The second
computer generation: Transistors
The second
generation of computers starting from the transistors.
The biggest
change in the first electronic computer caused the replacement of vacuum tubes
by transistors. Transistors are smaller, cheaper, and smaller heat dissipation
compared with vacuum tubes. If the vacuum tubes require a wire, plate, metal,
glass and vacuum capsule, the transistor is a solid device (solid-state-device)
which is made of silicon.
Ttransistor
invented at Bell Labs in 1947 and in 1950 had launched the electronic
revolution. But it was not until the late 1950s, computers were entirely made
with transistors are already commercially available. The use of the transistor
determines the second generation computers. It was agreed that the computer
classification is based on the fundamental hardware technology used. Here's a
brief resume of generation computer generation.
Generation
1, year 1946 to 1957 using vacuum technology with 40,000 operations per second.
Generation
2, years 1958-1964 using transistor technology with 200,000 operations per
second.
Generation 3
years from 1965 to 1971 using the technology of small and medium scale
integration operations per second with 1,000,000.
Generation
4, years 1972-1977 using large scale integration technology with 10 million
operations per second.
Generation
5, 1978 and so on, using very large scale integration technologies.
