USES OF COMPUTER

People use computers in many ways; business, computers are used to track inventories with bar codes and scanners, check the credit status of customers, and transfer funds electronically, homes, tiny computers embedded in the electronic circuitry of most appliances control the indoor temperature, operate home security systems, tell the time, and turn video cassette recorders (VCRs) on and off, automobiles regulate the flow of fuel, thereby increasing gas mileage, they also entertain, creating digitized sound on stereo systems or computer-animated features from a digitally encoded laser disc.  

Computer programs, or applications, exist to aid every level of education, from programs that teach simple addition or sentence construction to programs that teach advanced calculus. Educators use computers to track grades and communicate with students; with computer-controlled projection units, they can add graphics, sound, and animation to their communications. Computers are used extensively in scientific research to solve mathematical problems, investigate complicated data, or model systems that are too costly or impractical to build, such as testing the air flow around the next generation of aircraft. The military employs computers in sophisticated communications to encode and unscramble messages, and to keep track of personnel and supplies.
