.  Some of the application areas of the computer are listed bellow: 1. Education: Computers are extensively used, as a tool and as an aid, for imparting education. Educators use computers to prepare notes and presentations of their lectures. The computer provides a tool in the education system known as CBE (computer Based Education). Computers are used to develop computer based training packages, to provide distance education using the e-learning software, and to conduct online examinations.  Researchers use computers to get easy access to conference and journal details and to get global access to the research material. 2. Entertainment: Computers have had a major impact on the entertainment industry. The user can download and view movies, play games, chat, book tickets for cinema halls, use multimedia for making movies, incorporate visual and sound effects using computers, etc. The users can also listen to music, download and share music, create music using computers, etc. 3....

. Digital Computer: A digital computer uses distinct values to represent the data internally. All information are represented using the digital 0's and 1's. Digital signal represents particular state that is: 0 (low) or 1 (high), yes or No, On or OFF, True or False. These systems store and process the data in digital form (string of 0's and 1's). They are capable of processing analog signals but the analog signals have to be converted into digital signals using an ADC before feeding into the digital computer. Analog Computer: Analog computer is another kind of a computer that represents data as variable across a continuous rang of values. Analog computers are used for measuring of parameters that vary continuously in real time, such as temperature, pressure and voltage. Analogue computers are used in hospital to measure the size of stone in kidney and mental disease diagnostics (CT scan with photos). These computer use OP-AMP (Operational Amplifier).
