Topology: The Design Or Shape In Which Nodes Are Connected On A Network.

Node: Any Computer Or Device That Is Connected To A Network.

Packet: A Message That Is Sent Over The Network From One Computer To Another

Switch: Central Connection Point Of A Network

Mesh TopologyTree TopologyHybrid TopologyDaisy chain Topology

Topologies

In Point-to-point topology two nodes are directly connect together.

Topologies (PtP)

In Point-to-point topology two nodes are directly connect together.

Like A Marriage. The Man Is Connected Directly To The Woman

Only Thing Nodes Are Smarter Because They Don’t Say “’Till Death Do Us Part”

Topologies (PtP)

Computers Are Strung Together In A Line.The Entire Network Is A Single Cable With

Each Node Tapping Into The Cable So As To Listen In On The Packet Being Sent.

If One Connection Is Broken…The Entire Network Crashes

Topologies (Bus)

Similar To The Ring Topology With An Exception

The Computers Are Connected In A Loop

Topologies (Ring)

Ring Topology is very orderlyPerforms well under heavy network loadDoesn’t Require A Central

Managing Sys.

Topologies (Ring)

However, A Disconnection with one computer affects the entire network

Topologies (Ring)

Also Adding Or Removing A Computer

Also Adding Or Removing A Computer… Affects The Network

Another Improvement… Is That Packets Are Sent Directly To The Necessary Node Rather Than Through Each Node

On The Flip Side, The Fact That Every Thing Is Connected To The Switch Means That…

Als0, These Networks Are Very Expensive To Set Up

And A Lot Of Wires Are Used In The Progress

Mesh Sponged Off Of Star Topology’s Idea Of Allowing The Network To Function Even Though One Computer Is Disconnected

In Mesh Topology, The Computers are connected directly To One Another

That Way A Broken Connection…

Topologies (Mesh)

That Way A Broken Connection… Doesn’t Seriously Affect The Network

That Way A Broken Connection… Doesn’t Seriously Affect The Network

Unless That’s The Gamers' Computer

Topologies (Mesh)

One Disadvantage Though Is That It Uses Quite A Lot Of Cables To Set Up The Network

Topologies (Mesh)

Tree Topology Are The Computers That Marry And Give Birth To Little Computers.

Ok Scratch That

Topologies (Tree)

Tree Topology Is The Order In Which Computers Rule Over Humans

Topologies (Tree)

Well Not Humans But Its Where Computers Are Arranged In An Hierarchy.

Some Computers Are Superior To Some possessing software that the others don’t

Hybrid topology is a computer network that uses a combination of two or more topologies.

It May Be bus, star, ring, and a ton well a few others.

Topologies (Hybrid)

Benefits of using a hybrid topology include being able to combine the best parts of the standard topologies.

The Down side may be an insane amount of Cables

Or Like Shad Said “BackBone”

Topologies (Hybrid)

ONCE AGAINThe easiest way to add more computers into a

network is by daisy-chaining

Topologies (Daisy Chain)

Not This one.

Topologies (Daisy Chain)

This one.

Topologies (Daisy Chain)

Its connecting each computer in series to the next.

If a message is intended for a computer partway down the line, each system bounces it along in sequence until it reaches the destination.
