A transistor computer, now often called a second-generation computer, [1] is a computer which uses discrete transistors instead of vacuum tubes. The first generation of electronic computers used vacuum tubes, which generated large amounts of heat, were bulky and unreliable.
Listed are many semiconductor scale examples for various metal–oxide–semiconductor field-effect transistor (MOSFET, or MOS transistor) semiconductor manufacturing process nodes. Timeline of MOSFET demonstrations
For the purposes of this article, the term "second generation" refers to computers using discrete transistors, even when the vendors referred to them as "third-generation". By 1960 transistorized computers were replacing vacuum tube computers, offering lower cost, higher speeds, and reduced power consumption.
Flyable TRADIC was used to establish the feasibility of using an airborne solid-state computer as the control element of a bombing and navigation system. Leprechaun [6] [7] [8] was a second-generation laboratory research transistor digital computer designed to explore direct-coupled transistor logic (DCTL). The TRADIC Phase One computer was ...
Second generation computer, a computer constructed using discrete transistors; Second generation of video game consoles (1976–1984), sometimes referred to as the early 8-bit era; Second Generation Multiplex Plus, DNA profiling system; Second-generation programming language, a generational way to categorise assembly languages
This is a list of transistorized computers, which were digital computers that used discrete transistors as their primary logic elements. Discrete transistors were a feature of logic design for computers from about 1960, when reliable transistors became economically available, until monolithic integrated circuits displaced them in the 1970s.
A second-order partial differential equation that describes the propagation of electromagnetic waves through a medium or in a vacuum. electromagnetism The science of electric fields, magnetic fields, currents, charges, and forces. electromechanical A system that has both an electrical component and a mechanical component, such as a motor or a ...
Computers introduced between 1959 and 1964, often regarded as second-generation computers, were based on discrete transistors and printed circuits – resulting in smaller, more powerful and more reliable computers. 1959 UK
