ENIAC Electronic Numerical Integrator And Computer was born in It was a huge machine with a huge power requirement and two major disadvantages. Maintenance was extremely difficult as the tubes broke down regularly and had to be replaced, and also there was a big problem with overheating. The most important limitation, however, was that every time a new task needed to be performed the machine need to be rewired. In other words programming was carried out with a soldering iron.

Evolution of the Computer

In the late 's John von Neumann at the time a special consultant to the ENIAC team developed the EDVAC E lectronic D iscrete V ariable A utomatic C omputer which pioneered the "stored program concept". This allowed programs to be read into the computer and so gave birth to the age of general-purpose computers.

It used to be quite popular to refer to computers as belonging to one of several "generations" of computer. The First Generation This generation is often described as starting with the delivery of the first commercial computer to a business client. This happened in with the delivery of the UNIVAC to the US Bureau of the Census.

This generation lasted until computer the end of the 's although some stayed in operation much longer than that. The main defining feature of the first generation of computers was that vacuum tubes were used as evolution computer components. Vacuum essays are generally about centimeters in length and the large numbers of them short in computers resulted in huge and extremely expensive machines that often broke down as tubes failed.

The Second Generation In the mid's Bell Labs developed the transistor.

Transistors were capable of performing many of the same tasks as vacuum tubes but were only a fraction of the size. The first transistor-based computer was produced in Transistors were not only smaller, enabling computer size to be reduced, but they were faster, more reliable and consumed less electricity. Who is known as the first computer programmer? Who invented the punched card?

Therefore, many simple devices such as an essay which dates back evolution at least BCE or a slide rule first made in England in the s are the forerunners of today's modern computers.

The first machine that worked like a computer was a gear-powered German device dubbed the Calculating Clock.

It was first created by Wilhelm Schickard inand it operated by pulling or pushing rods set inside a glass case. A similar device known as a Pascaline became popular in the s.

These two devices were the forerunners of a steam-powered "difference engine" that was a pet project of Charles Babbage in the s.
