The History of Computers
Summary
The video traces the history of computers from 300 BCE to the modern era, exploring key innovations and inventors along the way. It covers early calculating machines like Wilhelm Schickard's calculating clock and Blaise Pascal's Pascaline, as well as the development of punch cards by Herman Hollerith, leading to the founding of IBM. The video also touches on important milestones like the introduction of ENIAC, the first all-electric digital computer, and the invention of the microprocessor by Intel in 1971, shaping the way for modern computing technology.
Introduction to Computers
The history of computers starting from 300 BCE when electronic computers were first named to perform work, the role of human computers in performing calculations, the development of the abacus, and the early gear-driven calculating machines by various inventors.
Wilhelm Schickard and Blaise Pascal
Wilhelm Schickard's calculating clock and Blaise Pascal's Pascaline, which were early gear-driven calculating machines designed for mathematical computations, along with Joseph Marie Jacquard's power loom invention in 1801.
Charles Babbage and Herman Hollerith
The proposal of the steam-driven calculating machine by Charles Babbage, the difficulties in constructing Babbage's Difference Engine, and Herman Hollerith's use of punch cards for the 1890 census and the founding of his company later known as IBM.
Early Mechanical Calculators
The development of mechanical calculators by IBM, such as the Harvard Mark 1 in 1944, Grace Hopper's debugging of the Mark 1, and the role of Colossus in breaking cryptographic codes during World War II.
ENIAC and UNIVAC
The introduction of ENIAC as one of the first all-electric digital computers, its massive size, usage of vacuum tubes, and the subsequent development of UNIVAC, the first commercial computer to use magnetic tape.
Microsoft and Microprocessors
The partnership between IBM and Microsoft, the rise of Microsoft as a dominant player, the invention of the microprocessor at Intel in 1971, and the development of the first microprocessor, the Intel 4004.
