Programming skills

  1. 1. Programming Skills: A look back to peer into the future.Pete MassielloiTech Solutionspmassiello@itechsol.comTwitter: PeteM59 1
  2. 2. Prehistory• The first Programming languages predate the computer.• Languages were codes• 1890 Herman Hollerith – Census data
  3. 3. Early programming
  4. 4. When do we start?• The Analytical Engine, an important step in the history of computers, is a design for a mechanical general-purpose computer first described by English mathematician Charles Babbage in 1837. It was the successor to Babbages difference engine, a design for a mechanical calculator. The Analytical Engine incorporated an arithmetical unit, control flow in the form of conditional branching and loops, and integrated memory, making it the first Turing-complete design for a general-purpose computer.• Programming supposed to be by punch cards.
  5. 5. Analytical Engine: Built 63 years later
  6. 6. ENIAC• Designed in 1942 General-purpose Electronic computer• Electronic Numerical Integrator and Computer (ENIAC).• Enormous speed advantage by using digital electronics with no moving parts.• Called Project-PX as its code name.• Started in 1943, completed in 1946 costing $500,000 ( $6,000,000 in 2010 dollars).• Designed to calculate artillery firing tables for the Army.• First project was computations for the hydrogen bomb.• Decimal based.
  7. 7. Programming the ENIAC
  8. 8. Operating ENIACs main control panel
  9. 9. EDVAC• Electronic Discrete Variable Automatic Computer• Binary serial computer with automatic addition, subtraction, multiplication, programmed division and automatic checking with an ultrasonic serial memory.• Capacity of 1,000 44-bit words, later set to 1,024 words: 5.5KB• 6,000 vacuum tubes, 12,000 diodes, consumed 56kW of power, and covered 490 Sq. Ft. Weighed 17,300 pounds.• Designed 1946 built and operational 1949.• Magnetic tape (Wire recorder).
  10. 10. EDVAC
  11. 11. What is a Programming Language• A programming language is an artificial language designed to communicate instructions to a machine, particularly a computer. Programming languages can be used to create programs that control the behavior of a machine and/or to express algorithms precisely.• The earliest programming languages predate the invention of the computer, and were used to direct the behavior of machines such as Jacquard looms and player pianos. Thousands of different programming languages have been created, mainly in the computer field, with many more being created every year. Most programming languages describe computation in an imperative style, i.e., as a sequence of commands, although some languages, such as those that support functional programming or logic programming, use alternative forms of description.
