Study Notes
Early Concepts and Mechanical Calculators
- Ancient Tools: The abacus served as one of the earliest computation tools, utilized across ancient cultures like Mesopotamia and China.
- 17th Century Innovations: Blaise Pascal invented the Pascaline, a mechanical calculator for addition and subtraction; Gottfried Wilhelm Leibniz later created the Step Reckoner for multiplication and division.
The 19th Century: Theoretical Foundations
- Charles Babbage: Designed the Analytical Engine in the 1830s, which included components like an arithmetic logic unit, memory, and conditional branching, resembling modern computer architecture, though never completed.
- Ada Lovelace: Collaborated with Babbage, recognized as the first computer programmer for writing an algorithm intended for machine processing.
Early 20th Century: Electronic and Mechanical Advances
- Electromechanical Computers: Konrad Zuse developed the Z3 in the 1920s-1930s, a programmable computer using relays.
-
1940s Electronic Expansion:
- ENIAC: Completed in 1945, considered one of the first general-purpose electronic digital computers, capable of various calculations.
- UNIVAC I: Launched in 1951 as the first commercially available computer, primarily for business data processing.
The 1950s and 1960s: The Mainframe Era
- Mainframes: Dominated business and scientific calculations with powerful models like the IBM 701 and IBM 1401, catering to large-scale computing tasks.
- Transistor Revolution: Developed in 1947 by Bell Labs, transistors replaced vacuum tubes, making computers smaller, more reliable, and energy-efficient.
The 1970s and 1980s: Personal Computers and Microprocessors
- Introduction of Microprocessors: The 1970s marked the emergence of microprocessors, integral to modern computing; Intel’s 4004 debuted in 1971 as one of the first.
-
Personal Computer Revolution:
- Apple II: Released in 1977, recognized as one of the first successful mass-produced microcomputers.
- IBM PC: Introduced in 1981, it established the personal computer standard, promoting widespread adoption in homes and businesses.
