First generation computer(1946-1955) first generation computer uses vacuum tubes, magnetic tape drives and magnetic core memories were developed eniac (electronic numeric integrator and calculator ) was the first electronic digital computer. The third generation was based on ic technology and the computers that were designed with the use of integrated circuits were called third generation computers advantages: smaller in size as compared to previous generation computers. The first generation computers were used during 1942-1955 they were based on vacuum tubes examples of first generation computers are enivac and univac-1. Eniac (electronic numerical integrator and computer): one of the first totally electronic, valve driven, digital, computers development started in 1943 and finished in 1946, at the ballistic research laboratory, usa, by john w mauchly and j presper eckert.
First-generation computers did not have the capacity to store its instructions internally second-generation computers, however, had the ability to store its usage instructions in its memory, which had advanced from magnetic drum to magnetic core technology. Their generation computers- the following are the advantages of third generation computer they were the fastest computing devices as compared with first and second generation of computers the computational time for these computers was also reduced to great extent. Some computer historians argue that the first generation actually started in 1949 others define the beginning of the first generation of computers as starting with the first computer that was offered for sale, or commercially available.
Advantages of secound generatin of computer: » smaller in size compared to the first generation of computer » the second generations computers were more reliable. First generation: vacuum tubes (1940-1956) the first computer systems used vacuum tubes for circuitry and magnetic drums for memory, and were often enormous, taking up entire roomsthese computers were very expensive to operate and in addition to using a great deal of electricity, the first computers generated a lot of heat, which was often the cause of malfunctions. The size of second generation computers is small compared to the size of first generation computers the cost is low maintenance cost of second generation computers is low because hardware failures are rare. Advantages of first generation of computers generation of computers the term generation indicates the type of technology used in the computer construction as new technology was emerging, it was being used in the making of computerthe new technology improved the speed, accuracy and storage capacity of the computersdifferent technologies have been used for computers in different times.
The first electronic computers were built during the second world war to decrypt german coded signals the advantages of the earliest computers is that they could perform thousands of calculations. The first generation computers had a speed of 5mbps while the second generation computers had a speed of 10mbps (oderog, a, 2010) from this it can be observed that second generation computers were twice as fast as the first generation computers with respect to processing of information and also carrying out of operations. Fifth generation computers (in process)the main drawback of first to fourth generation computers is that the computers have not theirown thinking power these are totally depending upon the instructions given by the usersfifth generation computers are supposed to be the ideal computers, but do not exist. The third generation computers used theintegrated circuits (ic) jack kilby developed the concept of integrated circuit in 1958 it was an important invention in the computer field the first ic was invented and used in 1961.
Generations, computers early modern computers are typically grouped into four generations each generation is marked by improvements in basic technology these improvements in technology have been extraordinary and each advance has resulted in computers of lower cost, higher speed, greater memory capacity, and smaller size. Warnock believes there are two solutions to the barriers first generation college students face: identification and support of these students, and more financial aid. The first generation of computers the first generation of computers, beginning around the end of world war 2, and continuing until around the year 1957, included computers that used vacuum tubes, drum memories, and programming in machine code.
The history of computing hardware covers the developments from early simple devices to aid calculation to modern day computers before the 20th century, most calculations were done by humans before the 20th century, most calculations were done by humans. Let’s discuss the advantages and disadvantages of first generation computer first generation: on the first generation computer, there was vacuum tubes (1940-1956) on the first computer systemsthe main reason for using vacuum tubes on 1st generation computer for circuitry and magnetic drums for memory, and were often enormous, taking up entire rooms. The fifth generation computer systems [present and future] (fgcs) was an initiative by japan's ministry of international trade and industry, begun in 1982, to create a computer using massively parallel computing/processing it was to be the result of a massive government/industry research project in japan during the 1980s. He developed first micro-processor, the intel 4004, as he was working for intel corporation, usa with the use of microprocessor in the fourth generation computers, the size of computer become very fast and efficient.
First generation computers the first generation of computers is said by some to have started in 1946 with eniac, the first 'computer' to use electronic valves (ie vacuum tubes)others would say it started in may 1949 with the introduction of edsac, the first stored program computerwhichever, the distinguishing feature of the first generation computers was the use of electronic valves. The advantages of first generation of computer is : » these computers fast and could calculate data in millisecond » vacuum tubes were the only electronic component available during those days. 1)these computers are much faster than 1st,2nd,3rd,and4th generation computers 2)it is easier to repair these computers 3)these computers are much smaller in size than other generation computers.
