Transcript

  • 1. The History Of The Computer By: Sara Poirier
  • 2. First Programmable Computer
    • The Z1 was created in Germany by Korad Zuse in 1936.
  • 3. The Z1
    • The Z1 had a 64-word memory and a clock speed of 1Hz. To program the Z1 required that the user insert punch tape into a punch tape reader. All output was generated with punch tape.
  • 4. The First Digital Computer
    • The ABC (short for Atanasoff-Berry Computer) started being developed by Professor John Vincent Atanasoff and Graduate Student Cliff Berry in 1937 and continued to be developed until 1942.
  • 5. Atanasoff-Berry Computer (ABC)
    • The ABC was the first electronic digital computing device. Conceived in 1937, the machine was not programmable, but designed only to solve systems of linear equations.
  • 6. The First Computer With RAM
    • MIT introduces the Whirlwind machine March 8, 1955, a revolutionary computer that was the first digital computer with magnetic core RAM and real-time graphics.
  • 7. The First Transistor Computer
    • The TX-O (Transistorized Experimental computer) and first transistorized computer is demonstrated at the Massachusetts Institute of Technology in 1956.
  • 8. The First Stored Program Computer
    • The early British computer known as the EDSAC is considered to be the first stored program electronic computer.
  • 9. The EDSAC
    • The computer performed its first calculation on May 6, 1949 and was the computer that ran the first graphical computer game.
  • 10. The First Minicomputer
    • In 1960 Digital Equipment Corporation (DEC) released its first of many PDP computers the PDP-1.
  • 11. PDP-1
    • PDP (Programmable Data Processor) was a series of computers developed by digial. The PDP-1 was developed in 1960, had five-megacycle circuits, a magnetic core memory, and fully parallel processing with a computation rate of 100,000 additions per second.
  • 12. The First Personal Computer
    • In 1975 Ed Roberts coined the term personal computer when he introduced the Altair 8800.
  • 13. The Micral
    • The Micral is considered the be the first commercial non-assembly computer. The computer used the Intel 8008 processor and sold for $1,750 in 1973.
  • 14. The First Workstation
    • Although never sold the first workstation is considered to be the Xerox Alto, introduced in 1974.
  • 15. The First Laptop
    • The first portable computer or laptop is considered to be the Osborne I, which was released on April 1981.
  • 16. Osborne 1
    • The Osborne I was developed by Adam Osborne and weighed 24 pounds, had a 5-inch display, 64 KB of memory, two 5 1/4" floppy drives, and a modem.
  • 17. The First PC Computer
    • On April 7, 1953 IBM publicly introduced the 701, its first electric computer and first mass produced computer.
  • 18. The 701
    • First introduced on April 7, 1953, the 701 was IBM's first electric computer and the first mass produced computer. The machine has 256 40-bit words of main memory and can perform 2,200 multiplications per second.
  • 19. The First PC Clone
    • The first PC clone was developed by Compaq, the "Compaq Portable" was release in March 1983 and was 100% compatible with IBM computers and software that ran on IBM computers.
  • 20. The First Apple Computer
    • Steve Wozniak designed the first Apple known as the Apple I computer in 1976.
  • 21. The Apple 1
    • The Apple I ( Apple 1 ) is the first Apple computer and originally sold for $666.66. The computer kit was developed by Steve Wozniak in 1976 and contained a 6502 8-bit processor and 4 kb of memory, which was expandable to 8 or 48 kb using expansion cards.
