2ng generation. It used transistors and magnetic core memory
first generation used vacuum tubes second generation used transistors
second generation of computing
discrete transistors, usually made of germanium.
Vacuum tubes are used in first generation computers and transistors are used in second generation computers. Second generation computers are ten times faster than the first generation.
Second generation computers used electronic transistors. A small number used magnetic amplifiers.
FIrst generation- vacuum tubes 2nd generation- transistors 3rd generation- microchips 4th generation-integrated circuits 5th generation-artificial intelligence
Each computer generation had different characteristics. The first generation used vacuum tubes, the second used transistors, the third used integrated circuits, and the fourth uses microprocessors. The fifth generation is still developing and will use artificial intelligence.
the major features of second generation computer are :transistors were used as a memory deviceprocessing speed was measured in microsecond
In second generation of computer transistors were used Transistors were took place instead of vaccume tubes in 1st generation High lever languages were used such as COBSL , FORTRAN and these were still used for some application Many finanacial programms were used in this computers In 2nd generation of computer the instructions was stored inside the computer memory Out standing features for 2nd generation of computer 1 very small in size 2 less expensive 3 more storage capacity 4 reduction of heat 5 faster speed
the transistors were usedthe core memory was developedprogramming was in machine languagemagnetic taps and disc
no, second generation. third generation computers used ICs.
Transistors ran cooler than Vacuum tubes.
the transistor is on the second generations
First Generation- 1945-1956-Atansoff berry Computer. Second Generation-1956-1963-Transistors. Third Generation-1964-1971-Integrated circuits. Fourth Generation-1971-Present-Apple Macintosh.
A second generation computer was made of a board filled with individual transistors and magnetic memory cones. This occurred in the late 1950's and 1960's.
making the transistors that run your computer
The size of computers was reduced in third generation computer because the Integrated Circuits allowed 10 or more transistors per package unlike the one transistor that was allowed in the second generation.
Varied widely depending on requirements of the computer.The IBM 1620 a small scientific computer had from 1500 to 5000 transistors in the CPU depending on options included.The IBM 1401 a small business computer had about 10000 transistors in its CPU.The IBM 7030 Stretch a supercomputer had about 170000 transistors.The CDC 6600 a supercomputer had about 384000 transistors.The CDC 7600 a supercomputer had about 2900000 transistors.You can compare this to first generation computers, the largest of which the IBM AN/FSQ-7 had about 50000 vacuum tubes.You can compare this to modern multicore microprocessor based computers, a typical one of which has a couple hundred billion transistors per processor core integrated on one chip.
Fourth Generation Computers (which are Microprocessors) were invented through the development of Transistors. Transistors were created by William Shockley, John Bardeen and Walter Brarttain. Therefore, it is hard to tell a specific inventor of the Microprocessor.
The second generation computers emerged with the development of transistors. The first of the second generation of computers was invented in 1956 by Sir Charles Romanseys.
Several early digital computers were made of electromechanical devices similar to those used to build automatic dial telephone exchanges used at the time. First generation digital computers were made of vacuum tubes. Second generation digital computers were made of discrete transistors (most used germanium transistors but later some silicon transistors). Third generation digital computers were made of (hybrid, SSI, MSI, LSI) silicon integrated circuits. Fourth generation digital computers are made of microprocessors and other (VLSI, ULSI, etc.) silicon integrated circuits.
Mostly the machines got smaller and more reliable as transistors replaced vacuum tubes.
