What Does Logical Network Mean?
A logical network is a virtual representation of a network that appears to the user as an entirely separate and self-contained network even though it might physically be only a portion of a larger network or a local area network. It might also be an entity that has been created out of multiple separate networks and made to appear as a single network. This is often used in virtual environments where there are physical and virtual networks running together; so, out of convenience and function, separate networks can be made into a single logical network.
Techopedia Explains Logical Network
A logical network, unlike a physical network, often spans multiple physical devices such as network nodes and networking equipment that are often parts of separate physical networks. Or it can encompass only small sections of a single device. So, for example, a logical network can be made up of elements from separate networks with devices located around the globe as in a global enterprise where the computers of site managers from different countries might be connected as a single logical network in order to foster quick and hassle-free communication even though they are separated by continents. Or in the smallest virtual level, a logical network could be composed of several virtual machines and virtual networking entities, all of which reside in a single physical server. So, if there is a powerful physical server that could house 100 virtual machines and virtual networking equipment, it could theoretically have 10 or more logical networks within that single physical server.
