Ex1+T1+Question+2

 2. Describe the 4 generations of computers. (Use examples and descriptions of how the computers were and worked in each one). Do you think we already are in a fifth generation? If so explain on what you base your statement, give examples.

1st generation: In the first generation an object called vaccum tube was primarily used, this storage device had a low amount of memory, vacuum tubes were not long-lasting and had to be changed very often. computers needed 19000 vaccum tubes to work. First generation computers were completely huge, they occupied more than one room; even a single image needed a lot of vacuum tubes. Another characteristic of this computers is that they were very slow and saving information was not very secure. This computers were incredibly expensive. An example could be the ENIAC computer, which was invented by Jonh Von Neuman. This computer made complex equations but occupied 4 floors of a building

2nd generation: In this generation a new device was created, the transistor which substituded the vacuum tubes, this new device made computers much smaller, and cheaper. information was saved in a more secure way and for the first time computers started to be owned by private enterprises.yet, computers were still being huge, as the size of a modern refrigerator.

3rd generation: Integrated circuits were invented, this meant that in only one integrated circuit we could have thousands of transistors, this again made the computer cheaper, faster and smaller, also it meant that a computer could have more functions than before

4th generation: In 1974 intel invented the micro procesor, what take down the used old transistors, or integrated circuits. This new procesors can store a lot of information in a really small object. In this the first personal computer was invented by Apple. For this time Apple worked in the garage of the creator: Steve Jobbs with the help of Steve Wozniak, a micro procesor is smalle than a finger nail and it made computer available for everybody (personal) and obviously cheaper, faster and more usefull.

we also believe we are at the begining of a new computers generation, because there are some new computers, that you no longer need a mouse to move through the screen; you can actually use your fingers to work, as if you had a mouse. Steve Jobs, have just show to the world the new creation 'he has made': a computer, with the format of an iPhone. That means that you'll no longer need a mouse, nor a typer. For us, it seems extraordinary the incredible speed, in which technology has been growing in the last fifty years, because if we look back from where we started, it is actually a radical change. Technology will continue growing, and suddenly we won't be anymore in the fifth generation, we will be in the sixth one, and further. For the new century, much more advanced and sofisticated micro procesors has been created by INTEL. Now personal computers are everywhere and in a sense more beautifull and stylish. We believe that we are th 5th generation but still not very ahead, because micro procesors are as small as they can get and instead what we are doing right now is just adding microprocesor instead of reducing side, we have computers that have much more functions and also they are more stylish, now a gays we not necesarily need a mouse because we can use our fingers, we can save more information and create more things.
