History of Computers Timeline Presented by: Amanda and Andy
Earliest forms 300 B.C.: The abacus is believed to have been the earliest known calculating device. AD 1625: The Slide rule was able to perform mathematical calculations. AD 1642: The Pascaline was used by; rotating the gears, the user could perform basic mathematical operations.
The 1800’s 1801: Joseph-Marie Jacquard invents an automatic weaving loom that reads instructions from punched cards. 1830: The Analytical Engine, is considered to be a computer in the modern sense of the word. (created by; Charles Babbage) 1833: Augusta Ada Lovelace is generally recognized as the world’s first computer programmer. 1890: The Tabulating machine which could automatically read census information punched onto cards.
The 1900’s 1941: The Z3, was the world’s first fully functional, programmed- controlled computer. 1942: Atanasoff-Berry Computer was not designed for general- purpose processing. 1943: The Colossus, a computer used by the British to crack German codes during World War II. 1944: The Mark I, which data was stored electronically inside the device with the use of electromagnetic rays. 1945: Dr. John von Neumann describes the stored program concepts. (written)
Continued.. 1946: The Electronic Numerical Integrator and Calculator (ENIAC), which was used by the U.S government for a variety of computing tasks. 1947: The Transistor would lead to the development of smaller and faster computers. 1951: The Universal Automatic Computer is the first commercial computer produced in the United States. 1953: IBM introduced its new model 650 computer.
Continued…. 1956: IBM’s 305 RAMAC, was the first computer to use magnetic disk storage 1957: John Backus at IBM introduces an efficient and easy-to-use programming language, called FORTRAN (Formula Translation) 1957: The Soviet Union launches Sputnik I, the first orbiting satellite. 1958: Jack Kilby invents the integrated circuit. (later would be used for larger storage capacity)
The 1960’s 1960: Grace Hopper, helped develop Common Business-Oriented Language. 1965: John Kemeny helped develop the basic programming language. 1969: The United States Defense Advanced Research Agency (ARPA) establishes ARPLANET, wide area linking colleges. 1970: The powerful UNLX operating system is developed at Bell Laboratories. 1970: A new generation of computers emerged.
1970’s part 1 1971: Ted Hoff develops the Intel 4004 microprocessor. 1971: A team of IBM engineers introduced the first 8-inch memory disk. 1971: Cray research finder, introduces the Cray-1, worlds first super computer. (can process complex applications)
1970’s part 2 1972: Hewlett-Packard introduces a series of scientific pocket calculators. 1972: The C programming language is developed at Bell Laboratories. 1973: Xerox’s Palo Alto research center develops the Alto computer.
Continued… 1975: Dr. Robert Metcalf develops Ethernet. (The first local network) 1976-1977: (1976) Steve Jobs and Steve Wozniak, built the first apple computer., the following year Apple introduced the Apple II personal computer, capable of displaying texts and graphics. 1978: VisiCalc, for the Apple II computer, Daniel Bricklin and Bob Frankston Developed this.
1980’s part 1 1980: MSDOS was developed, bill gates accepted the offer IBM made. 1980: Sony Electronics introduces the 3.5-inch floppy disk and disk drive. 1981: IBM introduces the IBM PC 1981: The first computer virus, called ELK Cloner, this affected the Apple II spreadsheet.
