That is, the programmer specifies what has to be done (i.e., what the output should be) instead of how the task is to be performed. 10 Feb. ... Ans. Use of IC in the computer provides the small size of the computer. FORTRAN is still useful, but its domain is limited to what is now one of the smallest application spaces: very high performance scientific computing. One definition of a fourth generation language (4GL) is that it is non-procedural language. The fourth generation computers are characterized by microprocessors, which contain a large number of integrated circuits (IC). IC not only reduce the size of the computer but it also improves the performance of the computer as compared to previous computers. Computers of fourth generation used Very Large Scale Integrated (VLSI) circuits. Wider commercial use; Better portability as compared to the first generation computers. Advantages: These computers were cheaper as compared to second-generation computers. Disadvantages of 3rd Generation Computers: Air conditioning was needed. Hard to maintain the Integrated circuits. The examples of second generation computers are IBM 7094 series, IBM 1400 series and CDC 164 etc. The main advantages are, Due to the VLSI technology, the computer was very small in size. Disadvantage of fourth generation computer: Advantages of Fourth Generation Computer. The fourth generation computers are also portable and more reliable. They generate much lesser heat and require less maintenance compared … Distributed operating systems and high level language like … They were fast and reliable. Advantages. This technology used a microprocessor instead of integrated circuits. FORTRAN/LISP: Lack of knowledge about the direction of computing progress. Heat generated is … All computer generations have some advantage and disadvantage today we explain some computer generation advantages and disadvantages. LISP gave birth to … This generation of computers … Smaller in size as compared to the first generation computers. Smallest in size because of high component density. The 2nd generation Computers were m ore reliable ; Used less energy and were not heated. The period of fourth generation was from 1971-1980. Very cheap as compared to previous generation computers. Discuss fourth generation languages with its advantages and disadvantages. (2) Small, affordable, reliable and easy-to-use. There were many advantages to fourth generations computers. 1975-1989 was the period of fourth-generation computers. (4) Fourth-Generation Of Computers. Listed below are advantages of fourth generation computer: (1) Practically maintenance -free. Advantages of the fourth generation of computer. Very reliable. The computers of the fourth generation use large scale integration which means a lot of integrated components can fit on the same piece of board that it would have been in compared to the third generation (3) Easier to produce commercially. The first microprocessor chip, Intel 4004 chip, was developed in 1971. (5) Rapid software development possible. Fourth Generation of Computer ( 1971 to present ) The microprocessor has resulted in the fourth generation computers being smaller and cheaper than their predecessors. advantages and disadvantages of 4th generation computer. Fourth Generation Computers- Some of the advantages of fourth generations computers are as follows- The use of LSI, VLSI and semiconductor technologies made these computers very powerful in terms of … VLSI circuits having about 5000 transistors and other circuit elements with their associated circuits on a single chip made it possible to have microcomputers of fourth generation. ... then a … Advantages.
