Q. What do you mean by Software Engineering? What is the use of Software Engineering?
Ans) Software engineering is engineering for software development. A simple program can be written without using software engineering fundamentals. But if one needs to develop a large product, then software engineering principles are essential to achieve a good quality software cost effectively.
Without using software engineering fundamentals it could be difficult to develop large programs. In industry it is generally needed to develop large programs to accommodate multiple functions. A problem with developing such large commercial programs is that the difficulty and complexity levels of the programs increase exponentially with their sizes.
System evolution of life cycle process The lifetime of verge systems is too long. They must evolve to meet change requests. The evolution may be expensive. Existing sy
