Vacuum tubes generated too much heat, were very large, and proved to be unreliable. An electronic transistor is a semiconductor device used to amplify the electrical energy and signal of the circuit in which it is installed. Although atomic scientists weren’t completely satisfied by their second generation computers, businesses were able to afford and be productive with them instead. Other articles where Second-generation computer is discussed: computer: The IBM 360: ���are commonly referred to as second-generation computers. However, among its disadvantages has been found some sensitivity to radiation and short but powerful electrical or thermal shocks that may affect the device. Aside from the change in the use of transistors, resulting in much smaller, lighter and more efficient equipment, another of the great qualities presented by the second generation of computers was the development and use of the first outlines of the programming language, rather than common In current computing. The transition from tubes, or vacuum valves to the electronic transistor was the starting point of what is known as the second generation of computers, or what would be the first step towards digital computing. It was the commercial enterprises that managed to make better use of the second generation of computers, due to their effective integration between a new and more accessible programming language, and the first programs (or software) to fulfill specific functions; Which could be replaced or modified according to what was needed from the computer. The main novelty of the second generation of computers was the change of vacuum tubes (large size and dependent on thermionic energy, which generated large amounts of heat and low level of performance), by electronic transistors, which allowed an improvement in Performance and other aspects. A second generation of computers, through the late 1950s and 1960s featured circuit boards filled with ��� Two of the earliest and most popular programming languages were FORTRAN (Formula Translator) and COBOL (Common Business Oriented Language). Second-Generation Computers (1959���1964) In the second-generation computers, transistors were used instead of vacuum tubes. The second generation computers used Transistors. The second generation put into practice a new language that allowed the insertion of instructions through words. Find out inside PCMag's comprehensive tech and computer-related encyclopedia. IBM was one of the companies that best managed to position itself and its products during this period, being closer and friendly to the general consumer. Programming is what made the first generation computer different from previous inventions, and it improved in the second generation computers. Where a vacuum tube was used before, a hundred transistors could be integrated. Technological advances in the field of computing began to advance faster and faster from this stage. This allowed for the specific instructions, beyond simple language, that the computer could respond to. The mid-twentieth century marked the development of second-generation computers, which began to display the advancements in technology that we are familiar with today.
