Work Environment:
Network administrators usually work in IT departments or data centers, focusing on network reliability and upgrades. IT support specialists may work at help desks, offer remote assistance, or provide on-site technical help.

Responsiveness:
IT support professionals handle user issues quickly to minimize downtime. Network administrators focus on proactive maintenance, updates, and long-term network stability.
