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.

The first generation of computers were the vacum tubes, that they were the ones that process memory, they were very big, this cause that the first computers have a very big size. This vacum tubes cause that this computers were very expensive. The vacum tubes needed to be placed in a binary order in so that they could make the programing; also because the vacum tubes were made like in a series circuit, if one couldn't work anymore the computer couldn't work, until the person replace the Vacum tube that was damage to make the computer to work.

The second generation of computers where the ones that use transistors, this devices werent as big as the vacum tubes so this cause that computers were smaller and cheaper, in this time computer industry appears. This computers where mainly for buisnes enterprices as they require a lot of mainteinance, a big space and a high understanding of the way this computers worked; this computers were sold separatedly, you needed to bought the CPU, the input and output device and memory apart.

The third geneartion of computers were the integrated circuits, this integrated circuits can have more than 6000 thousand of transitors in a small procesing memory, this also caused that computers were even more cheaper and faster and lead to the begining of the personal computer(PC) era

The fourth generation of computers were the microprocesor, the first microprocessor was invented by intel it was the 8080, this make intel the principal microprocesor industry in those times, nowadays intel still being the leader in microprocesors by bringing to the marke the intel "pentium4", "centrino" and "core 2 duo".

I think that we are in the fifth generation of computers because now a days we have very small computers, that are thousands of times better than the ones that existed in the past. Now a days computers have the microprocesors intel centrino Core Duo this makes the computer a very useful device, also now a days we have the tools and the knowladge to make new and better computers, like now there are computers that are touch screen that they don't need a key borad or a mouse. An interesting fact about the first generations of computer was about the famous word "bug" which is used now a days to express that there is something not working on the computer, in the past this was used due to the fact that bugs may sometimes damage the computers because they were inside the computer making their families and reproducting, the computers were their home. But what i really think that bring us to the fifth generation is that now we are able to connect to internet wireless and almost in any part of the world with the new 3G technology.
