What is a network administrator?
A network administrator focuses on the day-to-day management and maintenance of existing networks, ensuring their optimal performance, security, and availability. Their responsibilities include:
- Monitoring network performance
- Troubleshooting connectivity issues
- Managing user access
- Implementing network policies and procedures
- Managing backup systems for the network
Depending on the organization's size, network administrators might be responsible for supporting desktop computers and other networked devices. They must thoroughly understand switches, routers, and networked communications. Network administrators ensure the smooth operation of the network and address any problems that arise.
