Study Notes
Charles Babbage
- Proposed the difference engine for solving differential equations, which utilized steam power and featured automatic calculations.
- Developed the analytical engine, recognized as the first general-purpose computer, after spending a decade on the difference engine.
- Lady Augusta Ada King contributed to the analytical engine by creating its instruction routines, making her the first female computer programmer.
Herman Hollerith
- In 1889, invented a data storage method using punched cards, which he inputted into a machine to mechanically compile results.
- The use of punched cards improved computational speed and accuracy, reducing the likelihood of errors.
John V. Atanasoff & Clifford Berry
- Designed and constructed the Atanasoff-Berry Computer (ABC), regarded as the first electronic digital computer.
- The ABC laid the groundwork for subsequent developments in electronic calculators and modern computing technology.
Charles Babbage and Lady Augusta Ada King
- Charles Babbage, a professor, proposed the difference engine to perform differential equations using steam power.
- The difference engine could execute calculations, store programs, and automatically print results.
- After a decade on the difference engine, Babbage was inspired to create the analytical engine, the first general-purpose computer.
- Lady Augusta Ada King, Babbage's assistant, developed the instruction routines for the analytical engine, earning the title of the first female computer programmer.
Herman Hollerith
- In 1889, inventor Herman Hollerith introduced punched cards to store data.
- Hollerith's machine mechanically compiled results from the punched cards, which allowed for quick data processing.
- Punched cards also served as a reliable storage method and reduced computation errors.
William Hollerith and Electronic Computers
- John V. Atanasoff and Clifford Berry designed the first electronic digital computer called the Atanasoff-Berry Computer (ABC).
- The ABC laid the groundwork for future advancements in electronic calculators and computing technology.
