FRAGE 6: What's the name of the world's first programmable electronic digital computer?
Tipp: Die Antwort ist nicht ENIAC oder IBM.
ANTWORT: Der Z3-Computer von Konrad Zuse im Jahre 1941. - Konrad Zuse's Z3 computer in 1941.
The pioneering Z3 had 2600 relays, used punched tape for data entry, and featured an error-detecting code. The Z3 is considered to be the world's first working programmable computer. (Zuse's Z4, begun in 1945, was even more advanced.) The IBM Mark I (ASCC) computer at Harvard was not built until 1944 and broke down frequently. The ENIAC of 1946, the first all-electronic computer, was not binary. Its 18,000 vacuum tubes drew so much current that it dimmed the lights of an entire town. The invention of the transistor in 1947 would revolutionize the computer and all electronics, but the first transistorized computer did appear until 1955.
