Thanks a lot for this informative guide. I think star topology is most useful, because there are less chances of network failure, as compared to ring and bus network topologies.

er I have always understood that there a four main toplogies and the one missing is Mesh. Strictly speaking there are 7 but these a variants of the 4 main. See: http://en.wikipedia.org/wiki/Network_topology SWW

- Slide 3: OBJECTIVE At the end of this lesson, student should be able to achieve all the three objective below:- Explain meaning of network topology with correctly. At the end of this lesson, student should be able to achieve all the three objective below:- State three types of network topologies correctly. Differentiate correctly between the three types of network topology. MAIN MENU CONTENT EXERCISE SUMMARY EXIT

- Slide 5: DEFINITION What is a Topology ? The physical topology of a network refers to the configuration of cables, computers and other peripherals. MAIN MENU OBJECTIVE EXERCISE SUMMARY EXIT
- Slide 6: TYPES OF NETWORK TOPOLOGY Three commonly used network topologies are:- Bus network. Ring network. Star network. MAIN MENU OBJECTIVE EXERCISE SUMMARY EXIT
- Slide 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 OBJECTIVE EXERCISE SUMMARY EXIT
- Slide 8: BUS TOPOLOGY MAIN MENU OBJECTIVE EXERCISE SUMMARY EXIT
- Slide 9: BUS TOPOLOGY MAIN MENU OBJECTIVE EXERCISE SUMMARY EXIT
- Slide 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 OBJECTIVE EXERCISE SUMMARY EXIT
- Slide 11: RING TOPOLOGY MAIN MENU OBJECTIVE EXERCISE SUMMARY EXIT
- Slide 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 OBJECTIVE EXERCISE SUMMARY EXIT

- Slide 17: DIFFERENTIATION BETWEEN THE THREE TYPES OF NETWORK TOPOLOGY BUS ADVANTAGE DISADVANTAGE 1) Easy to connect computer or 1) Entire network shuts down if peripheral to a linear bus. there is a break in the main cable. 2) Requires less cable length 2) Terminators are required at both ends of the backbone than a star topology. cable. 3) Difficult to identify the problem if the entire network shuts down. MAIN MENU OBJECTIVE EXERCISE SUMMARY EXIT
- Slide 18: DIFFERENTIATION BETWEEN THE THREE TYPES OF NETWORK TOPOLOGY RING ADVANTAGE DISADVANTAGE 1) Data is quickly transferred 1) Data packets must pass without a ‘bottle neck’. through every computer between the sender and recipient therefore, this makes it slower. 2) The transmission of data is 2) If any of the nodes fail then the relatively simple as packets ring is broken and data cannot be travel in one direction only. transmitted successfully. 3) It is difficult to troubleshoot the ring. MAIN MENU OBJECTIVE EXERCISE SUMMARY EXIT
- Slide 19: DIFFERENTIATION BETWEEN THE THREE TYPES OF NETWORK TOPOLOGY STAR ADVANTAGE DISADVANTAGE 1) Requires more cable length 1) Easy to install and wire. than a linear topology. 2) Security can be implemented 2) If the hub or concentrator fails, nodes attached are in the hub/switch. disabled. 3) Easy to detect faults and to 3) More expensive than linear bus topologies because of the remove parts. cost of the concentrators. MAIN MENU OBJECTIVE EXERCISE SUMMARY EXIT
- Slide 20: EXERCISE 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. MAIN MENU OBJECTIVE CONTENT SUMMARY EXIT
- Slide 21: EXERCISE 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. MAIN MENU OBJECTIVE CONTENT SUMMARY EXIT
- Slide 22: EXERCISE 2) 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. MAIN MENU OBJECTIVE CONTENT SUMMARY EXIT
- Slide 23: EXERCISE 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. MAIN MENU OBJECTIVE CONTENT SUMMARY EXIT
- Slide 24: EXERCISE 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. MAIN MENU OBJECTIVE CONTENT SUMMARY EXIT
- Slide 25: EXERCISE 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. MAIN MENU OBJECTIVE CONTENT SUMMARY EXIT
- Slide 26: EXERCISE 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.
