The word “computer” comes from the word ‘compute’, which means to calculate. So a computer is normally considered to be a calculating device. In fact the original objective for inventing the computer was to create a fast calculating machine. But more than 90% of the work done by computers today is of non-mathematical or non-numerical nature.
Hence, to define a computer merely as calculating device is to ignore over 90% of its work. More accurately, a computer may be defined as a device that operates upon information or data. Data can be anything like bio-data of various applicants when the computer is used for recruiting personnel, or the marks obtained by various students in various subjects when the computer is used to prepare results, or the details (name, age, sex etc.) of various passengers when the computer is employed for making airline or railway reservations, or numbers of different types in case of application of computers for
scientific research problems, etc. Computer Applications in Business By Anil Kumar Pdf
