What is the difference between open source software and closed source software?
What are open source programs and closed source programs? In this post I will answer some of the questions that concern some and the majority of beginners in the field of technology and the field of information.

We will know them separately.

But in the beginning, everyone knows that every existing application or program has been built and developed by the programmers, isn't it, by a well-known programming language, after the programmer has finished building a program and made it operational? He raises a program or application that is on a date with two options that either Makes it open source or closed source.

What are open source programs?

It is the software that can view and amend its programming code, and it is more flexible to the user than other programs that do not provide flexibility to the user and cannot be modified, which some call a proprietary software ..

Open source software is often free and sometimes for a fee. This is a simplified expression of the idea of ​​open source software.

What are closed source programs?

It is the program that has the rights or publication under the EULA license and when the project owner uses technical methods to prevent users from modifying his program such as not publishing the source code of the program. Or when this person uses legal methods such as copyrights and EULA licenses to prevent the user from redistributing the program to other users. Reverse open source software where the user can use, modify, study and redistribute the program.

Examples of open source and closed source software.

Open source. Programming languages ​​{python-Java-PHP-Perl-Ruby} Operating system {Ubuntu-feedora-Debian-RedHat}

Closed source. Programming languages ​​{C # -Asp.net-Mysql} Operating system {Mac-windows}
