Why choose Open Source software?
When choosing an open source product, it has advantages for the user, not only will always be available for free, as can be improved by any programmer. An Open Source program can be changed and improved because they can have access to the entire source code, any user can make suggestions or report errors, and programmers are always open to feedback, is a software made by all and for all, even creating communities dedicated to the improvement of certain programs, this benefits all.
Here I present a list of software with various categories and operating systems, which you can purchase for use as an alternative to commercial products, that not everyone can afford. The quality is not always equivalent to the commercial product, but in most cases it is sufficient for the needs of the user, or to the novice user start to learn how it works.
