Transcript

  • 1. ECE 2225 Networking U.Kota
  • 2.  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
  • 3.  There Are 8 Basic Topologies That Virtually All Networks Follow.  Point to Point Topology  Bus Topology  Ring Topology  Star Topology
  • 4.  There Are 8 Basic Topologies That Virtually All Networks Follow.  Mesh Topology  Tree Topology  Hybrid Topology  Daisy chain Topology
  • 5.  In Point-to-point topology two nodes are directly connect together.
  • 6.  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”
  • 7.  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. • PC 1 • PC 2 • PC 3 • PC 4
  • 8. • PC 1 • PC 2 • PC 3 • PC 4  If One Connection Is Broken…
  • 9. • PC 1 • PC 2 • PC 3 • PC 4  If One Connection Is Broken…  The Entire Network Crashes
  • 10.  Similar To The Ring Topology With An Exception  The Computers Are Connected In A Loop    
  • 11.  Ring Topology is very orderly  Performs well under heavy network load  Doesn’t Require A Central Managing Sys.   
  • 12.  However, A Disconnection with one computer affects the entire network    
  • 13.  However, A Disconnection with one computer affects the entire network    
  • 14.  Also Adding Or Removing A Computer    
  • 15.  Also Adding Or Removing A Computer… Affects The Network >:( <_< (o_O )O.O :’( :D
  • 16.  Also Adding Or Removing A Computer… Affects The Network  Its Difficult To Configure >:( <_< (o_O )O.O :’( :D
  • 17.  Each Node Is Tied To A Central Point. The Switch. 8-) (__/) (o.O ) :D (^<^) ^_^
  • 18.  If One Connection Is Broken… 8-) (__/) (o.O ) :D (^<^) O.O
  • 19.  If One Connection Is Broken… The Others Aren’t Affected 8-) (__/) (o.O ) :D (^<^) 
  • 20.  Another Improvement… 8-) (__/) (o.O ) :D (^<^) ^_^
  • 21.  Another Improvement… Is That Packets Are Sent Directly To The Necessary Node Rather Than Through Each Node 8-) (__/) (o.O ) :D (^<^) ^_^ B R O
  • 22.  On The Flip Side, The Fact That Every Thing Is Connected To The Switch Means That… 8-) (__/) (o.O ) :D (^<^) ^_^
  • 23.  On The Flip Side, The Face That Every Thing Is Connected To The Switch Means That… If Anything happens To The Switch… :( (__/) (o.O ) :D (^<^) ^_^
  • 24.  On The Flip Side, The Face That Every Thing Is Connected To The Switch Means That… If Anything happens To The Switch… The Entire Network Is Affected :(    
  • 25.  Als0, These Networks Are Very Expensive To Set Up  And A Lot Of Wires Are Used In The Progress 8-) (__/) (o.O ) :D (^<^) ^_^
  • 26.  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
  • 27.  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    
  • 28.  That Way A Broken Connection…    
  • 29.  That Way A Broken Connection… Doesn’t Seriously Affect The Network    
  • 30.  That Way A Broken Connection… Doesn’t Seriously Affect The Network  Unless That’s The Gamers' Computer    
  • 31.  One Disadvantage Though Is That It Uses Quite A Lot Of Cables To Set Up The Network    
  • 32.  Tree Topology Are The Computers That Marry And Give Birth To Little Computers.  Ok Scratch That
  • 33.  Tree Topology Is The Order In Which Computers Rule Over Humans
  • 34.  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 $_$ ^_^   ^-^ 
  • 35.  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.
  • 36.  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”
  • 37.  ONCE AGAIN  The easiest way to add more computers into a network is by daisy-chaining
  • 38.  Not This one.
  • 39.  This one.
  • 40.  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.
  • 41.  Topology: The Design Or Shape In Which Nodes Are Connected On A Network.  There Are 8 Basic Topologies That Virtually All Networks Follow.
  • 42. •  PC 1 •  PC 2 •  PC 3 •  PC 4 8-) (__/) (o.O ) :D (^<^) ^_^    
  • 43.     $_$ ^_^   ^-^ 
