I'm also not an expert, but I would wager that networking doesn't change as fast as other computing-related topics because a big chunk of it is implemented in hardware, which is very expensive to change/upgrade, and that new network elements need to be compatible and integrated into existing networks, which don't easily change because its very expensice to change/upgrade and needs to remain compatible with other networking elements.
