Network Administrator Job Description and Overview

As technology evolves to suit different environments, situations, and industry needs, network administrator’s roles must evolve as well. For example, as more professionals work from home, network administrators must take on all new tasks and responsibilities focused on securing data remotely.

Network administration is dynamic and unpredictable, and professionals in this field handle different tasks and varied issues every day. Earning a Bachelor of Science in Information and Cybersecurity Technology can prepare aspiring network administrators to provide essential services that evolve alongside technology, helping companies, industries, and society at large move forward into the future.

What Is a Network Administrator?

In every type of organization, from hospitals and banks to government agencies and airlines, computers are always communicating with each other across networks. Network administrators are responsible for installing, managing, and operating these networks in ways that facilitate smooth, reliable communication.

These individuals must understand how networks work, be familiar with a wide range of server types and configurations, and have deep knowledge of network security to perform well in their roles.

Network Administrator Job Description and Duties

No two network administrator job descriptions are exactly the same, because every organization and industry has a unique set of challenges and needs. Network administrators provide services designed to ensure that their organization’s computer networks run efficiently. Network administrators’ essential responsibilities include the following:

• Hardware Configuration: Network administrators install and configure servers, routers, switches, and other types of computer hardware essential to an organization’s network.
• Maintenance and Repairs: Networks and systems often need upgrades, troubleshooting, and repairs to support efficient communication
• Network Design: In some cases, network administrators serve as or work with network architects to design networks and databases.
• Software Management: Administrators manage and maintain all the software an organization uses, including email, video conferencing, productivity, and proprietary software.
• Network Security Management: Many network administrators serve as cybersecurity professionals, using a wide range of security measures to maintain data integrity and network safety.
• Network Storage Optimization: Many modern organizations rely on a variety of cloud-based and on-site storage options. Administrators are responsible for ensuring the storage sites are adequate and well-protected.
• Systems Installation: Depending on the organization’s needs, a network administrator may install and manage intranets, the internet, local area networks (LANs), wide area networks (WANs), and other systems.
• System Performance Checks: Administrators regularly conduct performance evaluations to reduce errors and ensure that the existing networks meet the organization’s needs.
• Network Address Assignment: Network administrators assign static or dynamic IP addresses to devices on networks.
• Routing Protocol Assignment: Administrators determine how routers connect and communicate with one another on an organization-wide basis.
• Device Updates: Administrators oversee the devices connected to networks, including computers, printers, routers, and smartphones, updating their associated drivers regularly to ensure their proper authentication and function.
• Server Maintenance: Some network administrators monitor server performance, including intrusion detection systems.

Network Administrator Salary and Job Outlook

The number of jobs for network administrators is on the rise, according to the U.S. Bureau of Labor Statistics (BLS), which projects 2% employment growth between 2022 and 2032. Roughly 19,800 job openings are expected to be available each year during that period. As technology continues to evolve, the need for skilled network administration professionals will grow.

The BLS reports that the median annual salary for network and computer systems administrators was $95,360 as of May 2023. Those working in the information and management sectors earn more on average, while those working in educational services earn less.

How to Become a Network Administrator

Although many paths can lead to a career in network administration, given the rate at which modern technology evolves, a certain level of education, work experience, skills, and credentials are required to qualify for the role. The following steps can help aspiring network administrators find the right position.

Earn a Degree

Although some entry-level positions may be available to high school graduates or individuals with information technology certificates, most employers seek baccalaureate-educated candidates to fill open roles. A bachelor’s degree in information technology, computer science, systems engineering, or a related field is preferred.

Gain Work Experience

Experience is important for job stability and higher salaries. Hands-on experience provides network administrators with the opportunity to practice their soft skills like communication and problem-solving which can boost their resumes. Internships, junior roles, and apprenticeships can provide experience. Many network administrators start their careers by answering phones and emails at a help desk.

Hone Key Skills

Some of the key technical skills and expertise required to be a successful network administrator are coding language knowledge, network and server familiarity, and the ability to use diagnostic software. Beneficial soft skills include communication, organization, multitasking, and critical thinking skills.
