What does the system administrator do freely?

Free system administrators are responsible for the design, installation, configuration, management and maintenance of network devices and server systems.

Free system administrators play an important role in the whole network. They are responsible for designing network architecture, selecting appropriate network equipment and servers, and installing and configuring them. They are also responsible for monitoring and managing the running state of the network to ensure the stability and reliability of the network. In addition, the system administrator is also responsible for formulating and implementing network security policies, including firewall settings, intrusion detection and preventive measures to protect the safe operation of the intranet. They will also regularly carry out system maintenance and upgrade to ensure the normal operation of network equipment and servers. Through these works, the free system administrator provides technical support for the safe operation of the intranet.
