Using allegory can be a rather simple way to invent pseudoscience that is still governed by certain fundamental laws. Anything can be used as a base; then - through the continued use of synonyms - later mutated into something that fits the bill of what you are trying to say.
New York City can be broken down into; Lower Manhattan, Upper Manhattan, The Bronx, Brooklyn, and Queens. "New York City" is the inspiration for my invented tech device for present purposes.
It is located within a System (Nation), represents a network of metropolitan zones, and is commonly known for its core (The City Itself). Thus, I am going to call my device the "System Network Core" (SYNC). Next, I'll think up an allegorical name for each of the city's main boroughs, make them components, and move forward from there:
SYNCs possess 5 Power and Communication (PAC) Channels which interface each of its primary operating systems (POS). POS-1 is a data processor (Lower Manhattan); POS-2 is a matter converter (Upper Manhattan), and POS-1, 2, and 3 serve in a data storage capacity (Residential Zones).
The SYNC device is fueled in part by airborne energy particles (Airplanes) which are collected through three primary reciever units (Airports) and secondarily through solid power couplings (Freeways) which connect it to secondary hubs. SYNCS is an imbedded non-mobile device native aboard all C1 Starships...
...well, heck - I could go on forever writing loot like that. Whenever I want more details, I just go back to the model of New York, pull some real fact out of the hat, give it a symbolic title, and voilà. As fake as it is, since it is based allegorically off of something that is real in some fashion, it naturally retains at least a residue of coherency.
