Question2: Create a time line of the history of computers using the handout information and Robert Noyce documentary (no dates necesary

0.Bababbage made one of the biggest improvements in all the history of computers: He invented the analitical language with the aid of punchcards that were invented by Jacquard. 1. First generation computers were huge as football fields, produced a lot of heat. They worked thorugh electron tubes. This computers were used by universities and the goverment only. 2. The second generation of computers worked with transistors (invented by Shockley and other guys) and was somehow more effective than the first generation of computers, howewer it still produced lots of heat. It was used in the goverment and universities but started being used in business. 3. Shockley and Noyce tried to invent a silicon transistor, but after Shockleys nobel prize winning the idea is dissmised. Eight group of people including Noyce left Shcockley and they came to be called the eight traitors, they went with Fairchild asking him for money, and he accepted with the condition that he could stay with the company in case of success. 4. Fairchild semiconductors invents the silicon transitor (that is cheaper and easier to be built) but its not satisfied yet, and starts working in a new way to construct a whole circuit. 5. Demand for resistors increased as the prices are lowered 6. Noyce and Kilby invent at the same time the integrated circuit(which is like thousands of transistors in one single chip), with the difference that, the Kilby invented it with germanium and noyce with silicon. Still both are considered the discoverers. 7. Noyce has to start a campaign to sell integrated circuits since its still cheaper to get circuits made by resistors. 8. Computers start using integrated circuits, they are fridge size and more effective, this would be the the third generation computers, however integreted circuits dont have a single function and the prize is still somehow high. However they are easily used by enterprises as IBM 8. Noyce leaves fairchild and forms INTEL with Mr. Moore. 9. Due to an idea of one worker, they start developing the idea of a microprocessor. It was originally presented to japanese people but they rejected it, therefore INTEL could work on it and develop it. 10. In 1971 they were able to create the microprocessor, at the beggining the microprocessor Itanium was used for the fourth generation computers, and due to this the computers could carry out more instructions easily, however as time passed by this microprocessor was developed, it was small and formed part of the last generation of computers (the ones we use nowadays). 11. 1975 altair 5000 started working with a very BASIC language made by Bill gates and Paul Allen. 1. In 1976 Apple computers are created by Wozniac and Jobs, and lead to the great expansion of the already existing Silicon Valley and the new reformation of computer history, the one concerning software. 12: 1977 Apple II 13. 1983 Windows is launched 14. 1997 internet explorer is launched and the interntet/computer boom started. :D
