Many more computer companies were born during this time, and eventually this led to personal computers for everyday use. Almost every computer at least filled an entire room, and most were not any smaller than a van today. In , Alan Turing showed that any problem can be solved by a machine if it can be expressed as a finite number of steps that can be done by the machine www. The first computers were actually nothing more than calculators. They never finished it because of the war.
In , Atansoff finished his small computer he built to test his ideas. He used this model to begin work on his Atansoff-Berry Computer ABC , and was again forced to ground his project because of war. For example, the number five would be Early programmers had a hard time converting to this, so they thought of one as true, and zero as false www. A man by the name of Howard Aiken built the Mark I which had mainly mechanical parts, but had some electronic parts as well.
It used mechanical switches to open and close its electric circuits. It contained over miles of wire, and , parts and weighed well over 5 tons. Aiken would go on to hire one of the most famous females in computer history, Grace Hopper to be the lead programmer of the Mark I. In , John von Neumann wrote a paper telling how a binary program could be stored on a computer.
Babbage continued to work on it for the next 10 years, but in he lost interest because he thought he had a better idea; the construction of what would now be called a general purpose, fully program-controlled, automatic mechanical digital computer. Babbage called this idea an Analytical Engine. The ideas of this design showed a lot of foresight, although this couldn't be appreciated until a full century later.
The plans for this engine required an identical decimal computer operating on numbers of 50 decimal digits or words and having a storage capacity memory of 1, such digits. The built-in operations were supposed to include everything that a modern general - purpose computer would need, even the all important Conditional Control Transfer Capability that would allow commands to be executed in any order, not just the order in which they were programmed.
As people can see, it took quite a large amount of intelligence and fortitude to come to the 's style and use of computers. People have assumed that computers are a natural development in society and take them for granted.
Just as people have learned to drive an automobile, it also takes skill and learning to utilize a computer. Computers in society have become difficult to understand. Exactly what they consisted of and what actions they performed were highly dependent upon the type of computer. To say a person had a typical computer doesn't necessarily narrow down just what the capabilities of that computer was.
Computer styles and types covered so many different functions and actions, that it was difficult to name them all. The original computers of the 's were easy to define their purpose when they were first invented. They primarily performed mathematical functions many times faster than any person could have calculated. However, the evolution of the computer had created many styles and types that were greatly dependent on a well defined purpose.
The computers of the 's roughly fell into three groups consisting of mainframes, networking units, and personal computers. Mainframe computers were extremely large sized modules and had the capabilities of processing and storing massive amounts of data in the form of numbers and words. Mainframes were the first types of computers developed in the 's. Users of these types of computers ranged from banking firms, large corporations and government agencies. They usually were very expensive in cost but designed to last at least five to ten years.
They also required well educated and experienced manpower to be operated and maintained. Larry Wulforst, in his book Breakthrough to the Computer Age, describes the old mainframes of the 's compared to those of the 's by speculating, " Networking computers derived from the idea of bettering communications.
They were medium sized computers specifically designed to link and communicate with other computers. The United States government initially designed and utilized these type of computers in the 's in order to better the national response to nuclear threats and attacks.
The Internet developed as a direct result of this communication system. In the 's, there were literally thousands of these communication computers scattered all over the world and they served as the communication traffic managers for the entire Internet.
One source stated it best concerning the volume of Internet computers by revealing, " By there were over 50, hosts. A year later, there were three times that many" Campbell-Kelly and Aspray The personal computers that are in large abundance in the 's are actually very simple machines.
Their basic purpose is to provide a usable platform for a person to perform given tasks easier and faster. They perform word processing, spread sheet functions and person to person communications just to name a few. They are also a great form of enjoyment as many games have been developed to play on these types of computers. These computers are the most numerous types in the world due to there relatively small cost and size. The internal workings and mechanics of personal computers primarily consisted of a central processing unit, a keyboard, a video monitor and possibly a printer unit.
The central processing unit is the heart and brains of the system. The functions of the central processing unit were based on a unit called the Von Neumann computer designed in As stated in the book The Dream Machine, the Von Neumann computer consisted of an input, memory, control, arithmetic unit and output as basic processes of a central processing unit.
It has become the basic design and fundamental basis for the development of most computers Palfreman and Swade Campbell-Kelly, Martin and William Aspray.

The History of Computers Essay - The History of Computers In order to fully understand the history of computers and computers in general, it is important to understand what it is exactly that lead up to the invention of the computer. After all, there was a time when the use of laptops, P.C.s, and other machines was unthinkable. The history of computers can be divided into generations, roughly defined by technological advances, which led to improvements in design, efficiency, and ease of use. First Generation Computers ()- As the Second World War was about to start, governments sought to develop computers to exploit their potential strategic importance and to help them develop new computerized weapons and new .
History of computers. ENG The volume and use of computers in the world are so great, they have become difficult to ignore anymore.
