The Zuse Z1
The Z1 is considered as the first programmable electro-mechanical computer in the world. It was designed by the German engineer Konrad Zuse between 1935 and 1936, built between 1936 and 1938, and destroyed along with all its construction plans in December 1943 during the Allied bombing of Berlin in World War II. -
The Zuse Z2
The Z2 computer, created by Konrad Zuse between 1938 and 1939, was designed from the Z1, since creating a mechanical machine presented some difficulties, and telephone relays were added to it -
Period: to
1º Generation
The first generation of computers were usually built by hand using circuits that contained relays and vacuum tubes, and often used punched cards or punched paper tape for input and as a means of main storage (non-volatile). -
The Zuse Z3
The Z3 computer, created by Konrad Zuse in 1941, was the first programmable and fully automatic machine, characteristics used to define a computer. -
The Mark I
The IBM Automatic Sequence Controlled Calculator (ASCC), better known as Harvard Mark I or Mark I, was the first electromechanical computer, built at IBM and shipped to Harvard in 1947. It had 760,000 wheels and 800 kilometers of cable and was machine-based Analytic of Charles Babbage. -
The Zuse Z4
The Z4 computer, designed by the German engineer Konrad Zuse and built by his company Zuse KG between 1941 and 1945, was delivered to ETH Zürich in Switzerland in September 1950.1 It was the first computer in the world to be sold, beating the British Ferranti Mark I for five months and UNIVAC I for ten months. The Z4 was the final result of Zuse for the design of the Z3. Like the Z3, it was an electromechanical machine. -
The IBM 701
The IBM 701 Electronic Data Processing Machine, known as the Defense Calculator while in development, was IBM’s first commercial scientific computer, which was announced to the public on April 29, 1952.[1] It was designed by Nathaniel Rochester and based on the IAS machine at Princeton.[2] Its successor was the IBM 704, its computer siblings were the IBM 702 for business, and the lower-cost general-purpose IBM 650. -
The Zuse Z22
The Z22 was the seventh computer model developed by Konrad Zuse (the first six were the computers Z1, Z2, Z3, Z4, Z5 and Z11, respectively). The biggest jump between Z11 and Z22 was the use of vacuum tubes, unlike previous models that used electromechanical devices. It was a commercial computer, and its design was completed in 1955. The first machines were sold to Berlin and Aachen. -
The First Operative Sistem
The first operating system in history was created in 1956 for an IBM 704 computer, and basically all it did was start the execution of a program when the previous one finished. ... It is in this decade when UNIX appears, the basis of the vast majority of the Operating Systems that exist today.
