The Net is everything. In the galaxy electronic systems and information are linked in one grand system that exists everywhere. where there is a computer there is the Net and everything that comes with it.
The Exo Net is the generic webspace that is beamed back and forth across the galaxy. It has some of the highest security protocols but the vast majority of all information.
The Extra Net is the name given to any system that is specific to a location, planet or zone it has outlets and gates to the Exo Net, and receives regular updates from the main system.
Since AI’s live in the net, the Net has been policed by USMC sanctioned AI’s, and Firewalls partition segments of the Exo and Extra Nets to prevent AI’s from controlling the entire system.
