Study Notes
Objectives
- Explain the different types of network topologies.
- Describe the different types of network cabling and connectors.
- Describe the IEEE networking standards.
Introduction
- Every network provides a method of getting data from one system to another with either cabling or wireless methods.
- Standards ensure networking equipment works well together.
Overview of Network Topologies
- Network topology refers to the methods of connecting computers together.
- Historical topologies include bus, ring, and star.
- Modern topologies include hybrid, mesh, point-to-multipoint, and point-to-point.
Bus and Ring Topologies
- Bus topology uses a single bus cable and connects all computers in a line.
- Data flows from each computer onto the bus in a bus topology.
- Termination is required at the ends of a bus topology to prevent signal reflection.
- Ring topology uses a central ring of cable and connects all computers in a ring on the network.
- In a ring topology, data flows from one computer to the next in a circle.
- There is no end of cable and no need for termination in a ring topology.
- A broken cable in bus and ring topologies result in the entire network stopping.
Star Topology
- Star topology has one central connection for all computers.
- Star topology has fault tolerance - meaning if one cable breaks, other computers can still communicate.
- Star topology was not successful early on because it was more expensive than bus and ring topologies and difficult to redesign early bus and ring hardware.
Hybrid Topology
- Hybrid topology combines topologies, such as star-ring or star-bus.
- Star-bus topology eventually won out over star-ring.
- Physical topology describes how cables physically look.
- Logical (signaling) topology refers to how signals travel electronically.
Wireless Network Topologies
- Mesh topology means every computer connects to every other computer via two or more routes.
- Partially meshed topology involves at least two machines having redundant connections.
- Fully meshed topology means every computer directly connects to every other computer.
Parameters of a Topology
- Topology is only one feature of a network.
- Other network features include cable composition, cable length, and how machines decide when to send data.
