Network administrators are fundamental to business operations and are responsible for ensuring network infrastructure is running smoothly and securely. As a network professional, your role would involve maintaining systems, programming computers, troubleshooting issues, and supporting users. You might also assist with IT networking design and planning – informing leadership of what hardware and software is needed, and then implementing the new technologies.
Career options exist within many different industries (almost every organisation has network needs), and there are a range of areas you could specialise in, such as support, security, systems, or wireless or cloud-based networks.

Network administrator FAQs
A computer network administrator job description involves managing and maintaining an organisation’s IT infrastructure. This includes:
- supporting and troubleshooting network issues and emergencies with specialist expertise
- installing, configuring, testing, maintaining, and managing new and upgraded networks, software applications, servers, and workstations
- developing network programs tailored to meet specific business needs and requirements creating and maintaining documentation for network inventory, recording diagnoses, resolving network faults, and detailing enhancements, modifications, and maintenance procedures.
While both roles are critical to IT infrastructure, there are key distinctions.
A network administrator focuses on day-to-day operations, ensuring the smooth functioning of networks. On the other hand, a network engineer designs and implements network systems and often works on larger-scale projects.
Understanding the difference between a network and a system administrator is equally important. System administrators manage broader IT systems, including servers and software, while network administrators specialise in connectivity and communication systems.
