The world would see transistors replace vacuum tubes within the second generation of computers. The junction transistor was unreal at Bell Labs in 1947 however didn’t see widespread use in computers till the late Fifties.
The junction transistor was so much superior to the tube, permitting computers to become smaller, faster, cheaper, a lot of energy-efficient and a lot of reliable than their first-generation predecessors. tho’ the junction transistor still generated an excellent deal of warmth that subjected the pc to break, it had been a massive improvement over the tube. Second-generation computers still relied on punched cards for input and printouts for output.
From Binary to Assembly
Second-generation computers rapt from cryptic binary machine language to symbolic, or assembly, languages, that allowed programmers to specify directions in words. High-level programming languages were additionally being developed at this point, like early versions of COBOL and algebraic language. These were additionally the primary computers that keep their directions in their memory, that rapt from a magnetic drum to core technology.
The first computers of this generation were developed for the energy business.
