That's one of the things introduced in both books. In Titanicus , the Noosphere is a standard way of sending and interacting with information. In Mechanicum , it's still something new to the Mechanicum (as they referred to themselves at the time), the product of one of the forge-cities, and only starting to spread to a couple of others when the Heresy reaches Mars.
The other technology referred to frequently - again, for machine interface and communication - is Haptic s, which are essentially an advanced form of feedback system, providing a physical response to otherwise wireless interactions (common in Titans - it's long been described that the Princeps of a Titan 'feels' impacts against his Engine's armour, this is how. It's apparently a lot more widespread than that, however).
And, given the number of Tech-Priests present in both books, it does present a range of characterisations for them...
