so didn't get time to post a summary on thursday, but here it is now.
so i rocked up late and we had a new lecturer, who decided to give us a brief 1 hour history into the life of computers ha. From the garage nerds to massive company production of pc's.. it was intresting to say the least.
Here's a timeline!
- Charles Babbage"s 19th century Difference Engine (designed to calculate and print mathematical tables)
- Ada Byron, Lady Lovelace, annotated her own translation of an Italian article about Babbage, Sketch of the Analytical Engine, first conceived of a machine which would be able to compose and play music, produce graphics and be of everyday use. She also conceived the first computer program.
- Alan Turing, wrote a crucial paper clarifying the computability of numbers and the possibility of a machine to compute them, On Computable Numbers.
- Turing worked with teams of mathematicians and cryptographers to devise the first working computer, The Bombe which they used to break secret German "Enigma" codes during the war.
- After the War, Turing investigated programming, neural nets, and the prospects for artificial intelligence.
- Computers were first commercially produced by IBM in the 1950s.
- 1965, Gordom Moore propounded Moore"s law: the capacity of microchip"s doubles every two years.
History of the Internet:
1957:The United States Department of Defense formed a small agency called ARPA (Advanced Research Projects Agency) to develop military science and technology.
1961-1965:The Massachusetts Institute of Technology (MIT) started to research sharing information in small, phone-linked networks. ARPA is one of their main sponsors.
1966: The first ARPANET plan is unveiled by Larry Roberts of MIT. Packet switching technology is getting off the ground, and small university networks are beginning to be developed.
1969:The Department of Defense commissions the fledgling ARPAnet for network research. The first official network nodes were UCLA, Standford Research Institute,UCSB, and the University of Utah. The first node to node message was sent from UCLA to SRI.
1971: more nodes join the network, bringing the total to 15. These new nodes include Harvard and NASA.
1973: ARPAnet goes global when the the University College of London and Norway's Royal Radar Establishment join up.
1974: Network intercommunication is becoming more sophisticated; data is now transmitted more quickly and efficiently with the design of TCP (Transmission Control Program).
1976: Unix is developed at AT and T; Queen Elizabeth sends out her first email message.
1979: USENET, the mother of all networked discussion groups, is developed.
1982: Internet technology protocols are developed, commonly known as TCP/IP (Transmission Control Protocol and Internet Protocol). This leads to one of the first definitions of an "internet" being a connected set of networks.
1984: Number of hosts is now up to 1000, with more being added every day.
1985: The first registered domain is Symbolics.com.
1987: Number of hosts breaks the 10,000 mark.
1988: First large-scale Internet worm affects thousands of Internet hosts.
1991: Tim Berners-Lee develops the World Wide Web.
1993: The World Wide Web's annual growth is now at a staggering 341,634%.
1994: ARPAnet celebrates 25th anniversary.
1995-1997: RealAudio introduces Internet streaming technology, dial-up systems emerge (America Online, Compuserve), the Internet backbone continues to be strengthened with the addition of MCI, Microsoft and Netscape fight for WWW browser supremacy, and there are now more than 70,000 mailing lists.
1998-present:The Internet continues to experience staggering growth. More people use the Internet to get connected to others, find information, conduct business, and share information than ever before in history.

But hopefully we are onto a new topic next week.
