Network administration is at the heart of every business network. Network administrators create, maintain, and troubleshoot internal systems that help a company be productive. Without a network administrator, the network would crash and desktops would no longer be able to communicate. Network administrators ensure the network runs smoothly, and each client computer is able to connect and perform daily tasks.

What Does a Network Administrator Do?

As the Internet becomes more popular for company productivity, network administrators are responsible for globally connecting multiple networks. They ensure that the network has the right hardware for performance, and they assist server administrators with configurations on the network. They maintain employee connectivity and help troubleshoot when desktops or mobile devices aren’t able to connect. They maintain data integrity by ensuring network stability. They also secure data and configure systems to protect against cyber threats. Network administrators usually work in a team unless they are responsible for a small local network. Network administrators oversee all aspects of the corporate system.

Network administrators have several daily tasks even if those tasks only require monitoring and reports for the day. They add new hardware when it’s needed, but they usually support and troubleshoot network issues. They update firmware and software for various network systems, so all security patches are installed.
