Answers
Answer:
generation: Vacuum tubes (left). Mid 1940s, beginning with ENIAC. IBM pioneered the arrangment of vacuum tubes in pluggable modules such as the one shown in the photo. The IBM 650 (1953) was a first-generation computer, as were the pioneering IBM one-off SSEC (1948) and NORC (1954), both built by Columbia University's Watson Lab.
Second generation: Transistors (right). 1956. The era of miniaturization begins. Transistors are much smaller than vacuum tubes, draw less power, and generate less heat. Discrete transistors are soldered to circuit boards like the one shown, with interconnections accomplished by stencil-screened conductive patterns on the reverse side. The IBM 7090 was a second-generation computer.
Third generation: Integrated circuits (foreground), silicon chips contain multiple transistors. 1964. A pioneering example is the ACPX module used in the IBM 360/91, which, by stacking layers of silicon over a ceramic substrate, accommodated over 20 transistors per chip; the chips could be packed together onto a circuit board to achieve unheard-of logic densities. The IBM 360/91 was a hybrid second- and third-generation computer.
