One of the most important developments for the personal computer revolution was the invention of the semiconductor. Or the transistor in 1949. The performance was conducted by engineers at Bell Labs. The transistor was nothing more than a switch to solid state electronics have replaced vacuum tubes much more important day. The transistor consumes much less power in the implementation of the exact spot as the most, the tubes hot day. Such a computer system built with transistors would be smaller, consume less energy and be more effective. And to boot since transistors did not like a tube or electric light bulb, much more reliable.
Transistors led to a trend toward miniaturization, which led all the way to today’s small portable laptop laptops / that can run on batteries. It is difficult to imagine that replacing a laptop today, which would be a tall building with computers that are consumed by the enormous amounts of electricity have been packed.
In 1959, Texas Instruments engineers figured out how to make more than one transistor on the same basis and the connection of these transistors without wires. The next step is born – the integrated circuit. The first integrated circuit composed of only six transistors. Current computers have in the order of 100 million transistor equivalents.
In 1969, Intel introduced the chip 1 k of memory. This was bigger than the product at the time. Through coordination of Intel computer with a Japanese manufacturer called Busicomp the next step was taken, where a generic multi-chip was developed. What made this gesture was important that no one could chip a number of tasks to do. Previously, each chip had a goal that has now burned an inch chip has a number of different functions that could be done. A single integrated circuit was almost a computing device. The followers of this multipurpose integrated circuit or “CPU” was what was on the basis of our generation and the concept of the personal computer /
were developed in 1973, some of these kits computer for the first integrated Intel 8080. In the hands of the amateur, these kits were put together, and were more than flashing lights. However, the momentum was. Many of these early computer enthusiasts went to become giants of the industry. With Intel introducing a more powerful microprocessor chip in the computer industry was on its way.
The first was a pioneering MITS kit company that introduced the kit Altair computer. The Altair inspired to write more business, programs for these first computers. Was among the early innovators and software manufacturers in this area from Microsoft with its first version of “Basic”.
Now things really started moving. IBM introduced the first “personal computer” in 1975. The Model 1500 was also compared to dollar stores today piddly computer and costs only $ 9,000.
In 1976, according to a recent California-based Apple Computer introduced the Apple I computer for $ 695. The original Apple 1 computer was screwed on a motherboard in a piece of plywood. A case and power are not even included, the buyer was also $ 695 for the supply and manufacture.
The Apple I in 1977 followed by the Apple II. The Apple II because of its enormous success in setting standards for almost every computer mic to follow, including the IBM PC.
The stage was not planned for the publication of the next big step in the evolution of the personal computer. The large and powerful computer IBM monolith – a very profitable business and lucrative was from a small upstart, the product began from a very primitive home seems to have screwed a piece of plywood type of product .. embarrassing that you have your laptop and your personal computer – PC itself to me as basic human and weaknesses.
