Network mapping

Is the process of making a visual representation of network devices and their interconnections. It can also be referred as the study of the physical connectivity of networks. Network maps help administrators spot network hitches, drill down to the problematic device/link, and start the remediation process.

Network monitoring

Is the process of constantly monitoring the computer networks and alerting the network administrator (via email, SMS or other alarms) in case of any network outages. The network monitoring tool also helps to identify faulty network devices and critical security issues.
