Brattain Invented 2nd Generation Computer 2nd Generation Computer was invented between 1960–1964. A replica of the first transistor. less sensitive to temperature, so they cannot easily burn The ENIAC is a great example of a first generation computer. Examples are the IBM 7090 and 7094, UNIVAC 1107, PDP-1 and 8. The second generation emerged with transistors being the brain of the computer. The transistor was invented in 1947 but did not see widespread use in computers until the late 1950s. The main technology for Second Generation was transistors (1956-1963). This generation marked a new era that was defined by the replacement of vacuum valves by transistors, which implied the creation of more reliable computers with less ventilation needs, making them commercially accessible and powerful. for secondary memory and magnetic core for primary memory. According to this concept 5 generations have been defined: 1. A transistor computer, now often called a second generation computer, is a computer which uses discrete transistors instead of vacuum tubes. failures are rare. Vacuum tubes were larger components and resulted in first generation computers being quite large in size, taking up a lot of space in a room. Large companies began to use the computer for storage, registration, inventory management, payroll and accounting. operations in microsecond. Second generation computers also used magnetic core networks instead of rotating drums for primary storage. It used a magnetic core memory with more than 60,000 decimal digits. The transistor was far superior to the vacuum tube, allowing computers to become smaller, faster, cheaper, more energy-efficient and more reliable than their first-generation predecessors. They were built with transistor electronics. The main second generation computers included: 1. It proved to be a popular scientific computer reaching sales of approximately 2000 units. UNIVAC 1107 – It was made by Sperry Rand in 1962. It consiste… The input t. Perform Second They were more powerful, more reliable, less expensive, smaller, and cooler to operate than the first-generation computers. This transistor-based equipment used a perforated paper ribbon which quickly changed to punched cards. generation computers used magnetic tapes, magnetic disks conditioning is required. Computers are such an integral part of our everyday life now most people take them and what they … Writing First generation: 1942-1958. The first generation of computers generated in the mid-twentieth century had the first indication or antecedent of modern computers, but among its main characteristics were its large size as well as its high cost of acquisition, and the recurrent theme of failures and errors for being experimental. size of first generation computers. This generation marked a new era that was defined by the replacement of vacuum valves by transistors, which implied the creation of more reliable computers with less ventilation needs, making them commercially accessible and powerful. They replaced the job of vacuum tubes through the 1950s and 1960s. An impact large enough that they can be referred to as a generation of change. William Bradford Shockley (13/02/1910 – 12 /08/1989), the physicist Walter Houser Brattain (Amoy, China, 10/02/1902 – 13/10/1987), and the electrical and physical engineer John Bardeen (Madison, United States 23/05/1908 – Boston, 30/01/1991), were awarded the Nobel Prize in Physics in 1956. It used punched cards and a 4000 character magnetic core memory. 200 transistors could be accommodated in the same amount of space as a vacuum tube, a characteristic that made them faster, smaller, and more reliable. The second generation of computers covered the period from 1959 to 1964. The world saw transistor replaced the vacuum tubes in the second generation of computers. The first computers used vacuum tubes and occupied a considerable space (up to 30m long). It had a storage capacity of 5 megabytes of data. A directory of Objective Type Questions covering all the Computer Science subjects. Maintenance Physicists John Bardeen, Walter Brattain and William Shockley, who knowing the properties of the silicon found in quartz stones, after years of research finally conceived the transistor. A UNIVAC computer at the Census Bureau. The term was coined to provide a distinction from higher level machine independent third-generation programming languages (3GL) such as COBOL and earlier first-generation programming languages (machine code) Third generation: 1964-1972. was developed, the first computer game. The invention of the transistor made possible a new generation of computers with the following characteristics: The creation of transistors and their use in computer manufacturing, triggered a series of events in the history of computing, not only because it represented a significant technological advance, but also initiated a new stage in equipment commercialization. Third generation computers were developed around 1964 to 1971, though different sources contradict each other by one or two years. Transistors replaced vacuum tubes and ushered in the second generation of computers. given through punch cards and the output displayed as The second generation of computers covered the period from 1959 to 1964. Used for science and engineering as well as simple data processing, the LGP-30 was a “bargain” at less than $50,000 and an early example of a ‘personal computer,’ that is, a computer made … laboratories on 1947 by William Shockley, John Bardeen and The use of Transistors replaced vacuum tubes. The computers used batch processing and multiprogramming operating system. instructions in assembly language is easier than writing Transistors that are made from silicon are less sensitive to temperature, so they cannot easily burn up. They used networks of magnetic cores instead of rotating drums for primary storage, containing small rings of linked magnetic material in which data and instructions could be stored. generation computers used magnetic tapes, magnetic disks for secondary memory and magnetic core for primary memory. Image Source: United States Census Bureau. The many thousands of individual components had to be assembled by hand into functioning circuits. Computers developed between 1959-1965 the second generation computers. Operation based on vacuum tubes. A second generation computer was made of a board filled with individual transistors and magnetic memory cones. The first generation computers had a speed of 5mbps while the second generation computers had a speed of 10mbps (Oderog, A., 2010). Second-generation computers emerged in 1955 with the use of transistor instants of vacuum tubes in computers, and this generation lasted until 1965. Computers began to decrease in size, and small magnetic rings were used to store information and instructions. The second generation of computers were ones built with discrete transistors (roughly 1956 – 1963). With both the first and the second generation computers, the basic component was a discrete or separate entity. Second-generation computers were manufactured using transistors. The main features of second generation are − Use of transistors; Reliable in comparison to first generation computers; Smaller size as compared to first generation computers; Generated less heat as compared to first generation computers; Consumed less electricity as compared to first generation computers; Faster than first … In its normal state, the semi-conductor was not conductive, but when a certain voltage was applied to it, it became conductive and the electric current flowed through it.
