  1. COMP 1321 Digital Infrastructure Richard Henson University of Worcester September2018

  2. What is this module about? • All Higher Education modules required students to reach a number of LEARNING OUTCOMEs (LO) • LO1: Describe a range of digital platforms and networks and explain the context for use of each platform • Assessed in assignment 1 • LO2: Apply tools involving digital hardware and digital logic to solve real world problems • Assessed in assignment 1

  3. More LOs • LO3: Explore the contents of a digital storage medium using computer forensic software and extract information that could be used as evidence • assignment 1 • LO4: Apply networking principles to provide connectivity between digital devices on a range of platforms that can be used for sharing data and control of processes • assignment 2 • LO5: Use penetration testing software, in accordance with relevant standards and legislation, to identify vulnerabilities • assignment 2

  4. Lets start at the beginning… • What is a computer? • In small groups… • Four attributes of a computer… • What is it? • What does it do? • 10 minutes…

  5. History of Ancient Computing machines • When did the first computers get built? • 3400 BC: counting in tens (Egypt) • 2600 BC: Abacus (China) • 1900-1600 BC: Stonehenge completed • 260 BC: base-20 counting – including zero (Maya – Central America)

  6. Using those attributes…Are these computers? • Abacus TypewriterBathroom scales Car speedometerThermostat Stonehenge Pocket calculator PersonDVD player Microphone

  7. Abacus

  8. Stonehenge

  9. “Modern” Calculating Tools… • Around 1500: Design of mechanical calculator (Leonardo da Vinci) • 1614: Logarithms (John Napier) • 1621: Slide rule (Edmund Gunter, William Oughtred)

  10. Types of slide rule

  11. (European calculating machines – continued) • 1642: Adding machine (Pascal) • 1679: Binary arithmetic (Leibnitz) • 1820s and 1830s: Charles Babbage’s Difference Engine and Analytical Engine

  12. Babbage… • Analytical engine as reproduced in Sweden: • http://w1.131.telia.com/~u13101111/merschwib.html

  13. Boole: inventor of “digital” • Would be 203 years old this year… • https://www.youtube.com/watch?v=w_5G6yLTR6U • Work buried from his death (1864) until the 1930s…

  14. Boolean Algrebra • 1840s George Boole… • Whole new system of Algebra • used true/false instead of numbers • trying to produce a type of maths that related to philosophy • Inspiration for all of us!

  15. Programming • Started with Ada Lovelace • daughter of Lord Byron • Brought up on Maths (!) • Developed a friendship with Babbage • Wrote instructions for his machines…

  16. European Domination of Hardware (mostly British) • 1835: Electric Relay (Davy) • 1904: Vacuum tubes (“valves”) birth of electronics (John – not Alexander - Fleming) • The Second World War • 1936: Programmable computer (Konrad Zuse, Germany) • 1943: Colossus, UK, based on relays • Tommy Flowers, telephone engineer. Won the war?

  17. Colossus – what’s that! • Top secret code breaker … 9000 people worked at Bletchley Park during ww2… above, two of them… • http://www.bbc.co.uk/programmes/p031vdwf • http://www.youtube.com/watch?v=46SI79feHT4

  18. Bletchley Park (shhh… Top secret!) • Set up in 1940 to crack German codes… • succeeded… • thanks to Turing “bombe” • Flowers “Colossus” • Others? • estimated that war shortened by 2 years!!!

  19. An Enigma • Bletchley Park helped win the war • no-one could talk about it! • 40 year silence! • In 1985 one of the great codebreakers wrote a book… • but authorities disapproved, made his life difficult, and he died young. Name: Gordon Weichman: • http://www.bbc.co.uk/programmes/p031vg47

  20. A Curiosity… • Boole’s work was admired by de Morgan (1840s) • Lovelace received encouragement from de Morgan (1830s) • Yet Boole and Lovelace never met • Both died young • thankfully, their work made them immortal

  21. Like to go to Bletchley Park? • https://bletchleypark.org.uk/ • Includes a museum of Computing • Could be arranged as an all day visit…???
