I've found folk that google (research) how-to's on YouTube are able to tackle jobs they otherwise would not.

Can you tell what a network technician does?

Here that work is all over the map from cable plant installation which in some states requires a certification and permits to just running around punching down wires and crimping on RJ-45 jacks. Others may have to fix home internet issues (Geek Squad does this millions of times a year) and then we have Cisco networking and then a whole other field in network security.
