There are a few opportunities to work in network administrator roles with any degree background (ie a non-technical degree); however, this is unusual. Most network administrator jobs advertised ask for a computer science, software engineering or electronic engineering degree.
Network administrators need to understand how to connect devices to form a fast and efficient network.
