artists to create realistic images and animated displays much more easily than they could with more traditional tools.
"Morphing" programs allow photographers and filmmakers to transform photographic images into any size and shape they can imagine.
High-speed supercomputers can insert life-like animated images into frames of a film so seamlessly that movie-goers cannot distinguish real actors from computer-generated images.
Musicians can use computers to create multiple-voice compositions and to play back music with hundreds of variations.
Speech processors even give a computer the ability to talk and sing.
