History of Computing

Study Notes

Early Computing

Charles Babbage, often referred to as the "Father of the Computer," conceptualized the "Difference Engine" in the early 19th century for navigational calculations.
Babbage's more general "Analytical Engine" was developed in 1833, but funding constraints prevented its completion during his lifetime.
His son, Henry, completed a simpler version of the "Difference Engine" in 1888, which was publicly demonstrated in 1906.

Early 20th-Century Computing

The first electromechanical digital computer, the Z2, was created by Konrad Zuse in 1939 and used electric switches and relays for calculations.
Zuse also developed the first fully automatic computer, the Z3, in 1941.
Colossus, a series of programmable electronic digital computers, was developed between 1943 and 1945, primarily used for breaking German Enigma codes during World War II.

Modern Computing Era

Alan Turing's 1936 paper "On Computable Numbers" laid the groundwork for modern computers by outlining the concept of stored program instructions.
The Manchester Mark 1, developed at the Victoria University of Manchester in 1948, was one of the first programmable computers.
The Ferranti Mark 1, also known as the Manchester Electronic Computer, was the world's first commercially available general-purpose computer, released in 1951.
The Leo I, developed by the Lyons Tea Corporation in 1951, was the first computer used for commercial business applications.

Milestones in Communication Technology

Morse code, invented by Samuel Morse in 1835, revolutionized long-distance communication.
The Electric Telegraph, jointly invented by Charles Wheatstone and Samuel Morse in 1838, facilitated instant communication over vast distances.
Radio waves were produced by Heinrich Hertz in 1888, laying the foundation for radio communication.
Nikola Tesla pioneered wireless communication in 1893, followed by Guglielmo Marconi's invention of radio signals in 1895.
The invention of the microphone by Emile Berliner in 1877 allowed for sound amplification.

Other Important Milestones

The invention of the typewriter by Charles Thurber in 1843 enabled mass production of printed documents.
The invention of the photocopier by Xerox in 1959 allowed for fast and easy document duplication.
The first computer mouse was invented by Douglas Engelbart in 1963, revolutionizing user interaction with computers.
The invention of e-mail by Ray Tomlinson in 1971 enabled electronic communication between computer users.
The Intel 4004, the first commercially available microprocessor, was invented in 1971, which opened up a new era of computing devices.

Key Developments in Computer Components

The hard disk drive was invented by IBM in 1956, providing large storage capacity for computers.
The development of the silicon chip, the first integrated circuit, by Jack Kilby and Robert Noyce in 1958 led to smaller and more powerful computers.
Liquid crystal displays (LCDs) were invented by James Fergason in 1971, leading to thinner and more energy-efficient displays.
The floopy disk was invented by David Noble in 1971, providing a convenient means for storing and transferring data.
