But speed is not the only thing that has been thought about, NX also provides a secure service since all information travels through SSH. The speed of the NX service is due to the compression and caching performed by the X11 protocol, which minimizes the amount of information transferred between client and server.

NX is a technology that allows remote X11 sessions to be executed quickly and with excellent graphic quality, it was developed by the French company NoMachine, which offers client and server applications for free (but not free) and also commercially. Well, simple, from any PC from the house you access your user account that is in the computer that your brother is using at that moment and voila, you have your session with everything and what you have in it as if you were in front of the server and working, great right? Well, NX technology allows this and much more.

Imagine that at home you want to use your computer but your younger brother is checking his social networks and you need to do a task, to top it all, the file you need is on that 'very busy' computer.
