  • Wicki Zuse Essay

    By the age of seventeen he was able to gain entrance to Berlin’s Charolttenburg Technical College, majoring in civil engineering. He was a gifted in artistry and technology, it was there he developed ideas for up the first universal computer. After leaving a job as a structural engineer, Zuse spent time making early versions of computing devices known as the Z1. With the help of his friends, the machine was built out of scrap metal and glass parts. At the start of the war in 1939 he built two successive versions, the Z2 and Z3. Following, he was drafted into the army as an infantryman for 6 months until German officers thought he would suit better developing flying bombs for the army. There, he improved his model the Z3 which was a computer built with electromagnetic relays, included binary numbering system as well as floating point numbers, and used punched film tape. After completion of the Z3 Zuse was again drafted to the army and excused to develop computers again. After his developments of computers, Zuse was inspired to start something new. He developed Plankalkul or plan calculus, which was one of the first algorithmic language. Designed for chess playing, the language utilized both numerical and non-numerical problems in a matrix. While it was difficult to read on several formats, it was something ahead of its time for software development.…

  • 1930s And 40s: The Development Of Modern Computing

    The overall function and design was similar to that of the Z1. Although the Z3 had similar functionality to the Z1, the Z3 had more features such as new arithmetic operations and square root operations. The machine was far more dependable and didn’t need constant maintenance to continue operating. Just as early models of the Z1 and Z2 were destroyed during the war, so was the original Z3. The Z3 was later recreated in the 60s by Zuse and some engineers from his company. The remake of the Z3 was…

  • Konrad Zuse: The First Automatic Calculating Machine

    films to store the program instead of paper tape or punch cards. Z3 had the clock speed of 5Hz that was faster than the 3Hz clock speed of the Z2 and could do addition and subtraction in less than a second. It could store program instruction unlike its predecessors, solving the problem of inputting the program every time before using it. Z3 could also convert decimals to binaries and back again. It was later on proven to be Turing complete, which means that given the; appropriate algorithms,…

  • Theoretical Analysis For Hphx's Performance

    on the heat pipe internal and external diameters, evaporation length, condensation length, and the pipes thermal conductivity. Z3 and Z7 are the internal thermal resistances of the boiling and condensing fluid inside the tubes. They also depend on the size of the pipe, the evaporation and condensation lengths, and the types of the fluids. Z4 and Z6 are the internal thermal resistances at the vapor-liquid interface in the evaporator and the condenser respectively. These are always neglected being…

  • The Third Generation Of Technology: The History Of Computing Technology

    generation computers, the transistor classified the second, integrated circuits categorized the third generation and that the microprocessor outlined the fourth. The text also suggests that modern technology belongs to a fifth generation of computing, which may have been the result of “rampant computer networking,” during the 1990’s. 1. During first generation computing, vacuum tubes served as the most relevant technology. While computational devices such as the difference engine, and computer…

  • Theories Behind Computers Essay

    of relays and vacuum tubes, digital computers were soon in production. In 1936, Alan Turing presented the concept of the general computer with an integrated memory that he called the Turing machine that became a reality in 1941 when Alanstoff-berry computer was developed by J.V. Alanstoff and Clifford Berry. This was the first computer that was able to calculate multiple equations at the same time and have an integrated memory system. During the same time, Konrad Zuse was working on a…
