Networking is extremely dense and extremely hard.
Its also a space filled with professionals who do it for a job. Many on this sub are current or ex networking or security professionals who understand this shit like the back of their hand.
Im no idiot with IT - I’ve had pc’s my whole life and work in close proxiimity to IT. But networking, security and the clusterfuck of everything associated with it is honestly about as hard to get into as actuarial science.
It requires such a heavy base of fundamental concepts that if you dont start at the bottom and work up, you have no clue wtf is going on.

Unlikely to get rid of photos as Id have to digitize all the old stuff and physical copies are a pretty good backup…
