A network topology is physical layout of the network i.e. the way in which the PCs are connected to each other.

At home PC networking, topology refers to the outline of connected plans.

Network topology is defined as the substantial interconnection of the various elements (links, nodes, and all that.) of a PC set of connections. Network Topologies can be substantial or commonsensical. Physical Topology wealth the substantial design of a set of connections as well as the plans, location and cable installation. Logical topology refers to the piece of information to how data essentially transfers in a set of connections as contrasting to its substantial design.

Topology can be considered as a virtual structure or arrangement of a set of connections. This structure essentially does not correspond to the tangible substantial design of the plans on the PC set of connections. The computers on the family circle set of connections can be arranged in a fly in a circle structure but it does not necessarily mean to it presents a ring topology.

Any instance set of connections topology is firm lone by the graphical mapping of the configuration of substantial and/or commonsensical contacts amid nodes. The study of set of connections topology uses graph theory. Distances amid nodes, substantial interconnections, transmission toll, and/or show types may possibly fail to agree in two networks and yet their topologies may possibly be identical.

A Local Area Network (LAN) is individual pattern of a set of connections to exhibits both a substantial topology and a commonsensical topology. Any set node in the LAN has individual or more family to individual or more nodes in the set of connections and the mapping of these family and nodes in a graph results in a geometrical structure to may possibly be used to portray the substantial topology of the set of connections. Likewise, the mapping of the data gush amid the nodes in the set of connections determines the commonsensical topology of the set of connections. The substantial and commonsensical topologies may possibly or may possibly not be identical in some instance set of connections.

There are 3 basic topologies viz: Bus, Star and Ring. And other 2 are Hybrid topologies viz: Tree and Mesh.
