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. -
-
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.
-
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.
-
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 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 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.
-
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. -
The IBM 701, was IBM’s first commercial scientific computer. They replaced the memory with a core memory.
-
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. -
It was the first interactive comercial computer to use transistors.
-
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.
-
System/360 was extremely successful in the market, allowing customers to upgrade it or purchase a smaller system if they wanted to.
-
After they developed a software for ALTAIR BASIC, they founde microsoft in 1975 with Gates as the ceo.
-
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.
