There are many ways to set up a computer network

What are some types of networks you’ve learned about so far?Slide3

Topology is the study of how things are arranged

Have you ever thought about how your classroom is arranged? Why are desks and tables placed where they are? Is the topology different from what you see in this Japanese classroom?

Topology refers to how things relate to each other in space—how they are organized.Network topology refers to the layout of devices that are connected on a computer network.

Bus topology has a central cable

A ring topology is a closed loop

A star LAN has a hub and many spokes

In a mesh LAN, devices can be fully or partially connected

A fully connected mesh LANA partially connected mesh LANSlide8

A tree LAN is also called a hierarchical network A tree LANSlide9

The topologies of WANs are not so easily definedBecause wide area networks (WANs) cover a large geographic area, it is difficult to define the topology.

In this diagram, the linked machines could be in the same building, in different buildings, or even in different countries.Slide10

Cables connect devices in a networkPartially stripped Ethernet cable showing the twisted wire pairsNetwork components are most often connected using cables.

An Ethernet cable, shown here, is the most common type of network cable.Slide11

All networks help users share resourcesAll network topologies have a common goal: to enable users to share resources and data.

Which network topology type would you use at home? At

school? In an office?
