Charles Babbage created the analytical engine
The Analytical Engine was a proposed mechanical general-purpose computer designed by English mathematician Charles Babbage.
The Analytical Engine incorporated an arithmetic logic unit, making it the first design for a general-purpose computer that could be described in modern terms as Turing-complete. -

Konrad Zuse invented the Z3 computer
It was the world's first working programmable, fully automatic digital computer. It was an electromechanical computer that used telephone relays and was the first computer to use a binary sistem. -
John Atanaoff, ABC computer
The ABC was one of the first electronic digital computing devices. The ABC used important elements of modern computing, like binary arithmetic and electronic switching elements,but its special-purpose nature and lack of a changeable, stored program distinguish it from modern computers. -
Harvard Mark 1
Mark I was a general purpose electro-mechanical computer that was used in the war effort during the last part of World War II. -
ENIAC
ENIAC was the first electronic general-purpose computer. It was digital, and capable of being reprogrammed. It had a speed of one thousand times that of electro-mechanical machines. -
EDVAC
EDVAC was one of the earliest electronic computers. Unlike its predecessor the ENIAC, it was binary rather than decimal, and was a stored program computer, had a maagntic tape reader-recorder and used a lot of vacunes. -
UNIVAC
The UNIVAC I was the second commercial computer produced in the United States. It was designed principally by the inventors of the ENIAC.In the years before successor models of the UNIVAC I appeared, the machine was simply know as "the UNIVAC"
UNIVAC was the first computer to use buffer memory. -
IBM 701
The IBM 701, was IBM’s first commercial scientific computer. They replaced the memory with a core memory. -
IBM 704
Like the 701, the 704 used vacuum tube logic circuitry. Changes from the 701 included the use of core memory.
he programming languages FORTRAN[3] and LISP[4] were first developed for the 704. -
PDP1
It was the first interactive comercial computer to use transistors. -
Jack Kilby designed integrated circuits
Is a set of electronic circuits on one small plate ("chip") of semiconductor material, normally silicon. This can be made much smaller than a discrete circuit made from independent components. The first customer for the new invention was the US Air Force. -
IBM System 360
System/360 was extremely successful in the market, allowing customers to upgrade it or purchase a smaller system if they wanted to. -
Bill Gates and Paul Allen founded microsoft
After they developed a software for ALTAIR BASIC, they founde microsoft in 1975 with Gates as the ceo. -
Apple released macintosh computer
The macintosh computer was designed for the average customer in 1983. People were dissapointed by personal computers, but this only started a competition with the IBM that payed microsoft to create windows, making the IBM more in demmand.
