The loom is invented
In France, Joseph Marie Jacquard invents a loom that uses punched wooden cards to automatically weave fabric designs. Early computers would use similar punch cards. -
Calculating machine is invinted
English mathematician Charles Babbage conceives of a steam-driven calculating machine that would be able to compute tables of numbers. The project, funded by the English government, is a failure. More than a century later, however, the world’s first computer was actually built. -
The punch card is invented
Herman Hollerith designs a punch card system to calculate the 1880 census, accomplishing the task in just three years -
The Turing machine is invented
Alan Turing presents the notion of a universal machine, later called the Turing machine, capable of computing anything that is computable. -
Invents The first computer without gears, cams, belts or shafts.
J.V. Atanasoff, a professor of physics and mathematics at Iowa State University, attempts to build the first computer without gears, cams, belts or shafts. -
A new kind of computer is invented
: Atanasoff and his graduate student, Clifford Berry, design a computer that can solve 29 equations simultaneously. This marks the first time a computer is able to store information on its main memory. -
The Electronic Numerical Integrator
wo University of Pennsylvania professors, John Mauchly and J. Presper Eckert, build the Electronic Numerical Integrator and Calculator (ENIAC). Considered the grandfather of digital computers, it fills a 20-foot by 40-foot room and has 18,000 vacuum tubes. -
The electric switch is invented
William Shockley, John Bardeen and Walter Brattain of Bell Laboratories invent the transistor. They discovered how to make an electric switch with solid materials and no need for a vacuum. -
The first computer language is born
Grace Hopper develops the first computer language, which eventually becomes known as COBOL. Thomas Johnson Watson Jr., son of IBM CEO Thomas Johnson Watson Sr., conceives the IBM 701 EDPM to help the United Nations keep tabs on Korea during the war. -
The computer chip is invented
: Jack Kilby and Robert Noyce unveil the integrated circuit, known as the computer chip. Kilby was awarded the Nobel Prize in Physics in 2000 for his work. -
The modern computer is invented
Douglas Engelbart shows a prototype of the modern computer, with a mouse and a graphical user interface (GUI). This marks the evolution of the computer from a specialized machine for scientists and mathematicians to technology that is more accessible to the general public. -
The First Dynamic access memory
The newly formed Intel unveils the Intel 1103, the first Dynamic Access Memory (DRAM) chip. -
The floppy disk is invented
Alan Shugart leads a team of IBM engineers who invent the “floppy disk,” allowing data to be shared among computers. -
The Ethernet is invinted
: Robert Metcalfe, a member of the research staff for Xerox, develops Ethernet for connecting multiple computers and other hardware. -
Microsoft is born
The January issue of Popular Electronics magazine features the Altair 8080, described as the "world's first minicomputer kit to rival commercial models." Two "computer geeks," Paul Allen and Bill Gates, offer to write software for the Altair, using the new BASIC language. On April 4, after the success of this first endeavor, the two childhood friends form their own software company, Microsoft.
