Tube computer (also referred to as tube machine , electronic computer or obsolete as electronic brain or electronic brain ) as a computer of the first generation referred, were built from the 1940s to the early 1960s and are made at the central switching elements of electron tubes . The most famous tube computers are the ENIAC (USA) and the Colossus (Great Britain). The Zuse Z22 , the PERM and the D1 and D2 from the GDR were particularly relevant for Germany .
Characteristic for this historical type of computer compared to the following computer systems were large dimensions from a few meters to a few tens of meters, a high power requirement in the range of a few tens of kW and a latent susceptibility to failure. Tube computers represent the transition between analog computers and mini-computers based on semiconductor technology .
