Computers are sometimes thought unjustifiably to demand deep technical knowledge or proficiency in mathematics and electronics. In the actual sense of the term, computers, like any other discipline, inspire different levels of expertise. On the least specialized level, computer literacy involves knowing how to turn on a computer, start and stop simple application programmes, and save and print information. People use computers in a wide variety of ways. In 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 on or off.
Computers in automobiles regulate the flow of fuel, thereby increasing gas mileage. Computers also entertain, creating digitized sound on stereo systems or computer-animated features from a digitally encoded laser disc. Computer programmes or applications exist to aid every level of education from programmes that teach simple addition or sentence construction to advanced calculus. Educators use computers to track grades and prepare notes. With computer controlled projection units, they can add graphics, sound and animation to their lectures.
