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 was a primitive one, but it was an inovation, in fact the first computers ocuppied the space of three floors of a bulding, where the inforamation wis given by a paper with dots and the space is for the memory. The first computers functioned with vaccum tubes, this are little artifacts with the form of a bulb, their work was to save information but they were really problematic because if one stops fuctioning really fast and they would need to check one until they find the one that doesn´t work.With the first and two generation computers worked with many vaccum tubes in which each one have two binare numbers, so that is why this types of computers were so big, because the memory is saved with a binary system in wich there is only a 0 and a 1, so letter a can be "01" leter b can be "010" so imagine the long information how many memory stiks will need. After the vaccum tubes they realized that it was quite difficult to mantain them, and they didn´t have space for lots of information that is why they invented the transistors, this were little artifacts( more little than the vaccum tubes) that have the capacity to save lots of vaccum tubes, this was a great inovation. After the transistors they wanted alaso more memory that is why they made the circuits integrated, this were also little artifacts that could save the capacity opf lots of transistors so imagine the thousand vacume tubes saved in one transistor, now imagine a thousand transistor saved in the space of one small device. Microprocesors goes next, they were even better than the integrated circuits, because they could store much more information, they have millions of transistors, in comparisson with the integrated circuit, they had thousands. the laste generation were the microprocessors, in wich the memory occupe 6000 transistors, remember each trasistor heve 4 vacum tubes and each vacum tube have a binary number. As computers started to evolve, they started to become smaller, cheaper and faster. They became cheaper because the job of building up a computer was not that hard and long,. With the new technology and with the new artifacts they became faster, and they became more comfortable because they were not so big. We believe that we are in process of a fifth generation because of the new tecnology, for example not only microprosersors anre made with bigger memory, also touch pads , sounsd commands and even more bigger memory spaces mor even more comands in such a small computer that help the user to have more interacion with the compuuter itself, to ftouch it, move it, feel it. there will always be more generations, because, as time passes, life evolves, and the human keeps looking for an easier way of life and the human being is never satisfied, so we will keep evolving, and creating better and new technology.
