Computer Software

Fourth-Generation Languages

• Fourth-generation computer languages emerged in the late 1970s, and their development is still in progress.
• These languages dramatically reduce programming time and
• make software tasks easy so that nontechnical computer users can develop applications without the help of professional programmers.
• Fourth-generation tools also include prewritten application software packages that can be used directly by end users.
• For instance, using the software package Lotus 1-2-3, users can create their own financial spreadsheets and manipulate data without knowing any programming.
