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.

Before having computers as we know nowadays, we started by having tools for claculating in this order: bones---more efficient than abacus But the 4 generations of computers devoloped like this by adding functions and making everything easier and not so big: bacium tubes - It was very hard to work with them, because there were thounsands of them, if one stopped working you could lost the thing you were doing, changing them, i think was the most difficult part, becuase you had to watch all of them and see the one that was nopt working. transistors transistors, were better, they look like big usbs that had thousands of bacium tubes. it was easier to use a computer, but it was very expensive. circuit integrated - it was better than transistors cause it was integrated to the computer it was faster and easier to work with it but it was also very expensive. microprocesor- its the most advanced device
 * abacus---china---simple for making basic operations
 * pascallin calculatorhis father profession had to do with calculationthis worked like KMadd and substract
 * then another calculator was invented, but now used the binary system and could multiply
 * Francepunch cardsthey were fo storage of information
 * lady lovelase---the first programmer
 * Charles--had the idea of a machine that was the size of a football field...it was a good idea but in those times they didnt had the technology to create it.
 * IBM--
 * HP--

I think is a little bit difficult to define if we really are in a fifth generation of computers because of course we have had many advance in computers and thechnology but in some cases they have the same function but now its easier and portable for example the transitors they had the same function of the Usb´s but the technologies were different. So we have improved technologies which already existed as transistors which now are used to create USBs which make it easier to use and to storage information with a much bigger capacity and in a very short time. Now everything is being modernize and technologic things have more modern uses like a cell phone with internet or a GPS that can save information very big like maps from many places. I think we are close and we are like opening the fifth generation with new stuff. We are starting the 5th generation, because compared to other times, now is easier to create new devices and machines, we have more technology, and it is more suportted, in other times if you wanted to create something new, you had to create it by your own as the team of Apple, but now you just present your idea and you may be lucky so that an enterprise wants to create it. Nowadays, almost everything is controled and we depend on technology, we have enter to a generation in which technology is important and supported.
