5. At the end of this lesson, student should be able to achieve all the three objective below:- OBJECTIVE At the end of presentation, student will be able to achieve all the three objective below:- Explain meaning of network topology with correctly. State five types of network topologies Correctly with advantage and disadvantage. Differentiate correctly between the five types of network topology. QASIM KHAN ZAID-UR-REHMAN MUHAMMAD FAIZAN AHMED FARDEEN
6. CONTENT Definition of Network Topology Types of Network Topology Differentiation Between the Types of Network Topology QASIM KHAN ZAID-UR-REHMAN MUHAMMAD FAIZAN AHMED FARDEEN
7. DEFINITION What is a Topology ? Topology is a Branch of Mathematic in which we study about the arrangement of element. In term of Computer networking “ The structure, consisting of paths and switches, that provides the communication interconnections among nodes of a network” QASIM KHAN ZAID-UR-REHMAN MUHAMMAD FAIZAN AHMED FARDEEN
8. TYPES OF NETWORK TOPOLOGY Types of Topology PHUSICAL TOPOLOGY LOGICAL TOPOLOGY PHYSICAL TOPOLOGY:- “ THE PHYSICAL TOPOLOGY OF A NETWORK REFERS TO THE LAYOUT OF CABLES, COMPUTERS AND OTHER PERIPHERALS ” . LOGICAL TOPOLOGY:- “ LOGICAL TOPOLOGY IS THE METHOD USED TO PASS THE INFORMATION BETWEEN THE COMPUTERS” QASIM KHAN ZAID-UR-REHMAN MUHAMMAD FAIZAN AHMED FARDEEN
9. TYPES OF PHYSICAL NETWORK TOPOLOGY Three commonly used network topologies are:- Ring network. Star network. Tree network. Bus network. QASIM KHAN ZAID-UR-REHMAN MUHAMMAD FAIZAN AHMED FARDEEN Mesh network.
14. In a tree network all computers are connected in a hierarchal fashion. Require data flow through the branches. A tree topology combines characteristics of linear bus and star topology. TREE TOPOLOGY QASIM KHAN ZAID-UR-REHMAN MUHAMMAD FAIZAN AHMED FARDEEN
22. ADVANTAGES AND DISADVANTAGES OF STAR TOPOLOGY STAR QASIM KHAN ZAID-UR-REHMAN MUHAMMAD FAIZAN AHMED FARDEEN 2) Failure of the switch or hub can disable the entire network. 2) Security can be implemented in the hub/switch. 1) Requires more cable length than a ring or bus topology. 1) Easy to install and wire. 3) More expensive than linear bus topologies because of the cost of the concentrators. 3) Easy to detect faults and to remove parts. DISADVANTAGES ADVANTAGES

24. QASIM KHAN ZAID-UR-REHMAN MUHAMMAD FAIZAN AHMED FARDEEN The Internet is a series of interconnected networks. Personal computers and workstations are connected to a Local Area Network ( LAN ) by either a dial-up connection through a modem and standard phone line or by being directly wired into the LAN. INTERNET TOPOLOGY
30. ADVENTAGES AND DISADVENTAGES OF BUS NETWORK TOPOLOGY BUS QASIM KHAN ZAID-UR-REHMAN MUHAMMAD FAIZAN AHMED FARDEEN 2) Terminators are required at both ends of the backbone cable. 2) Requires less cable length than a star topology. 1) Entire network shuts down if there is a break in the main cable. 1) Easy to connect computer or peripheral to a linear bus. 3) Difficult to identify the problem if the entire network shuts down. DISADVANTAGES ADVANTAGES
33. MESH TOPOLOGY QASIM KHAN ZAID-UR-REHMAN MUHAMMAD FAIZAN AHMED FARDEEN Not common on LANs Most often used in WANs to interconnect LANS Each node is connected to every other node Allows communication to continue in the event of a break in any one connection
