What is open-source software?
Open-source software is software that is distributed with its source code, is available for use, edit, and distributor under the license. Source code is a part of the software that most computer users don’t ever see.
The source code is released under a license by the developer of the software. This license is a basic set of guidelines on how you can access, modify, and redistribute the software. Programmers who have access to source code can change a program by adding to it, changing it, or fixing parts of it that aren’t working properly.
