A network administrator builds, maintains, and troubleshoots computer networks. Their role is to monitor a network and spot any errors that could damage its functionality.

You’ll find network administrators in almost every industry because most big companies use extensive computer networks to conduct their daily operations. A network administrator works with computer software and hardware, including firewalls, routers, and switchers.

What Does a Network Administrator Do?

A network administrator will have different responsibilities depending on the network size of the company they work for. However, some basic tasks include setting up a computer network, overseeing it, and developing protection strategies. Below are some details on these key duties.

Sets Up a Computer Network

Setting up a network involves installing hardware for a company. This might include routers, databases, and servers. However, not all administrators need to build networks. Some are only hired to maintain and troubleshoot existing networks.

Troubleshoots the Network

Errors can significantly damage a network, so troubleshooting potential problems is an essential part of network administration work. When troubleshooting, you will check the network’s hardware, perform DNS checks, and monitor malware. Sometimes, a network can fall victim to a virus or cyberattack. You will need to implement protection techniques.

Protects the Network

This is the process of preventing malicious or unauthorized access to a network. To do this, you will install firewalls and maintain anti-virus software. Protecting the network is especially important when there is sensitive information.

Network Administration Education Pathways

Network administrators must have a background in IT. This usually takes the form of a Bachelor’s Degree in Computer Science or Software Engineering. Read below to learn more about the education paths and degree programs you can take to become a network administrator.

Network Administrator Degrees

Network Administrator Bootcamps

A network administrator needs to have some software engineering skills. Although it is rare to find a bootcamp that offers a network administration course, you can instead join a software engineering program to get the skills you need.
