[Trisquel-users] Re : A virtual personal server?

[lcerf]

What you describe (several operating systems running "inside or alongside  
another") is virtualization. But one can simply run servers (a server is a  
program accepting incoming connections from the network, nothing more) on one  
single operating system, which can run desktop applications at the same time.  
For instance, if you install the "apache2" package then you have a Web server  
running on your computer.
