CASE STUDY;A compiler uses a language translation program that converts the entire source program into object code, known as an object module, at one time. The object module is stored and it is the module that executes when the program runs. The program does not have to be compiled again until changes are made in the source code. Software trends and issues Open source software coming to the scene: This is software that is freely available to anyone and can be easily modified. The use of open source software has increased dramatically due to the World Wide Web. Users can download the source code from web sites. Open source software is often more reliable than commercial software because there are many users collaborating to fix problems. The biggest problem with open source software is the lack of formal technical support. However, some companies that package open source software with various add-ons and sell it with support are addressing this. An example of this is Red Hat Linux operating system.
