The Information Age

What is the Information Age? People, Information & Societies that chronicle the birth and growth of electronic information -- from ancient times to Samuel Morse's invention of the telegraph in the 1830s, through the development of the telephone, radio, television, and computer. http://www.tcf.ua.edu/AZ/ITHistoryOutline.htm Different ways of looking at computer evolution…. J Butler at university breaks it down like this… http://www.tcf.ua.edu/AZ/ITHistoryOutline.htm (updated link) White page @ http://www.computersciencelab.com/ on history of computers very helpful

Four Periods of The Information Age Pre-Mechanical - 3000 B.C.-1450 A.D. Mechanical - 1450-1840 Electro-Mechanical - 1840-1940 Electronic/Information -1940-Present Pre-Mechanical—People not machines, nothing automated http://www.computersciencelab.com/ComputerHistory/History.htm

The Pre-Mechanical Age 3000 B.C.-1450 A.D. Writing and Alphabets: Cuneiform, Symbols Paper and Pen: Papermaking Books and Libraries: Religious Scrolls, Binding Numbering Systems: Numbers 1-9, Zero The First Calculators The Abacus Cuneiform script (pronounced KEW-ni-form) http://www.tcf.ua.edu/AZ/ITHistoryOutline.htm http://www.computersciencelab.com/ComputerHistory/History.htm What about Tally Sticks? 35,000 BC ? http://en.wikipedia.org/wiki/Tally_stick

The Mechanical Age Movable Type Printing 1450-1840 Movable Type Printing General Purpose Computers (people who used numbers) Slide Rule Analog Computer Key Punch Computer Binary Logic Real Time Operated Computers This slide needs fixing! This slide isn’t even supported by the outline this is supposed to come from http://www.tcf.ua.edu/AZ/ITHistoryOutline.htm I haven’t really found a good link that repeats these ages or timeframes. The first use of the word "computer" was recorded in 1613, referring to a person who carried out calculations, or computations, and the word continued to be used in that sense until the middle of the 20th century. http://en.wikipedia.org/wiki/History_of_computing_hardware Analog Computer http://en.wikipedia.org/wiki/Analog_computer http://www.tcf.ua.edu/AZ/ITHistoryOutline.htm http://www.computersciencelab.com/ComputerHistory/History.htm http://www.computersciencelab.com/ComputerHistory/HistoryPt2.htm http://en.wikipedia.org/wiki/Jacquard_loom

The Electro-Mechanical Age 1840-1940 Telecommunications Voltaic Battery Telegraph Morse Code Telephones and Radios Computing Census Machine Mark 1 Paper Stored Programming http://en.wikipedia.org/wiki/History_of_computing_hardware Exam Telephones and Radios Picture of a 1986 Telephone from Vendsyssel Historiske Museum in Hjørring, Denmark © 2004 by Tomasz Sienicki Picture of a 1986 Telephone from Vendsyssel Historiske Museum in Hjørring, Denmark © 2004 by Tomasz Sienicki

Information Age Electronic Vacuum Tubes 1840-Present Electronic Vacuum Tubes Electronic Numerical Integrator and Computer Manchester Mark 1 First Computer for Commercial Use Needs to be fixed: Doesn’t really translate from outline well here http://www.tcf.ua.edu/AZ/ITHistoryOutline.htm

Computer Generations First Generation (1951-1958) Main Logic Elements Externally Stored Information Machine and Assembly Language Compilers Second Generation (1959-1963) Transistors Semi-Conductors High-Level Programming Fortran/Cobol Third Generation (1964-1978) Integrated Circuits Magnetic Tape and Disk Operating Systems BASIC Fourth Generation (1979-) Large Scale Circuits Central Processing Units Apple II/Apple Mac IBM/MS-DOS/GUI MS Windows Needs to be fixed! Again doesn’t really translate from outline well here Exam Question: Third Generation (1964-1978) BASIC

Pioneers in Information Technology John Mauchly J. Prosper Eckert John Von Neumann Blaise Pascal William Oughtred Gottfried von Leibniz Charles Babbage Augusta Ada Byron Alexander Graham Bell Herman Hollerith Howard Aiken Max Newman Maurice Wilkes Steven Wozniak Steven Jobs Bill Gates The last 3 names are the only ones mentioned on Pioneers in Info Technology activity.
