An end node is a peripheral unit in a network, or a primary designated unit within that network. IT professionals and others use the term "end node" to specify a certain hardware component of a network that has its own role and properties within that network system.
One general way to talk about an end node relates to comprehensive network security and the kinds of hardware interfaces that are used. IT pros may refer to certain computers that are provided for end users as end nodes, especially when they are seen as the end display point for a complicated network.
Experts might also discuss an "end node problem," which involves individual end nodes that may not be up to network security standards, and may make a network vulnerable.
The end node problem is particularly relevant in cloud computing, where end nodes may be part of the cloud network, but not actively managed by the cloud’s host. These network nodes may have problems related to improper software configuration, weak security and vulnerability to malware or viruses, or other security issues. In a very simple sense, the end node is often the weakest link that security and tech experts look at within the network.
