  2. The Internet has a lot of history starting in the 1960’s when the department of defense experimented with a computer network called ARPANET and from that point on it has blossomed into something great.

  3. Main Points -Early computional devices -Early Computers -Generations and main component -Inventors/Developers -Internet

  4. Early Computional Devices • Abacus was used in Asia for performing Asthmatic processes. • Mark 1 Is the enzyme that is in humans that is encoded by the mark 1 gene. • Punched Cards were invented by BasileBouchan in 1725.

  5. Early Computers • ENIAC is a electronic numerical integrates and computer. • EDSAC is a electronic discrete variable automatic calculator. • EDVAC is a electronic discrete variable automatic computer. • UNIVAC is a universal automatic computer.

  7. Continued.. • First microcomputers made up the minicomputers CPU with one integrated microchip.

  8. Vacuum Tubes-Invented by Presper Eckert and John Mauchly in 1946. Transistors- Invented by John Barbeen, William Sheckly, and Walter Brattain in 1947. Integrated Circuit-Invented by Jack Kilby and Robert Noyce in 1946- 1971. Microprocessor- Invented by Ted Hoff in 1971. Artificial Intelliengence- Still in development. Generations and Main Component

  9. Inventors and Developers • Steven Jobs was born February 24th 1955 in California and he died October 5th 2011 of pancreatic cancer. He invented many things and was a part of the formation of Apple computer inc.
