Presentation on theme: "The first computer was invented in Unfortunately Zuse died in The term debug came about long before the internet was invented. It was originated by the term debugging. It was attributed to Admiral Grace Hopper in the s.
While she was working on a Mark II computer at Harvard University, her associates discovered a moth stuck in a relay and thereby impeding operation, whereupon she remarked that they were debugging the system. Thankfully, the internet started in , when the Soviet Union launched Sputnik 1 the first satellite , beating the United States into space. It was started because, it was known as the American defense system.
The internet was invented by the US Department of Defense. The design of a mechanical general-purpose computer by English mathematician Charles Babbage. The machine was essentially modern, anticipating the first completed general-purpose computers by about years. It was the first described in Herman Holleriths machine was designed to assist in summarizing information and, later, accounting. It was developed to help process data for the U. The Eniac was built for calculating artillery firing tables for the United States Armys Ballistic Research Laboratory, but its first use was in calculations for the hydrogen bomb.
When it was announced in , it was known as a Giant Brain. The original Z3 was destroyed on 21 December during an Allied bombardment of Berlin. That Z3 was originally called V3 Versuchsmodell 3 or Experimental Model 3 but was renamed so that it would not be confused with Germany's V-weapons. The Z3 was demonstrated in to be, in principle, Turing-complete. Thanks to this machine and its predecessors, Konrad Zuse has often been suggested as the inventor of the computer. Zuse designed the Z1 in to and built it from to The Z1 was wholly mechanical and only worked for a few minutes at a time at most.
Helmut Schreyer advised Zuse to use a different technology. As a doctoral student at the Berlin Institute of Technology in he worked on the implementation of Boolean operations and in today's terminology flip-flops on the basis of vacuum tubes.
In Schreyer demonstrated a circuit on this basis to a small audience, and explained his vision of an electronic computing machine — but since the largest operational electronic devices contained far fewer tubes this was considered practically infeasible.
Zuse decided to implement the next design based on relays. The realization of the Z2 was helped financially by Kurt Pannke , who manufactured small calculating machines.
Zuse was lucky — this presentation was one of the few instances where the Z2 actually worked and could convince the DVL to partly finance the next design.
Improving on the basic Z2 machine, he built the Z3 in , which was a highly secret project of the German government.
The Z3 was completed in and was faster and far more reliable than the Z1 and Z2. The Z3 floating-point arithmetic was improved over that of the Z1 in that it implemented exception handling "using just a few relays", the exceptional values plus infinity, minus infinity and undefined could be generated and passed through operations.
