Network attached storage or NAS is the file-level computer data storage connected to a computer network to provide data access to heterogeneous clients.
Is the process that administrators use to find/track down the devices present in a network. This helps gather information about the functional state of devices connected to the network. Network discovery tools help administrators manage very large and complex networks.
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.
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.
Refers to the process of examining the entire network for proper functioning of devices connected to it. It serves to uphold both the security and performance of a network. Network scanning may be employed from outside of any network to identify potential network vulnerabilities.
Refers to how various network components are arranged. Network topology varies between networks based on its use. It can be of either physical or logical. The way in which different nodes/links communicate with each other is determined by the topology of the network.
