Known as `tubes' in America. Valves were glass containers where electrodes where encased in a vacuum. E.g. a diode valve would have two electrodes, an anode and a cathode there would also be two pins for the heater. The heater would `boil' electrons off the cathode to be captured by the anode (clearly this would only work one way). A triode valve would also have a grid to control electrode flow, other valves with more grids for finer control would be named according to the number of electrodes discounting the heater pins in the count.

History of computer is divided into 5 generation. The first generation of computer started form 1941 till 1956. In this generation vacuum tubes are used in computers and computers are big enough that one computer could be such big as a whole room.
