What is a Topology?

TOPOLOGIES AND NAVIGATION MAPS

This page explains LANs vs WANs, the client-server model, common network topologies, and navigation maps.

Layer 1

Network Types & Models

The different ways networks can be categorised and structured, including local and wide area networks and the client-server model that governs how devices communicate.

Topology

Topologies are often represented as a graph. Network topologies describe the arrangement of networks and the relative location of traffic flows.

LAN

A local area network connects devices within a small geographic area such as a home, school, or office.

WAN

A wide area network covers a large geographic area, often connecting multiple LANs, such as the Internet.

Client-Server Model

A network model where clients request assets from servers, which process and respond to those requests.

Network Topologies

The physical or logical arrangement of devices within a network, each offering different advantages in terms of speed, reliability, and scalability.

Bus Topology

A network topology where all devices are connected to a single central cable.

Star Topology

A network topology where all devices are connected to a central hub or switch, which manages data transmission.

Ring Topology

A network topology where each device is connected to two others, forming a circular pathway for data to travel.

Mesh Topology

A network topology where devices are interconnected with multiple paths, allowing data to take different routes for reliability.

Hybrid Topology

A network topology that combines two or more different topologies, such as star and bus, into one network.

Navigation Maps

Graphical representations that visually map out the structure and connections of a network, making it easier to understand and manage.

Navigation Map

A graphical representation of the structure and connections of a computer network.
