The pascaline
In 1642 Blaise Pascal, at age 19, invented the Pascaline as an aid for his father that was a tax collector. Pascal built 50 of this gear-driven one-function calculator (it could only add) but couldn´t sell many because of their exorbitant cost and because they really weren´t that accurate. -
Isaac Newton describes Newton’s method
Isaac Newton describes Newton’s method.
Isaac Newton describes Newton’s method, an early numerical algorithm for finding roots of equations (also known as the Newton–Raphson method) -
Binary logic
In 1702, Gottfried Wilhelm Leibnitz developed logic in a formal, mathematical sense with his writings on the binary numeral system. In his system, the ones and zeros also represent true and false values or on and off states. But it took more than a century before George Boole published his Boolean algebra in 1854 with a complete system that allowed computational processes to be mathematically modeled -
Analytical Engine
Charles Babbage invets the analytical engine.The Analytical Engine was, or would have been, the world's first general-purpose computer. The Analytical Engine introduced a number of computing concepts still in -
Logarithm
When John Napier discovers the logarithms for the calculus, A logarithm is the power to which a number must be raised in order to get some other number -
The first computer algorithm
Ada Lovelace develops the first computer algorithm, what she did was write the world’s first machine algorithm for an early computing machine that existed only on paper. Of course, someone had to be the first, but Lovelace was a women. -
The Turin Machine
Manipulates symbols on a strip of tape according to a table of rules; to be more exact, it is a mathematical model that defines such a device.Despite the model's simplicity, given any computer algorithm, a Turing machine can be constructed that is capable of simulating that algorithm's logic. -
The transistors
Bell Labs invents the transistor.A transistor is a semiconductor device used to amplify and switch electronic signals and electrical power. -
The keyboard
In computing, a computer keyboard is a typewriter-style device, which uses an arrangement of buttons or keys, to act as mechanical levers or electronic switches. Following the decline of punch cards and paper tape, interaction via teleprinter-style keyboards became the main input device for computers. -
The computer mouse
Douglas Engelbart invents rhe computer mouse.In computing, a mouse is a pointing device that detects two-dimensional motion relative to a surface. This motion is typically translated into the motion of a pointer on a display, which allows for fine control of a graphical user interface. -
The Computer Science Department
It was created in January within the School of Humanities and Sciences with George Forsythe as chair. The department is authorized to grant master's and doctoral degrees. -
ARPAnet
The first operational computer network and ancestor of the internet was invented by DARPA.The Advanced Research Projects Agency Network (ARPANET) was an early packet switching network and the first network to implement the protocol suite . -
Kenbak-I ,the first personal computer sold in the USA
The Kenbak-1 is considered by the Computer History Museum and the American Computer Museum to be the world's first "personal computer".Only 40 machines were ever built and sold. It was designed and invented by John Blankenbaker of Kenbak Corporation in 1970. -
Single-board computer for hobbyists
A single-board computer (SBC) is a complete computer built on a single circuit board, with microprocessor(s), memory, input/output (I/O) and other features required of a functional computer. Single-board computers were made as demonstration or development systems, for educational systems, or for use as embedded computer controllers -
Apple 1
Apple Computer 1,also knew retroactively as the Apple-1,was released by the Apple Computer Company(now Apple Inc)in 1976.They were designed and hand-built by Steve Wozniak.Wozniak´s friend Steve Jobs had the idea of selling the computer -
The portable computer
A portable computer is a computer that is designed to be moved from one place to another and includes a display and keyboard. Portable computers, by their nature, are generally microcomputers.Portable computers, because of their size, are also commonly known as 'Lunchbox' or 'Luggable' computers. They can also be called a 'Portable Workstation' or 'Portable PC'. -
IBM,the first MS-DOS computer
IBM PC DOS ( Acronym for International Business Machines Corporation Personal Computer Disk Operating System) was an operating system for the IBM Personal Computer, manufactured and sold by IBM from the 1980s to the 2000s . -
Microsoft releases Windows 1.0
Windows 1.0 is a graphical personal computer operating environment developed by Microsoft. Microsoft (Bill Gates) had worked with Apple Computer (Steve Jobs) to develop applications for Apple's January 1984 original Macintosh, the first mass-produced personal computer with a graphical user interface. -
WorldWideWeb
Sir Tim Berners-Lee of CERN invents the WorldWideWeb.The World Wide Web is a system of Internet servers that supportspecially formatte documents . -
Mosaic
Marc Andresson create the mosaic, later known as Netscape the first popular user-friendly Web browser.NCSA Mosaic, or simply Mosaic, is a discontinued early web browser. It has been credited with popularizing the World Wide Web. It was also a client for earlier protocols such as FTP, NNTP, and gopher. The browser was named for its support of multiple internet protocols.
