What is Open Source software?

[King Belieal]

I have seen so many discussions about open source software and closed source software. What is the difference between open source software and closed source software?

Which one do you think is better between open source software and closed source software?

From the little knowledge I have, open source software are those apps that the source codes are made public so that one can modify it as they want.
