HISTORY OF SOFTWARE

INTRODUCTION TO SOFTWARE ENGINEERING

In today's life software has become an integral part of almost all applications involving computer-based systems. It may be in the area of education, healthcare, finance, sports, recreation, science, research, marketing, entertainment, or any type of business or government-related operations, all automated applications in these areas presently include software. So designing and developing simple software is a very tedious and time-consuming job.

HISTORY OF SOFTWARE ENGINEERING

1. 1940s: First computer users wrote machine code by hand.

2. 1950s: Early tools, such as macro assemblers and interpreters were created and widely used to improve productivity and quality. First-generation optimizing compilers.

3. 1960s: Second-generation tools like optimizing compilers and inspection were being used to improve productivity and quality. The concept of software engineering was widely discussed. First really big (100 programmers) projects. Commercial mainframes and custom software for big business.

4. 1970s: Collaborative software tools, such as UNIX, code repositories, make, and so on. Minicomputers and the rise of small business software.

5. 1980s: Personal computers and workstations and an emphasis on processes like the CMM. The rise of consumer software.

6. 1990s: Object-oriented programming and agile processes like Extreme programming that gain mainstream acceptance in software engineering. The WWW and hand-held computers make the software even more widely available.

7. 2000s: Managed and interpreted platforms such as .Net, PHP, and Java make writing software easier than ever before.
