WIRED NETWORK TOPOLOGY (OBJ 1.6)

Network Topology

Refers to the arrangement of different elements like links,nodes,clients and servers that make up a computer network

Physical Topology

Used to show how the network devices and components are physically cabled and connected together

•Focused on the physical layout of the cabling devices

Logical Topology

Talks about how the traffic is actually going to flow in the network

•focused on the logical or network flow of the data

Point to Point Topology

Simplest form of network topology that involves a direct connection between two devices

Ring Topology

Network configuration where each device is connected to two other devices forming a circular data path

FDDI

Fiber Distributed Data Interface

Fiber Distributed Data Interface (FDDI)

Used to conduct data transmissions on fiber optic lines in a LAN

Up to 200km

Bus Topology

All of the network devices are connected to a single central cable called the “bus” or the “backbone”

Star Topology

One of the most common network layouts that is in use today

• each node in the network is going to be connected to a centralized connection point

Hub and Spoke Topology

Variation of star topology where the central node (hub) is connected to multiple nodes (spokes)

Mesh Topology

Features a point to point connection between every single device on the network to create a robust and redundant network

Partial Mesh Topology

Some nodes are organized in a full mesh scheme while others are only connected to one or two devices in the network

Number of Connections Equation

X=n (n-1) /2

n=number of nodes
