The Word "Computer" comes from the word "compute", which means "to calculate". Hence, people usually consider a computer to be a calculating device that can perform arthmetic operation at high speed.
In fact, the original objective for inventing a computer was to create a fast calculating machine. However, more than 80% of work done by computers today is of non-mathematical or non numerical nature.Hence, to define a computer merely as a calculating device is to ignore over 80% of its function.
Hence, data comes in various shapes and sizes depending upon the type of computer application. A computer can store, process, and retrive data as and when desired. The fact that computers process data is so fundamental that many people have sarted calling it is a data processor.
The data processor more inclusive because modern computer not only compute in the usual sense but also perform other function with data that flows to and from them.The activity of processing data using a computer is called data processor. Data processor consists of three sub-activites : capturing input data, manipulating the data, and managing output results. As used in data processing, information is data arranged in an order and form that is useful to provide receiving it.Hence data is raw material used as input to data processing and information is processed data obtained as output of data processing.
