- 1. JAWAHAR NAVODAYA VIDYALAYA KILTAMPALEM, VIZIANAGARAM DONE BY: RUKMINI DASARI 12TH CLASS (17)
- 3. Certificate Certified that the project report entitled NETWORK TOPOLOGIES submitted by RUKMINI DASARI in her own and has been supervision. It is recommended that this project be placed before the examinist for evalution . Signature of guided examiner signature of external signature of principal
- 4. Acknowledgement This is to acknowledge all those without whom this project would not have been reality . Firstly,I would wish to thank our computer science teacher mrs malika parveen who gave her immense support dedicated her time towards it and made us understand how to make this project . Without her guidance ,the project would not have been complete.the matter contain in it has been widely taken from the internet.the source of the news paper article is the independent ,and the statistical data has been extracted from school database .
- 5. The way in which the computer devices are physically interconnected to form a network is called a topology It can be defined as the arrangement or structure of network .
- 7. Typesof topologies . Bus topology Star topology Tree topology
- 8. In bus topology all the nodes are connected to a main cable called backbone . If any node has to send some information to any other nodes ,it sends the signal to the backbone .The signal travels through the entire length of the backbone and is received by the node for which it is intended A small device called terminator is attached at each end of the backbone .When the signal reaches the end of backbone ,it is absorbed by the terminator and the backbone gets free to carry another signal.
- 9. Bus topology
- 10. Characteristics–bus topology It is easy to install It requires less cable length and hence it is cost effective Failure of a node doesnot effect the network In case of cable (backbone) or terminator fault ,the entire network breakdowns Fault diagnosis is difficult. At a atime only one node can transmit data .
- 11. Advantages of the linear topology Short cable length and simple wiring layout Resilient architecture Easy to extend
- 12. Disadvantages of the linear topology Fault diagnosis is difficult. Fault isolation is difficult. Repeater configuration. Nodes must be intelligent.
- 13. Star topology This topology consists of a central node tonwhich all other nodes are connected by a single path .
- 14. Advantages of star topology Ease of service One device per connection Centralized control/problem diagnosis Simple access protocols
- 15. Disadvantages of the star topology Long cable length Difficult to expand Central node dependency
- 16. Tree topology A variation of bus topology is the tree topology. The shape of the network is that of an inverted tree with the central root branching and subranching to the extremities of the network.
- 18. Advantages of the tree topology It uses point to point wiring for individual segments It is supported by several hardware and software venders.
- 19. Disadvantages of the tree topology Overall length of each segment is limited by the type of cabling used. If the backbone line breaks,the entire segment goes down. It is difficult to configure and wire then other topologies.
- 20. DECLARATION I THE UNDERSIGNED SOLEMNLY DECLARE THAT THE PROJECT REPORT ON NETWORK TOPOLOGIESIS BASED ON MY OWN WORK CARRIED OUT DURING THE COURSE OF STUDY UNDER THE SUPERVISION OF MALIKAPARVEEN .I ASSERT THE STATEMENT MADE AND CONCLUSIONS DRAWN AND OUTCOME OF MY RESEARCH WORK IS THE REPORT IS ORIGINAL AND HAS BEEN DONE BY ME UNDER THE GENERAL SUPERVISION OF MY SUPERVISOR
