Study Notes
Introduction to Computing
- Computers are ubiquitous, found in schools, workplaces, homes, and businesses.
- Early mechanical calculators included the Pascaline, invented by Blaise Pascal in 1642, facilitating addition and subtraction faster than the abacus.
- Gottfried Wilhelm Leibniz developed the Leibniz Wheel in 1685, enhancing the Pascaline with automatic multiplication and division through a stepped drum mechanism.
Significant Inventions
- The Jacquard Loom, created by Joseph Marie Jacquard in 1804, automated cotton weaving using punched cards, a precursor to modern programming techniques.
- The abacus, dating back to around 3000 BC, was the earliest mechanical device for calculations, utilizing beads on rods, and remains in use today for teaching basic arithmetic.
Evolution of Computers
- The evolution of computing transitions from the Mechanical Era (1450-1840) to the Electronic Era (1940-present).
First Generation (1946-1959)
- Utilized vacuum tubes for memory and Central Processing Unit (CPU).
- Input and output methods included punched cards, paper tape, and magnetic tape.
Second Generation (1959-1965)
- Introduced transistors, which were cheaper, consumed less power, and were more compact than vacuum tubes.
Third Generation (1965-1971)
- Integrated Circuits (ICs) were developed by Jack St. Clair Kilby, revolutionizing computer design and efficiency.
Fourth Generation (1971-1980)
- Very Large-Scale Integrated Circuits (VLSICs) made computers more powerful, reliable, compact, and affordable.
Networking and Cloud Computing
- Computer networks consist of linked computers that share data and resources.
- Cloud computing provides access to information, applications, communication, and storage over the internet.
