We are also setting up a community for the users and students. Disadvantages: Programs run slower because it is heavy in size and design. It eventually connected hundreds... Read More, Ans. The fourth-generation computer programming language is easy to learn and debug. The rules for naming a function are same as for naming variables – Why does a fourth generation programming language provide a productivity improvement over a conventional third generation programming language? Machine language is not portable language. Programmers do not have to learn a new language for each computer they program. 4GLs are closer to human language than other high-level languages and are accessible to people without formal training as programmers.They allow multiple common operations to be performed with a single programmer-entered command. Programming productivity is increased. There was all round development in technology, designs and programming languages. at the machine level. Some 4GLs are aimed at the end user and ease of use is then a prime consideration, which could be described as very high level languages, are designed for use by professional computer experts, and their main objective is to cut down on development and maintenance time. Discuss fourth generation languages with its advantages and disadvantages. Program maintenance is easier. The very advanced technology was required to fabricate to the ICs (Integrated Circuits). A 4GL normally contains a utility software (tool) that interacts with the database management system (DBMS) software to store, manipulate and retrieve data needed to satisfy user requirements for information . Its time consuming to develop new programs. C language is the building block for many other currently known languages, It has a variety of data types and powerful operators, C program is basically the collection of functions that are supported by the C library, So you can add your own functions to C library, so, the programming task becomes simple, C language is the structured programming language. Due to the use of IC (Integrated Circuits), AC is required in many cases.

Fifth generation computers are in developmental stage which is based on the artificial intelligence.The goal of the fifth generation is to develop the device which could respond to natural language input and are capable of learning and self-organization. The disadvantage of these computers is that the microprocessor design and fabrication is very complex and requires expensive … FORTRAN/LISP: Lack of knowledge about the direction of computing progress. So we can say that the fifth generation computers will have the power of human intelligence. Often, there is need to store and manipulate two-dimensional data structures such as matrices and tables. Examples of fifth generation language include Mercury, OPS5, and Prolog. The use of parallel processing and supercomputers is helping to make artificial intelligence a reality. FORTRAN is still useful, but its domain is limited to what is now one of the smallest application spaces: very high performance scientific computing. x Required long time to convert into machine code. The serial numbers indicate the capability of computer and speed as well. Wrapping it … Large Scale Integration (LSI) and very large scale integration (VLSI), allows memory chips having thousands of storage locations. 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. Less repairement time and maintenance cost. Graphics User Interface (GUI) technology was exploited to offer more comfort to users. 1. The first two generations are called low level languages. No cooling system required in many cases of the fourth-generation computer. In San Francisco, over 50% of the families who are looking for a nanny want to hire someone who is fluent in a language other than their own – and that doesn’t always mean it is Spanish. The term fourth generation language is used to describe a variety of programming languages that are more non-procedural and conversational that prior languages. A fourth-generation programming language (4GL) is any computer programming language that belongs to a class of languages envisioned as an advancement upon third-generation programming languages (3GL). the major disadvantage of 5th generation is that are complex,sophicated tools for better programming . The fourth-generation programming language was used from 1970–1990. A fourth generation (programming) language (4GL) is a grouping of programming languages that attempt to get closer than 3GLs to human language, form of thinking and conceptualization. Third-generation languages use high-level language statements that are converted by a compiler into specific programming language statements. End user can often develop their own applications. Portable and cheaper than the older versions. The major advantages of fifth generation programming languages are that these languages are improved from fourth generation languages.
