You might not guess this from looking at job postings, but network administration and systems administration are separate specialties within IT.

It gets confusing because the two functions are closely related and are often combined, especially in smaller organizations. The job title alone isn’t enough to go on; you need to read the description carefully to understand exactly what’s involved.

So what is the difference between a network and systems administrator?

The short answer is that a network administrator manages the actual network, while a systems administrator maintains the systems on the network (servers, desktop/laptop computers, and applications).

The two roles do share some similarities, however.

In this post, we explain how network administrators and systems administrators compare in terms of job tasks, skills, salaries, and training paths.

Here’s what you need to know.

When Kris Wattie was finishing high school, he didn’t really know what he wanted to do with his life.

He did know that he enjoyed gaming. He got very involved in the gaming community, and a game server owner gave him a chance to start learning about the administration aspect.

That inspired him to pursue a career in network administration. But first he needed some quality training.

Kris looked around for a course that reflected his learning style. He wanted a program that would let him explore one topic fully before moving on to the next.

He found it in the computer networking technology program at Herzing College.

Kris successfully completed the program—and landed a job as an IT administrator at Novotech!

We caught up with him recently to get his take on the course, the staff, and his experiences during training. Here’s his story.
