### Network topology

1. 1. FROM ALFIA FATMA TAPESH CHALISGAONKAR
2. 2. Main Menu OBJECTIVE CONTENT EXERCISE SUMMARY EXIT
3. 3. At the end of this lesson, student should be able to achieve all the three objective below:- OBJECTIVE MAIN MENU SUMMARY EXITEXERCISECONTENT At the end of this lesson, student should be able to achieve all the three objective below:- Explain meaning of network topology with correctly. State three types of network topologies correctly. Differentiate correctly between the three types of network topology.
4. 4. CONTENT MAIN MENU SUMMARY EXITEXERCISEOBJECTIVE Definition of Network Topology Types of Network Topology Differentiation Between the Types of Network Topology
5. 5. DEFINITION What is a Topology ? The physical topology of a network refers to the configuration of cables, computers and other peripherals. MAIN MENU SUMMARY EXITEXERCISEOBJECTIVE
6. 6. TYPES OF NETWORK TOPOLOGY Three commonly used network topologies are:- Bus network. Ring network. Star network. MAIN MENU SUMMARY EXITEXERCISEOBJECTIVE
7. 7. BUS TOPOLOGY All computers and devices connected to central cable or bus. Consists of a main run of cable with a terminator at each end. Popular on LANs because they are inexpensive and easy to install. MAIN MENU SUMMARY EXITEXERCISEOBJECTIVE
8. 8. BUS TOPOLOGY MAIN MENU SUMMARY EXITEXERCISEOBJECTIVE
9. 9. BUS TOPOLOGY MAIN MENU SUMMARY EXITEXERCISEOBJECTIVE
10. 10. RING TOPOLOGY Cable forms closed ring or loop, with all computers and devices arranged along ring. Data travels from device to device around entire ring, in one direction. Primarily is used for LANs, but also is used in WANs. MAIN MENU SUMMARY EXITEXERCISEOBJECTIVE
11. 11. RING TOPOLOGY MAIN MENU SUMMARY EXITEXERCISEOBJECTIVE
12. 12. STAR TOPOLOGY All devices connect to a central device, called hub. All data transferred from one computer to another passes through hub. MAIN MENU SUMMARY EXITEXERCISEOBJECTIVE
13. 13. STAR TOPOLOGY MAIN MENU SUMMARY EXITEXERCISEOBJECTIVE
14. 14. STAR TOPOLOGY MAIN MENU SUMMARY EXITEXERCISEOBJECTIVE
15. 15. DIFFERENTIATION BETWEEN THE THREE TYPES OF NETWORK TOPOLOGY MAIN MENU SUMMARY EXITEXERCISEOBJECTIVE WHAT IS DIFFERENTIATION BETWEEN THE THREE OF NETWORK TOPOLOGY? SEARCH IN THE INTERNET
16. 16. DIFFERENTIATION BETWEEN THE THREE TYPES OF NETWORK TOPOLOGY MAIN MENU SUMMARY EXITEXERCISEOBJECTIVE http://en.wikipedia.org/wiki/Network_topology http://home.att.net/~charlie.net/cMctopology.htm
17. 17. DIFFERENTIATION BETWEEN THE THREE TYPES OF NETWORK TOPOLOGY MAIN MENU SUMMARY EXITEXERCISEOBJECTIVE ADVANTAGE DISADVANTAGE 1) Easy to connect computer or peripheral to a linear bus. 1) Entire network shuts down if there is a break in the main cable. 2) Requires less cable length than a star topology. 2) Terminators are required at both ends of the backbone cable. 3) Difficult to identify the problem if the entire network shuts down. BUS
18. 18. DIFFERENTIATION BETWEEN THE THREE TYPES OF NETWORK TOPOLOGY MAIN MENU SUMMARY EXITEXERCISEOBJECTIVE ADVANTAGE DISADVANTAGE 1) Data is quickly transferred without a ‘bottle neck’. 1) Data packets must pass through every computer between the sender and recipient therefore, this makes it slower. 2) The transmission of data is relatively simple as packets travel in one direction only. 2) If any of the nodes fail then the ring is broken and data cannot be transmitted successfully. 3) It is difficult to troubleshoot the ring. RING
19. 19. DIFFERENTIATION BETWEEN THE THREE TYPES OF NETWORK TOPOLOGY MAIN MENU SUMMARY EXITEXERCISEOBJECTIVE ADVANTAGE DISADVANTAGE 1) Easy to install and wire. 1) Requires more cable length than a linear topology. 2) Security can be implemented in the hub/switch. 2) If the hub or concentrator fails, nodes attached are disabled. 3) Easy to detect faults and to remove parts. 3) More expensive than linear bus topologies because of the cost of the concentrators. STAR
20. 20. EXERCISE MAIN MENU SUMMARY EXITCONTENTOBJECTIVE 1) Which of the following statements describe about network topology correctly ? A. Devices attached or detached at any point on the network. B. The failure of device on the network. C. Refers to the configuration of cables, computers and other peripherals. D. All of the above.
21. 21. EXERCISE MAIN MENU SUMMARY EXITCONTENTOBJECTIVE 2)On a __________, all of the computers and devices (nodes) on the network connect to a central device. A. Bus network. B. Ring network. C. Star network. D. All of above.
22. 22. EXERCISE MAIN MENU SUMMARY EXITCONTENTOBJECTIVE 3)On a star network, the central device that provides a common connection point for nodes on the network is called the __________. A. Hub. B. Personal computer. C. Printer. D. File server.
23. 23. EXERCISE MAIN MENU SUMMARY EXITCONTENTOBJECTIVE 4) On a bus network, such as that illustrated in the accompanying figure, if one node fails ________. A. Only that node is affected. B. Only the nodes before that node are affected. C. Only the nodes after that node are affected. D. All the nodes are affected.
24. 24. EXERCISE MAIN MENU SUMMARY EXITCONTENTOBJECTIVE The transmission of data is relatively simple as packets travel in one direction only. 5) The statement above is correctly refer to the ______. A. Bus network. B. Ring network. C. Star network. D. All of the above.
25. 25. EXERCISE MAIN MENU SUMMARY EXITCONTENTOBJECTIVE 6) All the statements true about ring topology except A. Data is quickly transferred without a ‘bottle neck’. B. The transmission of data is relatively simple as packets travel in one direction only. C. If any of the nodes fail then the ring is broken and data cannot be transmitted successfully. D. Security can be implemented in the hub/switch.
26. 26. EXERCISE MAIN MENU SUMMARY EXITCONTENTOBJECTIVE 7) The statement true about star topology is A. Difficult to identify the problem if the entire network shuts down. B. Terminators are required at both ends of the backbone cable. C. The transmission of data is relatively simple as packets travel in one direction only. D. Easy to detect faults and to remove parts.
