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

It started with the use of abacus during 200 BC

First generation- 1940-1952 : was created for military uses, it wasn´t very sustainable, it was not economical, it was the size of a football court or a university, it had low access speed, it produces a lot of heat, had small capacity of memory and limited capability of programmes running. It consisted of Electron tubes.

Second generation-1952-1964: was used mainly for military and governmet issues, its size was of a big corporation or university. It was faster than the first generation, produced less heat. It consisted of trancitors.

Third generation- late 1960's and 70's: had an Integrated Circuit (created by Robert Noyce),was smaller, had the size of a refrigerator or closet, had a higher capacity of almacening information(100o trancitors). This was used by more people, not just goverment, there were also companies and universities taht used them. During this period Apple began to develope and revolutionized computers: -Apple I -Apple II -Apple Liza -Macbooks -Mac Air

Fourth generation- 1971: it had integrated a microprocessor, which was created by Robert Noyce, it was easier to use, was much more smaller, had grater storage capacity, was cheaper so almost everyone could buy one. This generation was starting to be more for a regular uses for regular people . Fifth generation- computers began to be wireless (internet). This is now a days technology. This was a major change because now in the 21 century we mostly use computer to browse in the internet, and many things that used to be manual were substitute by technology thanks to the internet. Computer types 1. Analog used a physical force liek nuclear energy and fluid pressure 2. Digital used binomails 0 and 1 and was used for arithmetics 3. Hubrid was a combination of both digital and analog with more improvements

More categories 1.microprocessors? smallest uni of cumputers alive 2.miniprocessors 3.microcomputers 4. super computers biggest computers, very costly, used for scientific purposes and arithmetic purposes

Robert Noyce invented the Integrated Circuit which he later used for printing He was a physicist who was married by the age of 28

- Augustana Byron -Chris babbage Both contributed to a big part of the initiation of computers
