From 1955 onwards transistors replaced vacuum tubes in computer designs, giving rise to the "second generation" of computers. Even if the removable disks' capacity is smaller than fixed disks, their interchangeability guarantees a nearly unlimited quantity of data close at hand. » Used faster peripherals. Transistors … The main technology for Second Generation was transistors (1956-1963). However, it still required valves to generate the clock waveforms at 125 kHz and to read and write on the magnetic drum memory, whereas the Harwell CADET operated without any valves by using a lower clock frequency, of 58 kHz when it became operational in February 1955. Second-generation computers used _____ to process data. 3. » Used assembly language as well. 6. The first generation of computer is introduced in 1946. The

Well-known … » Better speed and could calculate data in microseconds. CDC 1604
On the PDP-1, the core memory's cycle time was 5 microseconds; consequently most arithmetic instructions took 10 microseconds (100,000 operations per second) because most operations took at least two memory cycles; one for the instruction, one for the operand data fetch. For example, while the communication processor controlled card reading and punching, the main CPU executed calculations and binary branch instructions. The period of second generation was from 1956 to 1963. The success of the VAX family of computers transformed DEC into the second-largest computer company in the world, as VAX systems became the de facto standard computing system for industry, the sciences, engineering, and research. From 1955 onwards, transistors replaced vacuum tubes in computer designs, giving rise to the "second generation" of the computer. They required much less power. IBM 7094

The IBM 7094 is the computer of the second generation. Transistorized electronics improved not only the CPU (Central Processing Unit), but also the peripheral devices. [87] Problems with the reliability of early batches of point contact and alloyed junction transistors meant that the machine'smean time between failures was about 90 minutes, but this improved once the more reliable bipolar junction transistors became available. Vacuum tubes generated too much heat, were very … Computer Mouse and GUI make computers more enjoyable. Transistors greatly reduced computers' size, initial cost, and operating cost. Transistors were smaller than vacuum tubes and allowed computers to be smaller in size, faster in speed, and cheaper to build. Vacuum tubes were used as an internal component. A transistor computer, now often called a second generation computer, is a computer which uses discrete transistors instead of vacuum tubes. During the second generation remote terminal units (often in the form of teletype machines like a Friden Flexowriter) saw greatly increased use.Telephone connections provided sufficient speed for early remote terminals and allowed hundreds of kilometers separation between remote-terminals and the computing center.
