The CAI programs can be prepared in a variety of modes like tutorial, problem solving modeling etc. For multimedia computers CD’s are also available for educational /training purposes on almost every subject with audio/video features known as CBT (Computer Based Training).
Computer Aided Designing
Computer Aided Design (CAD) and computer aided manufacturing (CAM) are one of the most powerful application applications Engineers, scientist and designers use CAD software to design a machine, car, building etc. These designs can be viewed in 3D before the production of machines. Computers can also control manufacturing machines like drill, lathe machines. An integrated CAD/CAM system help to produce quality machines, where a software takes designing information from CASD database and convert them into other program which controls and activate the manufacturing machines.
Computers in Medical
Computer aided diagnostic machines are used to diagnose various types of disease. It also helps in surgery and treatment. Eye testing, scanning of internal parts of brain, by pass surgery, pathological tests are the examples where computers are used effectively.
Animation & Graphics
