PPT-NETWORK TOPOLOGIES Topology refers to the layout of the network i.e. the arrangement in

The characteristics of a network depend upon the type of topology selected for designing that network There are five basic network topologies 1 Star Topology 2 Ring Topology 3 Bus Topology.

Identify obvious strengths and weaknesses of these topologies. Objectives. Describe the basic and hybrid LAN physical topologies, and their uses, advantages and . disadvantages.. Describe the backbone structures that form the foundation for most LANs. Simple Physical Topologies. Routing – the path a message takes to get from one node to another.. Network connections can be static or dynamic (ex. Bus). Network Properties. Diameter – Maximum distance between nodes. Degree – maximum number of connections on a node. When working with a network. What is Physical Topology?????. The physical topology of a network refers to the configuration of cables, computers, and other peripherals. Physical topology should not be confused with logical topology which is the method used to pass information between workstations. .
