19. Free Software
The freedom to deploy the software for any use
case without any restrictions
The freedom to study how the software works
and modify it according to your needs and
preferences.
The freedom to freely re-distribute the software

be done at a cost or at no cost.

21. Free redistribution of the software.
The source code should be publicly available.
The software can be modified and distributed in

28. A software repository is a storage location
where you can store software packages.
These software packages can be accessed
and installed, when required, on computers
in your network. Using
these repositories facilitates easy storage,
maintenance and backup
of software packages.
29. Software developers often maintain their own
repositories, from which software packages can
be downloaded and installed directly to our
computer. Though all application should be
included in the distribution software
repository, we can also download the third
party repositories.
30. There are more Linux web servers, but this list is
the most used web servers. The most used web
servers are Apache and Nginx.
