Q. Illustrate the history of computers?
Let's now consider history of computers since this will give fundamental information about technological development trends in computer in past and its projections for future. If we want to know about computers completely then we should look at history of computers and look in details of different intellectual and technological breakthroughs. These are necessary to give us feel of how much effort has been done in past to bring computer to this shape. Our attempt in this part will be to explain the conceptual breakthroughs in past.
Ancestors of modern age computer were mechanical and electromechanical devices. This ancestry may be marked as far back as 17th Century when first machine capable of performing four mathematical operations which are subtraction, addition, multiplication and division appeared.
