History of computers

How did computers came into existence?The history of computers is quite interesting.Imagine that you have a job where you have to perform nothing but calculations every day-at one point of time you will get bored.You might even become careless and start making mistakes.This is the reason inventors came up with something that would automate the task of performing calculations.
The chinese Abucus was one of the early inventions that helped humans perform mathematical calculations.After the invention of a multitude of diverse devices such as the jacquard loom(1805)and charles babbage's "analttical enigine"(1834) calculating machines evolved into the modern computers that we see today.In the initial days when electronic computing devices first came into use,there was much difference of opinion in the relative merits of analog computers  over digital computers.In fact even by the end of 1960s only analog computers were used for solving systems having finite difference equations.As more time passed users realized that digital computing devices had the economics,power  and scalability which were needed for dealing with large-scale computations.Starting from simple hand had calculators to supercomputers,today,s world is dominated by digital computers.
