I have a project regarding the basics of application software, software ownership rights; commercial software,shareware,fireware, public domain software how it impacts in my field and Ethical or Legal Impacts in my field.
What you posted is quite vague. I think you've posted your assignment, but you haven't given specifics, so it's hard to help you. You haven't named any software applications, and you haven't stated what "my field" is.
So read widely in the search results I have linked at the top of my response. Take excellent notes about all aspects of your assignment. Then you'll undoubtedly need to conduct a search regarding your "field" -- possibly like this:
1. Go to http://www.google.com
2. Enter software ownership rights ethical legal effects ____________ (putting the name of your "field" in the blank).
Again, read widely and take good notes.
Let us know what you come up with.
