Anything to this:
..... the realities of the Triple 777, in it has TRIPLE REDUNDANCY or there are three systems for each system on that aircraft in case the first one is inoperative.

[Cboldt]

My guess is that any triple redundancy is limited to safty critical functions (flight control surfaces, primarily), and that many systems are not redundant at all (in-flight entertainment).

The powerplants aren't triple redundant, there are two engines. The aircraft can fly with one.

The triple redundncy relates to the fly-by-wire system:

The flight control system for the Boeing 777 airplane is a Fly-By-Wire (FBW) system. The FBW system must meet extremely high levels of functional integrity and availability. The heart of the FBW concept is the use of triple redundancy for all hardware resources: computing system, airplane electrical power, hydraulic power and communication path. The Primary Flight Computer (PFC) is the central computation element of the FBW system. The triple modular redundancy (TMR) concept also applies to the PFC architectural design. Further, the N-version dissimilarity issue is integrated to the TMR concept. The PFCs consist of three similar channels (of the same part number), and each channel contains three dissimilar computation lanes. The 777 program design is to select the ARINC 629 bus as the communication media for the FBW

Design Considerations in Boeing 777 Fly-By-Wire, is, I think, the full article. Geeky content; but interesting in that the triple redundancy is sometimes used to justify flying with one of the redundant systems being out of order. Allowing flight without all (redundant) systems in working order is by design intent. "Deferred maintenance."
