What is the history of computer?

history of computer

The history of computers is more than 200 years old. In this article we have told a brief history of computers. First theorized by mathematicians and entrepreneurs, mechanical counting machines were designed and built during the 19th century to solve increasingly complex number-crunching challenges. The history of computers began with primitive designs in the early 19th century and went on to change the world during the 20th century.

Nowadays, computers are almost indistinguishable from 19th-century designs, such as Charles Babbage’s Analytical Engine – or even the massive 20th-century computers that occupied entire rooms, such as electronic numerical integrators and calculators.

History of computer in ancient romans to 1662:

Ancient Roman:

The ancient Romans developed an Abacus, the first “machine” for calculating. While it predates the Chinese abacus we do not know if it was the ancestor of that Abacus. Counters in the lower groove are 1 x 10n, those in the upper groove are 5 x 10n.

Blaise Pascal(1623-1662):

Blaise Pascal, a French mathematical genius, at the age of 19 invented a machine, which he called the Pascaline that could do addition and subtraction to help his father, who was also a mathematician. Pascal’s machine consisted of a series of gears with 10 teeth each, representing the numbers 0 to 9. As each gear made one turn it would trip the next gear up to make 1/10 of a revolution. This principle remained the foundation of all mechanical adding machines for centuries after his death. The Pascal programming language was named in his honor.

History of computer in 19th century:

1801:

In France, weaver and merchant Joseph Marie Jacquard creates a loom that uses wooden punch cards to automate the design of woven fabrics. Early computers would use similar punch cards.

1822:

English mathematician Charles Babbage invents a steam-driven calculating machine that was able to compute tables of numbers.

1890:

Inventor Herman Hollerith designs the punch card system to calculate the 1880 U.S. census. It took him three years to create, and it saved the government $5 million. He would eventually go on to establish a company that would become IBM.

History of computer in early 20th century:

1931:

Vannevar Bush invents and builds the Differential Analyzer, the first large-scale automatic general-purpose mechanical analog computer, according to Stanford University.

1936:

British scientist and mathematician Alan Turing developed an idea for a universal machine, which he would call the Turing machine, that would be able to compute anything that is computable. The concept of modern computers was based on his idea.

1937:

At Iowa State University , J.V. Atanasoff, attempts to build the first computer without cams, belts, gears, or shafts.

1939:

Bill Hewlett and David Packard found Hewlett-Packard in a garage in Palo Alto, California. Their first project, the HP 200A Audio Oscillator, would rapidly become a popular piece of test equipment for engineers.

1941:

At Iowa State University J.V. Atanasoff and graduate student Clifford Berry design a computer that can solve 29 equations simultaneously. This is the first time a computer is able to house data within its own memory.
That same year, German engineer Konrad Zuse creates the Z3 computer, which used 2,300 relays, performed floating-point binary arithmetic, and had a 22-bit word length.

1943:

At the University of Pennsylvania, build an Electronic Numerical Integrator and Calculator (ENIAC). This is considered to be the grandfather of digital computers, as it is made up of 18,000 vacuum tubes and fills up a 20-foot by 40-foot room.

1944:

British engineer Tommy Flowers designed the Colossus, which was created to break the complex code used by the Nazis in World War II. A total of ten were delivered, each using roughly 2,500 vacuum tubes. These machines would reduce the time it took to break their code from weeks to hours, leading historians to believe they greatly shortened the war by being able to understand the intentions and beliefs of the Nazis.

1945:

Mathematician John von Neumann writes The First Draft of a Report on the EDVAC. This paper broke down the architecture of a stored-program computer.

1946:

Mauchly and Eckert left the University of Pennsylvania and obtained funding from the Census Bureau to build the UNIVAC. This would become the first commercial computer for business and government use.

1947:

Walter Brattain, William Shockley, and John Bradeen of Bell Laboratories invented the transistor, which allowed them to discover a way to make an electric switch using solid materials, not vacuums.

1948:

Geoff Toothill, Frederick Williams and Tom Kilburn built to test new memory technology, which became the first high-speed electronic random access memory for computers. The became the first program to run on a digital, electronic, stored-program computer.

1950:

Built in Washington, DC, the Standards Eastern Automatic Computer (SEAC) was created, becoming the first stored program computer completed in the United States. It was a test-bed for evaluating components and systems, in addition to setting computer standards.

History of computer in late 20th century:

1953:

Computer scientist Grace Hopper develops the first computer language, which is eventually known as COBOL, that allowed a computer user to use English-like words instead of numbers to give the computer instructions. In 1997, a study showed that over 200 billion lines of COBOL code were still in existence.

1954:

The FORTRAN programming language is developed by John Backus and a team of programmers at IBM.

Atlas computer makes its debut, thanks to Manchester University, Ferranti Computers, and Plessy. At the time, it was the fastest computer in the world and introduced the idea of “virtual memory”.

1964:

Douglas Engelbart introduces a prototype for the modern computer that includes a mouse and a graphical user interface (GUI). This begins the evolution from computers being exclusively for scientists and mathematicians to being accessible to the general public.

Additionally, IBM introduced SABRE, their reservation system with American Airlines. It program officially launched four years later, and now the company owns Travelocity. It used telephone lines to link 2,000 terminals in 65 cities, delivering data on any flight in under three seconds.

1968:

A Space Odyssey hits theaters. This cult-classic tells the story of the HAL 9000 computer, as it malfunctions during a spaceship’s trip to Jupiter to investigate a mysterious signal. The HAL 9000, which controlled all the ship, went rogue, killed the crew, and had to be shut down by the only surviving crew member. The film depicted computer demonstrated voice and visual recognition, human-computer interaction, speed synthesis, and other advanced technologies.

Also, the programming language C++ is published and is said to make programming “more enjoyable” for the serious programmer.

1986:

Originally called the Special Effects Computer Group, Pixar is created at Lucasfilm. It worked to create computer-animated portions of popular films, like Star Trek II: The Wrath of Khan. Steve Jobs purchased Pixar in 1986 for $10 million, renaming it Pixar. It was bought by Disney in 2006.
