Network Administrator

What Do Network Administrators Do?

Network administrators act as the chief operating officers of computer networks. They play a pivotal role within companies and organizations, handling day-to-day operations while monitoring both local area networks and wide area networks and their related equipment.

Organizations rely on network administrators to safeguard their data network. Additionally, professionals install firewalls, evaluate software and hardware, monitor traffic, install filters and test the network for weaknesses.

Depending on the size of the organization they work for, network administrators have slightly different responsibilities. Administrators in a small, start-up environment often have an array of duties, and may play a significant role in shaping the size and structure of their company’s network. Larger networks may have multiple administrators, where individual workers are only responsible for overseeing part of a much larger system.

Network administrators generally work full-time and are often on-call, along with network architects and other IT staff. Due to their specialized knowledge of company-specific network systems, their skills are required when technical problems arise. Consequently, they often work late.

Key Skills

  • SQL (Structured Query Language)
  • System Administration
  • Microsoft Active Directory database
  • Know-how to build an organization’s networking system from scratch
  • Ability to maintain internal and external communications, data storage and server systems
  • Well-versed in troubleshooting server problems

As important as any technical skill, network administrators must be adaptable and creative. They often need to supply imaginative solutions to technical problems and sometimes have to troubleshoot quickly. Network administrators must also stay up to date on new software and networking programs while ensuring that the existing network’s capabilities are sufficient for their company. In short, the best network administrators combine a wide breadth of technical knowledge with a flexible, helpful and inquisitive mentality.
