Transcript

  • 1. Network topologies By: Anam jabeen
  • 2. DEFINITION • What is a Topology ? • The physical topology of a network refers to the configuration of cables, computers and other peripherals.
  • 3. Types of Topologies • • • • • • Bus topology Ring topology Star topology Mesh topology Tree topology Hybrid topology
  • 4. Bus Topology • Popular on LANs because they are inexpensive and easy to install. • Consists of a main run of cable with a terminator at each end • All computers and devices connected to central cable or bus.
  • 5. Bus topology
  • 6. Ring Topology • Primarily is used for LANs, but also is used in WANs. • Data travels from device to device around entire ring, in one direction. • Cable forms closed ring or loop, with all computers and devices arranged along ring.
  • 7. Ring Topology
  • 8. Star Topology All devices connect to a central device, called hub. All data transferred from one computer to another passes through hub.
  • 9. Star Topology
  • 10. Mesh Topology • A network setup where each computer and network device is interconnected with one another. • This topology is not commonly used for most computer networks as it is difficult and expensive.
  • 11. Mesh Topology
  • 12. Tree topology • A tree topology combines the characteristics of bus and star topologies. • It consists of different groups of computers attached in star topology. • The groups are then connected to a bus backbone cable. • Tree topology is used for the expansion of an existing network.
  • 13. Tree topology
  • 14. Hybrid Topology • A combination of two or more different topologies makes a hybrid topology. • One of the prominent advantages of this topology is its flexibility • Since different topologies come together in a hybrid topology, managing the topology becomes difficult. • It is also very expensive to maintain.
  • 15. Hybrid Topology
