1. What is Computing?

2. Computing Any goal-oriented activity requiring, benefiting from or creating computers Computer: a device that can be programed to carry out a finite set of arithmetic or logical operations, typically requires automation What do this include?

3. Computing Early Computers Jacquard Loom – Created complex weaving patterns such as brocade – Programs were made on “Chains of Cards” An early version of punch card programing. Primarily mechanically based.

4. Computing The Difference Engine Mechanical Calculator developed primarily to deal with polynomial functions Used a series of mechanical columns to perform binary calculations including the carry operation.

6. Computing Ultra and the Enigma World War II Problem – Germans has an unbreakable code generated by a machine Solution – Gather all the smartest people you can find and lock them in a building together Result – Bombes! (Yes that is spelled right)

7. Computing Turing–Welchman bombe Electromechanical machine that could help break Enigma Developed by Alan Turing and Gordon Welchman Used a series of logical deductions to crack the Enigma via a semi-brute force attack Over two hundred in operation by 1945

8. Computing Electronic Numerical Integrator And Computer Fully programmable Turning-complete Used in atomic bomb design Used a set of cords to set the programs All the early programmers for the system were women

9. Computing - 1954 IBM 704 – mass produced floating point computer for commercial use FORTRAN – the programming language used with the IBM 704. Considered the first high level language and an alternative to assembly code. Used core memory and was fully programmable Able to do 400 calculations a second. Modern device run about 10,000 million calculation per second

10. Computing – 1960’s Spacewar! - First known computer game. Two player Moore’s Law Packet switching – lead to network integration Floppy disk Interactive Computing – mouse, windows, and word processing The transistor (Bells Labs) Printed boards

11. Computing – 1970’s Development of RAM (Intel) Unix TI-Whatever’s – first portable calculators First microprocessors Pong released Programming language C is released by Bell Labs – Dennis Ritchie Apple II, Commodore, IBM PC

12. Computing – 1980’s Quantum Computing theorized Symbolic Languages developed GNU Windows launched World Wide Web developed HTTP, telnet, ftp Sound cards

13. Computing – 1990’s Linux Wolfenstein 3D / Doom Netscape 1.0 / AOL Development of Java Hotmail iMac’s

14. Computing – 2000’s Pentium, NVIDA, Mr. Bain’s wasted college years Firefox and Open Source Laptop (Macbook) iWhatevers Steve Jobs Ruby and Python Tablets
