Network Administrator and System Administrator are the two terms that overlap each other but in reality, they are very different from each other. In this blog, we will discuss what the roles of network administrators and system administrators are and how they differ from each other.
The main responsibilities of the network administrator are to install, configure and support the local area network (LAN), wide area network (WAN), segment f a network system or internet system of an organization. It’s like a network administrator builds and maintains the road through which the system communicates.
The basic roles of the network administrator are as follows:

- Configure/rack/test network equipment: It is the duty of the network administrator to deploy the equipment from the box to the rack. It is not that easy as a lot of planning is required before deploying the network. Planning revolves around IP space, access control, network segmentation, routing, network segregation, etc.
- Network Maintenance: Network equipment requires regular maintenance for patching & updates. It is the responsibility of network administrators to maintain these pieces of equipment for regular updates and he or she maintains the schedule of the window maintenance.
- Network Monitoring: Monitoring of the network is the biggest duty of a network administrator. A network admin knows the potential of a network outage and he or she can do this by using different software that is installed on the server. It is monitored through network devices via SNMP protocol.
- Network Troubleshooting: Whenever any problem occurs on a network, the network administrator finds the issue and troubleshoots it. In a network, continuous changes are made, out of which some changes fix one problem and create another issue. It is the network administrator’s job to find the root cause and solve the cause by implementing a potential solution.
- Cabling: Cables are used to connect devices in a network and the communication took place via cabling only. A network administrator is responsible for cabling.

The maintenance of the window should be done on the weekends or at late night so that it should not impact the working of the business.
