13 Facts About Network topology

Network topology can be used to define or describe the arrangement of various types of telecommunication networks, including command and control radio networks, industrial fieldbusses and computer networks.

In contrast, logical topology is the way that the signals act on the network media, or the way that the data passes through the network from one device to the next without regard to the physical interconnection of the devices.

Token Ring is a logical ring Network topology, but is wired as a physical star from the media access unit.

Network topology nodes are the points of connection of the transmission medium to transmitters and receivers of the electrical, optical, or radio signals carried in the medium.

Network topology bridge connects and filters traffic between two network segments at the data link layer of the OSI model to form a single network.

Network topology switch is a device that forwards and filters OSI layer 2 datagrams between ports based on the destination MAC address in each frame.

Study of network topology recognizes eight basic topologies: point-to-point, bus, star, ring or circular, mesh, tree, hybrid, or daisy chain.

Easiest to understand, of the variations of point-to-point Network topology, is a point-to-point communication channel that appears, to the user, to be permanently associated with the two endpoints.

Star Network topology is considered the easiest Network topology to design and implement.

The primary disadvantage of the star Network topology is that the hub represents a single point of failure.

Physical extended star topology in which repeaters are replaced with hubs or switches is a type of hybrid network topology and is referred to as a physical hierarchical star topology, although some texts make no distinction between the two topologies.

Fully connected network, complete topology, or full mesh topology is a network topology in which there is a direct link between all pairs of nodes.

Networks designed with this topology are usually very expensive to set up, but provide a high degree of reliability due to the multiple paths for data that are provided by the large number of redundant links between nodes.
