Network administrators are responsible for maintaining the network that a company relies on to conduct business. You take on the installation of new systems, regular maintenance checks and updates. You can also make recommendations for improved performance and security. Read on to find out more about this role and landing the job!
What is a network?
To understand what network administrators do, it is helpful to first understand the role of a network within an organization. A network is any series of connected devices. This can describe either local networks (LAN) or wide area networks (WAN).

LANs are widely used in organizations, but also schools, colleges, libraries, churches, community centers, and more. Computers on a LAN are usually connected via wired TCP / IP Ethernet or WLAN. Typically, all of these devices are then connected to a central hub (another computer or router). There is no limit to the number of users that can be added to a LAN. It is even possible to connect LANs across locations to create a larger “virtual LAN”.
A WAN is simply made up of several connected LANs. This enables remote collaboration and file sharing even in different countries. This is usually reserved for larger organizations because WANs are expensive to set up and maintain. The internet itself is an example of a WAN!
Why companies use networks
Why might a company choose to have a LAN instead of simply using the World Wide Web to communicate? The benefits are speed (especially with large file transfers), reliability, and security. Whether you’re sending a large media file to a colleague, exchanging highly sensitive customer data, or connecting to a printer in another room, LANs simply perform better. They also provide a single entry point for surveillance by a security specialist, making backups quick and easy.
Whether you’re sending a large media file to a colleague, exchanging highly sensitive customer data, or connecting to a printer in another room, LANs simply perform better.
Larger companies that want the same benefits in multiple locations can therefore invest in a WAN. For this purpose, they will lease a line between several locations that offers a fast and secure connection.
So that is the role of the network in an organization. But what do network administrators do to ensure that everything runs smoothly?
What do network administrators do?
The network administrator is responsible for managing and maintaining these systems. When a network stops working, the administrator needs to determine the source of the problem and get things working again. You should also take security measures to prevent recurrence.

An administrator can also help a new user to get set up on the system. They can take care of installing new hardware to improve speed, and they can run regular checks to make sure everything is working optimally.
Network administrator versus system administrator and other roles
The term “network administrator” can cover a wide range of different roles within an organization. What network administrators do on a daily basis depends on the type of company they work for.
For example, a network administrator working for a small organization may be required to oversee the initial design and installation of a new network. For larger companies, however, this task can be performed by a network architect.
Similarly, a network administrator can be asked to take on regular IT support roles within an organization. Here, the responsibility of the network administrator includes all systems connected to the network. In other organizations, this type of work can be done by a dedicated system administrator or IT support team. Administrators may also need to work closely with cybersecurity specialists in the event of a network breach.
Network administrators not only work with hardware, but also with software. Networks use a variety of “network services” to improve security, facilitate communication, and monitor usage. As a result, administrators have to install and maintain tools such as name services, email clients, firewalls, etc.
Network administrators don’t just work with hardware.
The size of the organization determines what network administrators do in other ways. For example, an administrator managing a large WAN requires more extensive knowledge than if he were only working with a few connected devices over a LAN.
For very large organizations, network administrators may need to perform server maintenance and even custom software tools that facilitate communication between remote team members.
Salary and Demand
If you like the sound of the network administrators, there is good news: this is a well-paid and highly sought-after role. According to the CIO, network administrators were among the 13 most sought-after roles in 2019.

This demand is expected to increase by up to 6% between 2016 and 2026. This is due to the increasing reliance on technology in various industries. However, it is also due to a number of seismic changes in the way business is done. After Covid, more companies than ever allow / require their teams to work remotely. As a result, network security is becoming more important than ever and is changing exactly what network administrators do every day. Administrators now have to face new challenges, such as the risks associated with using PCs.

Meanwhile, experts believe that the Internet of Things (IoT) will lead to an even greater need for fast and secure networks as more physical elements in the home and office are connected.
According to PayScale, the average salary for a network administrator is $ 59,906 per year.

This can provide opportunities for personal growth and possibly even additional qualifications and certificates.
Either way, for many IT professionals, becoming a network administrator is a very rewarding endeavor and a wise investment.
