Fourth Generation: Microprocessors (1971-Present) The microprocessor brought the fourth generation of computers, as thousands of integrated circuits were built onto a single silicon chip. First Generation Language (Machine language) The first generation programming language is also called low-level programming language because they were used to program the computer system at a very low level of abstraction. 5) A Further refinement of input/output devices was developed. Much smaller size. ? Characteristics of the fourth generation of computers. These are used mainly in … The fourth generation of computers was introduced in 1971. More laptops. A characteristic of many fourth-generation languages is that they are declarative rather than procedural: programs written in the language describe what is be done rather than containing a sequence of instructions for doing it. Third-generation languages include C++ and Java, so, YES, you can say that a third generation language can be OOP. Very large scale integration is a process where a thousand transistors are combined into a chip to create an integrated circuit. Thanks to this, they had other advantageous features: Much less expensive. They were developed for totally general purpose use (general-purpose computers). Today high level language or fourth generation language is the result of extensive research in developing programming to make programming more efficient and it is used universal. 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. The most important characteristic of fourth generation computers is undoubtedly their size, which was due to the use of microprocessor technology / VLSI. Fourth Generation Languages : These are languages that consist of statements that are similar to statements in the human language. They used the very large scale integrated (VLSI) circuits, which developed from small integrated circuits. 4) Many high-level languages were developed in the fourth generation such as COBOL, FORTRAN, BASIC, PASCAL and C language. Some advantages and disadvantages of this language as follows: Advantages: It is machine independent (portability). In the following 8 points you get all the important characteristics of a Second generation computer and if you know some other important […] i.e. The following dBASE example shows the difference in syntax to open a customer file and display names and cities. Advantages and Disadvantages of the Fourth Generation of Computer. Features of the fourth generation computer are: Technology in use: VLSI is introduced and used Microprocessor-based technology. Most 4GLs are used to access databases. This technology allows thousands of integrated circuits to be built on a single silicon chip. Though there are some applications, such as voice recognition, that is being used today to make things easier. These processes are often compiled procedures and functions that are invoked when needed by the user. Fifth-Generation Programming Languages. Credit: sciencedirect.com. It is a third generation language or procedural language. Mercury is a purely 5th generation logical programming language. Upload files to the player??? And, also a structural oriented language and functional language. Fourth generation (1971-present) The fourth generation of computers is defined by microprocessors. Semiconductor like RAM, ROM and cache memory is used as a primary memory. Disclaimer. It is a step above assembly language and a step below a fourth-generation language (4GL). Here we will discuss some 5th generation programming language advantages its features.
