Why Computer is call Computer?

 کمپیوٹر کو کمپیوٹر کیوں کہتے ہیں؟
The Word "computer" comes from "compute" witch means to calculate. So a computer is normally consider to be a calculating device that can perform arithmetic operations at enormous (Great,Large,Huge) Speed.

 The term "compute" has been around a long time, meaning to "devise an answer to a problem by evaluating data, following a prescribed series of steps, and arriving at a logical, probably correct answer."
In the 40's, women (and to a lesser extent, men) were hired by the government to endlessly work out mathematical problems for figuring artillery trajectories, and they were actually called "computers"...
In fact, the original objective for inventing the computer was to create a fast calculating machine,but more than 80% of the work done by the computer today is of non-mathematical or non-numerical nature.Hence ,to define a computer merely as calculating device is to ignore over 80% 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 marking airline or railways reservations.
Thus data comes in various shapes and sizes depending upon the typed of computer application.A computer can store,process,and retrieve data as and when desired.The fact that computers process data is so fundamental that many people have started calling it a data processor.
The name data processing is more general because modern computers not only compute in the usual sense but also perform other functions with the data that flows to and from them.For example, data processors may gather data from various incoming sources, merge (process of mixing or putting together) then all,sort (process of arranging in some sequence, ascending or descending) them in the desired order and finally print them in the desired format.None of these operations involve the arithmetic operations normally associated with the computing device,but the term computer is often applied.
