Study Notes
Early Computing Developments
- Significant advancements in computing began in 1939 at Harvard University with IBM’s support for a modernized Analytical Engine project.
- First electromechanical computer was recognized in 1944, capable of automatic scientific computations using punched tapes.
Atanasoff-Berry Computer (ABC)
- Invented by Professor John Atanasoff and student Clifford Berry from 1939-1942 at Iowa State University.
- Notable as the first electronic digital computing device weighing 700 lbs (320 kg).
- Featured a memory capacity of 3000 bits and utilized over 300 vacuum tubes at a frequency of 60 Hz for processing.
ENIAC
- Stands for Electronic Numerical Integrator and Computer, designed by John W. Mauchly and J. Presper Eckert during World War II.
- Recognized as the first electronic digital computer; its architecture laid groundwork for future computing.
- Mauchly and Eckert formed a company post-war, creating the Universal Automatic Computer (UNIVAC), the first commercial computer sold to the US Census Bureau in 1951.
EDVAC
- The Electronic Discrete Variable Automatic Computer is hailed as the first stored-program computer.
- Idea introduced by Hungarian-American mathematician John von Neumann in 1945, promoting program storage in memory similar to data storage.
- This concept became the foundation for modern computer designs.
Osborne 1
- Released by Osborne Computer Company in 1981, this was the first portable computer, marking a significant leap in personal computing.
Electric Controls Company
- Founded in 1949 by John Presper Eckert and John Mauchly, recognized as the first computer company.
Personal Computers (1970-1979)
- Development of personal computers commenced in the 1970s, spurred by the introduction of the Altair 8800, Scelbi-8H, and Apple computers.
- Bill Gates and Paul Allen developed BASIC programming for Microsoft, while Steve Jobs and Steve Wozniak founded Apple Computer in 1972.
- By 1977, popular models included Apple II, Atari, Commodore, and TRS-80, widely used in homes, schools, and businesses.
Business Computers (1980-1987)
- IBM expanded into the personal computer market, focusing on business applications.
- Manufacturers enhanced digital microcomputers tailored for business needs and graphical environments.
Modern Computers (1988-Present)
- Transitioned to smaller computers with greater storage capabilities.
- Innovations included laptops, computer notebooks, programmable calculators, modems, email, networking, and multimedia technologies.
Notable Early Inventions
- Jacquard Loom: Invented by Joseph-Marie Jacquard in 1801; automated loom operated via punched cards.
- Arithmometer: The first commercially successful calculating machine created by Thomas de Colmar in 1820.
- Difference Engine: Charles Babbage’s 1822 invention designed for automatic polynomial calculations.
- Analytical Engine: Proposed by Babbage in 1834, considered the first mechanical computer with general-purpose capabilities.
- Augusta Ada Byron: Acknowledged as the first computer programmer for writing algorithms for the Analytical Engine in 1840.
- Scheutzian Calculation Engine: An 1843 creation by Per Georg Scheutz based on the Difference Engine, recognized as the first printing calculator.
- Tabulating Machine: Invented in 1890 by Hermen Hollerith, utilized punch cards to automate data processing for the US Census Bureau and led to the formation of IBM.
- Mark 1: Developed by Howard H. Aiken, further contributing to early computing technology.
