Network Administration

Field Overview

Network Administration is a vital hands-on IT discipline centered on the daily operational setup, hardware configuration, management, maintenance, and systematic troubleshooting of an organization's local area networks (LANs), wide area networks (WANs), wireless systems, and internet connectivity. Network administrators ensure that employees, servers, and devices remain connected with maximum uptime and minimal latency.

Students gain extensive practical experience configuring physical routers, layer 2/3 switches, hardware firewalls, wireless access points, and server connection racks. Learning resources provided by the Cisco Learning Network and certification roadmaps maintained by CompTIA Network+ form the core of study in this practical major.

What You Will Learn

• Router & Switch Configuration: Hands-on command-line setup (CLI) of enterprise Cisco, Juniper, and MikroTik routers and managed switches.
• IP Addressing & Subnetting: Designing IPv4 and IPv6 addressing schemes, Variable Length Subnet Masking (VLSM), and NAT translation rules.
• Network Infrastructure Services: Setting up and managing Domain Name System (DNS), Dynamic Host Configuration Protocol (DHCP), and Active Directory domain controllers.
• Wireless Network Deployment: Designing, installing, securing, and optimizing enterprise Wi-Fi 6 networks and point-to-point wireless links.
• Diagnostics & Uptime Monitoring: Utilizing network monitoring tools (SolarWinds, Wireshark, PRTG) to identify packet loss, bandwidth bottlenecks, and hardware faults.

Career & Industry Outlook

Every business office, university campus, hospital facility, municipal agency, and call center relies on network administrators to manage physical and wireless connectivity.

Graduates obtain stable, well-compensated positions as network administrators, network support engineers, systems administrators, IT infrastructure technicians, and network operation center (NOC) analysts.

Is This Field Right for You?

This major is perfect for pragmatic, systematic problem-solvers who enjoy working directly with networking hardware, physical cabling racks, server rooms, and device configurations. If you take pride in establishing rock-solid connections and diagnosing technical hardware issues, Network Administration is a natural fit.
