Without the revolution of 4004, the PC would not have happened

Introduction

Many important technological changes were not the kind of great transformation, created finally recognized. The use of this technology comes to change them on the road. Not many people can see the extensive use of telephone or radio. There were no buyers for the telephone, Alexander Graham Bell, the company had started has grown to be known as Ma Bell. IBM has a reputation to say anything to get what we have to have five, maybe half a dozenComputer! The personal computer, I will discuss here are used by millions today. Each of these machines is much more powerful than the original computer that caused the comment. The history of the PC through the twists and turns, and started with something That no one really recognized as a powerful force, the way they are today, many things have changed.

History 4004/MCS-4

The story begins with the announcement of a micro-programmable computer on a chip.Intel saw a very small computer in order! The project comes within the efforts of Intel as a chip design for print Busicom 141pF, with programmable calculator. The three participating designers chose Marcian Ted Hoff, E., Federico Faggin and Stan Mazor, a number of chips, which were very general and could INNATURA to create specific functions programmed. Sun shone on the MCS-4 chipset, which includes the 4004 processors. This was a 4-bit CPU. It 'been away from16, 32 or even 64-bit processors. But death was kind of casting.

The chipset barely survive. The name of the chipset of the bankruptcy order. Fortunately, Intel has had a blurred vision of something bigger branch, and the right to manufacture and sell the chip sets for themselves. Good thing they did, even if you do not know where exactly to use the chip. And 'positioning of the chip as an alternative for flexible digital design to do. Intel will start selling this as a replacement forRandom Logic (logic chips discrete logical product).

There followed a flurry of multiple versions of processors. After 4004 came the 4-bit 4040, then used the 8-bit-8080 We also had a 8085th Next to arrive was a processor, another milestone. It 'was the diffusion process that the gap 8 and 16 bit processor. Has 16-bit internal calculations but can communicate with the outside world in 8 bits.

Micro-computers to personal computers

By8085 times arrived at the scene, many people began to take the computer in effect from them and called micro-computer. It 'was another milestone that has influenced the history here. A company called Digital Research came up with an operating system called CP / M and that these micro-computers have made useful. Use began to grow the volume of these machines began to appear and some of the productivity tools of today. word processing, spreadsheets were used asThe applications on these computers.

Then, a different transformation. IBM has decided to make a micro-computer from existing components, subsystems, and decided to let others clone system. This was the beginning of the PC revolution. It was the 8088 processors and a fixed scale bus connecting the motherboard and daughter card combination to add / improve the suburbs, etc. were part of the design. They come from a company called Microsoft operating system. There was a furtherAccident here, that changed things considerably. IBM and Microsoft and IBM ended eventually broke with the Microsoft operating system.

What would be the end of Microsoft, but the attack of the clones IBM-compatible or had a huge volume and the operating system MS has been a decline in PC-DOS MS-DOS and Microsoft created not by repentance. PC generations of Intel processors designed, developed. DOS, Windows has gone throughvarious versions of Vista and has been and now we get Windows 7. Millions and millions of clones were everywhere in our lives. Work or at home, they were everywhere!
