The document summarizes the history of computing technology from 1946 to 1950. It describes the invention of the transistor in 1947, the founding of ISQ and IBM building the SSEC in 1947-1948. In 1949, Claude Shannon built the first machine that could play chess. The first electronic computer was created in Japan by Hideo Yamachito in 1950.
