Type of topology:
Mesh topology
Bus topology
Ring topology
description
-when all the devices are connected to each other it is a -full mesh-
-when some devices are connected to all other devices it is a -partial mesh-
-it connects all the network devices through a central cable.
-data are transmitted from one device to another down the bus.
-all the nodes are connected to a giant ring of cable that has no real begging or end.
-all messages travel through a ring in the same direction.
Advantages:
1-data has many paths to be transmitted through.
2-the network still work even though a part of it fails.
1-easy to set up and extent bus network.
2-it costs very less.
3-linear bus network is mostly used in small networks.
1-each computer has equal access to resources.
2-Additional components do not affect the performance of network
3-even when the load on the network increases it’s performance is better than of bus topology
Dis-advantages:
1-there are high chances of redundancy in many network connections.
2-the over all cost of this network is very high.
1-secuirty is very low.
2- if the central cable fails the network fails.
3-there is a limit on central cable length and number of nodes that can be connected.
1-network is highly dependent on wire which connects different components.
2-if one work-station or port goes down the entire network gets affected.
1-intranet:
-it is a private network within the organization.
-only employees have access to it.
-used to achieve many tasks such as: coordinating internal emails, making company publications, providing access to shared calendars and schedule, facilitating collaborative computing.
-An intranet uses: TCP/IP, HTTP and other internet protocols and in general looks like a private version of the internet.
2-Extranet:
-An extranet is a private network that uses internet technology and the public tele-communication system to securely share part of bussiness’s information with...
