 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.

First generation (1951-1958) was vaccum tubes people needed a lot of this devices in order to work and save information in a computer. Each computer could have more than 19000 vacuum tubes in order to work properly. The vacume tubes were like "volves" you needed a lot of them to save information, this make that the computers were so big like the size of a room.

Second generation (1959-1964) was of transistors which replaces vacuum tubes, transistors made computers, smaller, more useful, and cheaper, also the computers that have transistors used less energy than the computers that used vacuum tubes, still they used a lot of energy, enough to overheat the computer.

Third generation used integrated circuts, multiprograming, database management, it started using keybords and monitors. The transistors were miniaturized, what made computers samaller than the ones that just used transitors.

Fourth generation (present) microprocessor chips, central processing unit and silicon chips. The computers were smaller and cheaper, these kind of computers can save a lot of information and are more efficient.

I believe we are not in the fifth generation of technology because we are not advancing that much as in other eras, it is true that we have much more technology, but talking about the contrast in advance and time is much less because we have all the facilities. Also we still use chips and not something new as we have been using all along the different eras. But at the contrary, we can still say that we are in the fifth generation because of the new technology developed by the advances of each era, as an example we can say that even through(no se si sta bn escrito) the small devices that we use for ipods, computers or videogames (meaning the chips) were invented in the fourth generation, we are developing them to become even more usefull and sofisticated as they are. And in this case, we can call this period of time the "fifth generation". What is happening is that we are using the same technology but we are looking for more confort for us making the devices smaller and quicker

I think we are in the beginning of the fifth generation which is using artifical intelligence, but I think even we have improved a lot of our technology we still need a lot of work to make enter completely to the fifth generation because right now, we are in the middle of the fourth and the fifth, i think another thing we need to leave behind the fourth generation is a globalized world in which technology is used by everyone, because actually there are some people and even some countries which don't have as much technology as other countries does. The main aim of the fifth generation is for computers to understand natural language, which in my opinion will simplify a lot people's lives.
