forget about outer space...a lot of indoor space.
no, first generation computers used vacuum tubes.
They are first generation computers because they used vacuum tubes as active elements, as did almost all computers until 1958 when the first generation is usually considered to have ended. From 1958 on most computers used discrete transistors as active elements until 1964.Note: ABC & ENIAC are both very early first generation computers as they used ordinary Radio receiver vacuum tubes, not the more expensive Computervacuum tubes that were introduced about 1948 to 1949. The later Computer vacuum tubes were custom redesigned versions and were far more reliable than ordinary Radio vacuum tubes had been.
some first generation computers used germanium point contact diodes in their logic gates to reduce their vacuum tube parts count.second generation computers used discrete germanium or silicon transistors.third generation and later computers use silicon integrated circuits.
First generation computers were built with vacuum tubes. The capabilities were about the same as that of modern computers, except limited by very small memories and slow speed. Typical first generation computer memory cost from $2 to $20 per byte equivalent, whereas today's computer memory costs less than a micro-penny per byte.
vacuum tubes are the switching components in the first generation computers to process data. later they were replaced by transistors.
