FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -4GLs are sometimes called problem-oriented languages or non-procedural languages, and require less training than 3GLs. In these languages one tells the computer what to do, not how to do it. Programmers and end-users use 4GLs to develop software applications.

Detailed explanation-2: -fourth-generation language (4GL), computer programming language that is intended to be easier for users than machine languages (first-generation), assembly languages (second-generation), and the older high-level languages (third-generation).

Detailed explanation-3: -Fourth Generation of computers was between 1971 – 1980. These computers used the VLSI technology or the Very Large Scale Integrated (VLSI) circuits technology. Therefore they were also known as the microprocessors. Intel was the first company to develop a microprocessor.

Detailed explanation-4: -Fourth-generation Programming Language: The Structured Query Language (SQL) is the dominance-specific language used in the programming of data that is held within the RDBMS or in an RRSMS system for stream processing. SQL is essentially a declarative language (4GL), it also includes procedural elements.

Detailed explanation-5: -The term fourth generation techniques (4GT) encompasses a broad array of software tools that have one thing in common: each enables the software engineer to specify some characteristic of software at a high level. The tool then automatically generates source code based on the developer’s specification.
