The Difference Engine
The first computer invented was in 1822, and the person who made the computer his name was Charles Baggage and the computer was called the difference Engine and the purpose of the difference Engine was computing several sets of numbers and making hard copies of those sets of numbers -
The Analytical Engine
In 1837, Charles Baggage Proposed the Fist general Mechanical computer, and the purpose of this Mechanical computer was to Punch cards, and integrate memory -
Analytical Engine partly completed
When Charles baggage died, his son Henry Baggage was able to complete a portion of the Analythical Engine and he was able to perform basic calculations -
First Programmable Computer
Konrad Zuse created the Z1 in his parent's living room, and the Z1 was considered to be the first electro-mechanical binary programmable computer, the first really functional modern computer -
The turing Machine
The Turing machine was first proposed by Alan Turing in 1936 and became the foundation for theories about computing and computers. The machine was a device that printed symbols on paper tape in a manner that emulated a person following a series of logical instructions. Without these fundamentals, we wouldn't have the computers we use today. -
The first electric programmable computer
The Colossus was the first electric programmable computer, developed by Tommy Flowers, and first demonstrated in December 1943. The Colossus was created to help the British code breakers read encrypted German messages. -
The first digital computer
The ENIAC was invented by J. Presper Eckert and John Mauchly at the University of Pennsylvania and began construction in 1943 and was not completed until 1946. It occupied about 1,800 square feet and used about 18,000 vacuum tubes, weighing almost 50 tons. Although the Judge ruled that the ABC computer was the first digital computer, many still consider the ENIAC to be the first digital computer because it was fully functional. -
The first computer company
The first computer company was the Electronic Controls Company and was founded in 1949 by J. Presper Eckert and John Mauchly, the same individuals who helped create the ENIAC computer. The company was later renamed to EMCC or Eckert-Mauchly Computer Corporation and released a series of mainframe computers under the UNIVAC name. -
The first stored program computer
The early British computer known as the EDSAC is considered to be the first stored program electronic computer. The computer performed its first calculation on May 6, 1949 and was the computer that ran the first graphical computer game, nicknamed "Baby". -
First stored program computer
First delivered to the United States government in 1950, the UNIVAC 1101 or ERA 1101 is considered to be the first computer that was capable of storing and running a program from memory. -
First commercial computer
In 1942, Konrad Zuse begin working on the Z4 that later became the first commercial computer. The computer was sold to Eduard Stiefel, a mathematician of the Swiss Federal Institute of Technology Zurich on July 12, 1950. -
IBM's first computer
On April 7, 1953 IBM publicly introduced the 701; its first commercial scientific computer. -
The first computer with RAM
MIT introduces the Whirlwind machine on March 8, 1955, a revolutionary computer that was the first digital computer with magnetic core RAM and real-time graphics. -
The first transistor computer
The TX-O (Transistorized Experimental computer) is the first transistorized computer to be demonstrated at the Massachusetts Institute of Technology in 1956. -
The first minicomputer
In 1960, Digital Equipment Corporation released its first of many PDP computers, the PDP-1. -
The first desktop and mass-market computer
In 1964, the first desktop computer, the Programma 101, was unveiled to the public at the New York World's Fair. It was invented by Pier Giorgio Perotto and manufactured by Olivetti. About 44,000 Programma 101 computers were sold, each with a price tag of $3,200. -
The first microprocessor
Intel introduces the first microprocessor, the Intel 4004 on November 15, 1971. -
The first micro-computer
The Vietnamese-French engineer, André Truong Trong Thi, along with Francois Gernelle, developed the Micral computer in 1973. Considered as the first "micro-computer", it used the Intel 8008 processor and was the first commercial non-assembly computer. It originally sold for $1,750. -
The first workstation
Although it was never sold, the first workstation is considered to be the Xerox Alto, introduced in 1974. The computer was revolutionary for its time and included a fully functional computer, display, and mouse. The computer operated like many computers today utilizing windows, menus and icons as an interface to its operating system. Many of the computer's capabilities were first demonstrated in The Mother of All Demos by Douglas Engelbart on December 9, 1968.
