Open source software is any kind of program that anyone in the world can download, modify, and distribute without paying any fees. This is because the developer has specifically chosen to release the source code for free under an open source license
Open source software has become increasingly popular over the years and is used in everything from networking to web servers.
It’s important to remember that open source doesn’t just mean “free.” Many companies release their software for free, but retain full copyright to their code, so other developers can’t modify it.
Successful open source initiatives, on the other hand, are built on the hard work of potentially thousands of employees who have voluntarily given up their time to create something great. Such an accessible development methodology has a number of serious advantages. Open source software is often more secure because people from all over the world scrutinize new releases and bugs are reported and addressed quickly. Also, people are motivated to add interesting new features to open source platforms, which means that open source software is often just as good, if not better, than competing closed source software programs
