Frequently asked questions about Network Administrators


What is the difference between a Network Administrator and a Network Engineer?

The difference between a Network Administrator and a Network Engineer is seniority and areas of job focus. For example, Network Engineers actually design computer network systems for an organization. They also create updates or add-ons to the original system to streamline business initiatives. In contrast, Network Administrators are responsible for monitoring a computer network after its creation. They make repairs, ensure security and assist company employees.

Both Network Engineers and Network Administrators need to have a bachelor’s degree in computer system management, information technology or computer programming. However, Network Engineers take on a more senior role when compared to Network Administrators because they need a few years of work experience as an Administrator before they can become an Engineer. Network Administrators and Network Engineers work closely together to identify problems and refine networks to meet business needs.

On a typical day, a Network Administrator starts by checking their email and voicemail to respond to time-sensitive messages from company employees or IT personnel.
