Computer Network Topology Outline
The first thing that has to study about a network is its physical shape or design layout. It will be extremely important when a wiring scheme and design are selected for a new network installation. Actually Network Topology refers to physical shape or design layout of a network. Network topology determines how different nodes in a network are connected and how these nodes communicate to each other. Types of Computer Network Topology Network really has two shapes or two types of topology. Physical topology Logical topology Physical Topologies The physical topology is the physical shape or layout of the wires that can be visible in a network. The Physical topology defines how devices are interconnected with or without wires. Physical topology is further divided into two sections. Point-to-point connections Multipoint connections Point-to-point connections In a point-to-point connection, a communication link is established between two devices with one wire or air (in the case of wireless). A simple example of point-to- point connection is talking over telephone between two persons where anyone else is not allowed to use the phone on either side.
