  1. Technologies of the Information Age Team Name: Super Troopers Presented by: Ernest Del Real Jeanette Gerardo Rosa Morales Brian Ly

  2. Five Generations of Computers • Computer Development • Refers to the different generations of computing devices • Each generation is characterized by a major technological development. Brian Ly

  3. First Generation1940 - 1956 • First computer used Vacuum Tubes • Consisted of: • Tubes for circuitry • Magnetic drums for memory • Metal cylinder coated with magnetic iron-oxide material. • Disadvantages: • Expensive to operate • Used great deal of electricity • Generated a lot of heat • Undependable Brian Ly

  4. First Generation Computers • Relied on machine language • Solve one problem at a time • High-level programming languages • Assembly language • Used assemblers and compilers • CPU had their own unique language Brian Ly

  5. Second Generation1956 – 1963 • Transistors replaced vacuum tubes. • Transistors are devices composed of semiconductor material that amplifies a signal or opens or closes a circuit. • Transistors invented in 1947. • Advantages: • Superior than vacuum tubes • Smaller • Faster • Cheaper • More energy-efficient • More reliable Brian Ly

  6. Moved from cryptic binary machine language to symbolic. • COBOL and FROTRAN • First computers that were developed for the atomic energy industry Brian Ly

  7. Third Generation1964 – 1971 • Integrated circuits • Hallmark of the third generation • Drastically increased speed and efficiency of computers. • Keyboards/Monitors interfaced with Operating Systems. • Advantages: • Many programs can be ran at same time • Became accessible to a mass audience • Even Smaller • Even Cheaper Brian Ly

  8. Carry out instructions in billionths of a second. • Size of machine dropped to the size of small file cabinets. Brian Ly

  9. Fourth Generation1971 - Present • Microprocessor • Thousands of integrated circuits were rebuilt onto a single silicon chip. • Contains a CPU • Controls the logic of almost all digital devices • Three basic characteristics differentiate microprocessors: • Instruction Set • Bandwidth • Clock Speed • Higher the values, the more powerful the CPU is Brian Ly

  10. First generation computers can now be fit in the palm of the hand. • Intel 4004chip located all the components of the computer. • CPU is the brain of the computer • Most calculation takes place • Most important element of a computer system • Large machines require CPUs with one or more printed circuit boards • PCs and Small workstations housed by a single chip, the microprocessor. Brian Ly

  11. Two typical components of a CPU: • ALU • Arithmetic Logic Unit • Control Unit • 1981 - IBM introduced its first computer for the home user. • 1984 – Apple introduced the Macintosh. • Microprocessors moved out of the realm of desktop computers. Brian Ly

  12. Fifth GenerationPresent - Beyond • Artificial Intelligence • Still in development • Branch of computer science concerned with making computer behave like humans • Includes: • Games Playing • Expert Systems • Natural Language • Neural Networks • Robotics Brian Ly

  13. No Computers exhibit full artificial intelligence • Greatest advances • In the fields of games playing • Chess programs • Capable of beating humans • IBM super computer, “Deep Blue” • Robots widely used in assembly plants

  21. What was UNIVAC? • UNIVAC is the first commercial computer produced in the United States • The Acronym stands for “Universal Automatic Computer” which was chosen by John Mauchly in 1947. • Designed by Dr. Presper Eckert and Dr. John Mauchly Jeanette Gerardo

  22. Cont. • Its design and contract was not finalized until 1948 • Costs for this project were erroneous and almost drove its inventors to bankruptcy • The project was not accepted by the Census Bureau until March 31, 1951 • Costs to finally construct the UNIVAC were close to a million dollars Jeanette Gerardo

  23. Components Of UNIVAC • The infamous UNIVAC was 25feet by 50 feet in length, and was composed of about 5600 tubes, 18000 crystal diodes and 300 relays. • Its internal capacity was of about 1000 words to 12000 characters. Jeanette Gerardo

  24. Components Of UNIVAC • Its processing speed was .525 milliseconds for arithmetic functions, 2.15 milliseconds for multiplication and 3.9 Milliseconds for division. • It was unique from any other invention since it provided the separation of complex problems of input and the output from the actual computation Jeanette Gerardo

  25. UNIVAC Jeanette Gerardo

  26. -In 1952, it successfully predicted the outcome of the 1952 presidential election during a televised news broadcast. -UNIVAC was soon used to compute major company’s payrolls, sales records, sales performance, etc. -The largest amount of UNIVAC’s to be delivered took place in 1958 Jeanette Gerardo

  27. Additions to UNIVAC • The first practical compiler that consisted of a group error-free programs placed on tapes that were in turn assigned to call numbers. • Automatic programming which enabled computers to write their own programs from using key instructions. • Data processing: (Flow-matic) was the first computer language consisted of 500 typical programs and identified 30 verbs that shared commonalities amongst all. Jeanette Gerardo

Died November 27, 1852. • Her Father was the famous Romantic poet Lord Byron. • Her mother made sure she was tutored in mathematics and music because she did not want her daughter to be a poet like her father. • She was later influenced by Charles Babbage who also become a lifelong friend. Rosa Morales

  41. Ada Lovelace and Charles Babbage • She met Babbage at age 17 • Babbage was a Mathematics Professor in Cambridge • He came up with the idea of a analytical engine • Ada helped translate transcripts that informed on analytical engine. • The Analytical Engine was steam powered general purpose computing machine Rosa Morales

  42. Ada Continue • Analytical Engine • An analytical engine “basic function was an empty box. It didn’t actually do anything itself, but merely executed whatever ‘program’ was applied by its operator.” • The transcripts Ada translated led to “the acceptance of the first computer program.” • She introduced computer programming but during her lifetime it was never tested. Rosa Morales
