When was the first computer invented?
First in computer Invention, there is no easy answer to this question due to the different classifications of computers. The first mechanical computer, built by Charles Babbage in 1822, had nothing to do with today’s computers. Therefore, this page first provides a list of all the computers, starting with the comparison engine and ending with the computers you are using today.
When was the word computer first used?
The term “computer” was first used in 1613 in Richard Braithwaite’s book The Young Men’s Glennings. The definition of computer was the same until the end of the 19th century. when the Industrial Revolution created mechanical devices whose main purpose was to compute.
The first idea of a mechanical computer or an automatic calculator
In 1822, Charles Babbage designed and introduced the Difference Engine, which would be the first automatic calculator capable of measuring almost polynomials. The comparison engine was able to calculate several sets of numbers and output the results on paper.
Unfortunately, due to lack of funds, Babbage could not complete the fully functional version of this machine. In June 1991, the London Science Museum exhibited the Difference Engine No. 2 to commemorate the bicentennial of Babbage, and later completed the printing in 2000.
The first machine to record and store information
In 1890, Herman Hollerith developed a method for machines for recording and storing punchcard information for the U.S. Census. Halerith’s machines were about 10 times faster than manual spreadsheets and saved the company millions of dollars. Bureau of Statistics. Holreith discovered a company now known as IBM.
The first general purpose computer
In 1837, Charles Babbage introduced the first general mechanical computer, the analytical engine. Analysis engines include ALU (unit of arithmetic reasoning), basic flow control, punched card (inspired by Jacquard Loom), and on-board memory. This is the first universal computing concept that can be use for many things, not just accurate calculations. In 1910, Henry Babbage, the youngest son of Charles Babbage, was able to complete parts of this machine and perform basic calculations.
The first programmable computer
The Z1 was make by German Conrad Zeus in his parents’ living room between 1936 and 1938. It is consider to be the first electromechanical binary programmable computer and the first working modern computer.
The first idea of modern computer.
The Turing machine was first proposed by Alan Turing in 1936 and became the basis of computer science and computer theory. An instrument is a device that prints symbols on a sheet of paper in a way that mimics a person following a series of logical instructions. Without these building blocks, we would not have the computers we have today.
The first electrically programmable computer
The Colossus was the first electrically programmable computer, made by Tommy Flower, and first appeared in December 1943. Colossus was create to help British decryptors read encrypt German messages.
The first digital computer
In 1937, Professor John Vincent Atanasoff, a graduate student, and ABC, Atanasoff-Bary began developing computers. Iowa State College (now Iowa State University) continued its development until 1942.
The ABC was an electric computer that used more than 300 vacuum tubes for numerical calculations, including binary math and Boolean logic, and had a (non-programmable) processor. October 19, 1973, U.S. Federal Judge Earl R. Larson signed his verdict. The ENIAC patents of Presper Eckert and John Mauchley were invalid. In conclusion, Larsen named Atanasov the only inventor.
The first recorded program is a computer
The first computer to be electronically store and operated was the SSEM (Small-Scale Experimental Machine), also known as “Baby” or “Manchester Baby”, in 1948. It was design by Frederick Williams and his students. Assisted by Jeff Tuttle of Tom Kilburn at the University of Manchester, England. Kilburn was the first to write an electronically saved program that finds the most precise element of an integer using repetitive subtraction instead of division. The Kilburn Program was launch on 21 June 1948.
The first computer company
The first computer company was the Electronic Control Company and in 1949 J. Presper Eckert and John Mouchley, the same men who helped build the ENIAC computer. The company was later rename EMCC or Eckert-Mauchly Computer Corporation, and many mainframe computers called UNIVACs was sell by them.
The first computer with a program stored in memory
The UNIVAC 1101 or ERA 1101 was first give to the United States government in 1950 and is considere the first computer capable of storing and running programs from memory.
The first computer with RAM
MIT unveiled the rotating machine on March 8, 1955, a revolutionary system that was the first digital computer with magnetic-core RAM and real-time graphics.
The first transistor computer
TX-0 (Transistorized Experimental Computer) The first transistor computer was introduce in 1956 at the Massachusetts Institute of Technology.
The first microcomputer
In 1960, Digital Equipment Corporation introduced the PDP-1, the first of several PDP computers.
First job based Computer
Although never sold, the first workstation is believe to be the Xerox Alto, which was launched in 1974. Computers were revolutionary for their time and included fully functional computers, displays and mice. Computers, like many of today’s computers, use Windows, menus, and icons as interfaces to their operating systems.
Intel introduced the first microprocessor, the Intel 4004, on November 15, 1971.
The microcomputer was create in 1973 by French-Vietnamese engineers André Trung Trong and François Gornel. Considered the first microcomputer, it uses the Intel 8008 processor and is the first non-assembly commercial system. They were originally sell for 1,750.
The first personal computer (PC)
In 1975, Ed Roberts coined the term “personal computer”, introducing the Altair 8800. However, the first personal computer is consider by many to be the Canback-1, which first launched in 1971 for $750. The computer depends on many switches. Data input and data output on and off with multiple lights.
First laptop or notebook
The IBM 5100 was the first portable computer-system to be release in September 1975. The computer weighed 55 pounds and had a 5-inch CRT display, tape drive, Palm 1.9 MHz processor, and 64 KB of RAM. Scientific American advertises the November 1975 issue of the IBM 5100.
Apple’s first computer
The Apple I (Apple 1) was Apple’s first computer, originally selling for $666.66. Created by Steve Wozniak in 1976, the system kit contain an 8-bit 6502 processor and 4 KB of memory, which could be expand to 8 or 48 KB via an expansion card. Even though Apple-I comes with an entire circuit board . The kit still needs a power supply, display, keyboard, and attachments to function. Below is a photo of the Apple I in an Apple ad.
First multimedia System
In 1992, Tandy Radio Shack released the M2500 XL/2 and M4020 SX, the first computers to support the MPC standards.
