- 1. A Journey Through the Evolution of Computers We'll embark on a fascinating journey through the history of computers, exploring key milestones, influential figures, and the profound impact these inventions have had on our world. by Tanishq Yadav
- 2. Early Calculating Devices The Abacus One of the earliest calculating devices, used in ancient Mesopotamia and China, allowed for basic arithmetic operations. The Slide Rule Developed in the 17th century, the slide rule enabled more complex calculations using logarithmic scales.
- 3. The Birth of the Modern Computer 1 Charles Babbage Conceptualized the Analytical Engine, a mechanical general- purpose computer, in the 19th century. 2 Ada Lovelace Considered the first computer programmer, she wrote algorithms for Babbage's machine. 3 Herman Hollerith Developed the first electromechanical tabulating machine for the 1890 U.S. Census.
- 4. The ENIAC and the Turing Machine ENIAC The first electronic general- purpose computer, completed in 1946, was used for ballistics calculations during World War II. Turing Machine A theoretical model of computation, proposed by Alan Turing, laid the foundation for modern computer science.
- 5. The Rise of Personal Computers Apple II One of the first commercially successful personal computers, released in 1977, popularized home computing. IBM PC The IBM Personal Computer, released in 1981, established an industry standard and became the dominant platform.
- 6. The Evolution of Software and Programming 1 Assembly Language Low-level programming language that directly interacts with hardware. 2 High-Level Languages Languages like Fortran, COBOL, and BASIC made programming more accessible. 3 Object-Oriented Programming Introduced concepts like classes and objects, leading to more complex and modular software.
- 7. The Internet and the Digital Age 1 ARPANET The precursor to the internet, developed in the 1960s by the U.S. Department of Defense. 2 World Wide Web The World Wide Web, invented by Tim Berners-Lee in the late 1980s, revolutionized information sharing. 3 Mobile Revolution Smartphones and mobile devices have transformed the way we access information and communicate.
