A Brief History Session About The Computer And How it Has Developed Through The years

A computer is an electronic machine that has the capability to accept input, store, recall and process information to give an output in a readable format. But in earlier times, a working laptop or computer meant a person performing mechanical calculations under the supervision of a mathematician.

To appreciate the future, we will want to look at history. The history of computer systems can be traced back to Babylonia, where the abacus was born about 200 centuries ago. The abacus is really a wooden frame holding two parallel rods wherein the beads are strung. It had been used as a calculating tool by ancient society. In the year 1642, Blaise Pascal built the initial digital computer. He created his calculator to assist his father, who was a tax collector at the time. Numbers were entered using dials, and it provided an answer as precisely as when calculated by using mathematics. Today, the fundamental theory of Pascal’s computer remains to be being employed in various applications such as odometers and water gauges.

In 1822, an English mathematician going by the name of Charles Babbage developed the first programmable computer. He had a theory that arithmetic tables could be computed and programmed mechanically. So he built a computing machine and called it the difference engine. Babbage’s different engines were among the very first in its category of mechanical computers. Although his machine was unwieldy, its construction was analogous to an up to date computer. It could follow instructions; there was a separate data and program storage, and it had a detached input and output unit. However, Babbage’s machine was not really finished because of economic problems and some other issues. You can find a recently constructed version of the difference engine in the Science Museum in London.

The evolution of punched cards provided an important leap towards computing automation. In 1890, Herman Hollerith and James Powers used these cards with computers. They had made improvements on devices that could interpret the data contained inside the cards with little intervention from humans. As a result, work efficiency increased, and reading mistakes were greatly reduced. Additionally, these punched cards could be utilized as a storage memory of nearly infinite range.

World War II created a need for greater computer power which was to become utilised in military applications. John Eckert and his colleagues in Pennsylvania built an increased capacity electronic computer to serve this purpose. This computer was called the Electrical Numerical Integrator and Calculator or ENIAC. It was an all-purpose computer but of nonflexible construction.

It goes without saying, Alan Turing, Gordon Welchman, Max Newman and Tommy Flowers were key individuals in developing the computer at Bletchley Park. Colossus was designed for code-breaking but greatly progressed the advancement of the modern PC as we know it nowadays.

Computer designs of the ’50s were mostly valve-driven (vacuum tube). They were far better in performance than their earlier predecessors, but they were bulky and costly to produce. Transistor-driven computers were developed during the ’60s, which effectively replaced valve-driven computers. These transistorized computers were faster, smaller in size and much more importantly, less expensive.

During the 1970s, the integrated circuit became widespread and was widely used as the primary electronic component for computers. It paved the way for the mass production of computers, making them affordable not only for companies but also for private individuals. This led to the birth of personal computers. Since then, computer technology has developed exponentially to the point where now we have powerful computers in the palm of our hands. The smartphone, obviously! But they still break down; when that happens, we call on an experienced IT support service. They might not be able to mend Colossus, though…

Naturally, this is only my own opinion, and you can find numerous ebooks and such stuff on the subject that you can find on the internet. I do finHowever, d the history of electronic gadgets interesting. For a company who is up to speed with things like this I always go to computer repair London. They do not just repair computer systems. They are always helpful if you get stuck on any computer problems as well.
