TYPES OF NETWORK TOPOLOGY : :pencil2: (BUS TOPOLOGY (Advantages (1.1.It…
TYPES OF NETWORK TOPOLOGY
1.cables fails then whole network fails
2.if network trafic is heavy or nodes are more the performance of the network decreases
3.cable has a limited length
4.it is slower than the ring topology
1.It transmits data only in one direction
2.Every device is connected
1.1.It is cause effactive
2.cable required is least compareed to other network topology
3.Used in small networks
4.It is easy to understand.
5.Easy to expand joining two cables together.
The nodes have a routing logic,as per the network requirements . routing logic which has information about the broken links,and it avoids those node etc.we can even have routing logic , to re-configure the failed nodes.
The same data is transmitted to all the network nodes,hence no routing logic is required . the network is robust,and the its very unlikely to lose the data.
PARTIAL MESH TOPOLOGY
In this topology some of the systems are connected in the same fashion as mesh topology but some device are only connected two or three devices .
FULL MESH TOPOLOGY
Each and every nodes or devices are connected to each other .
each connection can carry its own data load.
it is robust
fault is diagnosed easily
provides security and privacy.
installation and configuration is difficult
cabling cost is more
bulk space wiring is required
Types of Mesh
It is a point-to-point connection to other nodes or devices. all the network nodes are connected to each other. mesh has n(n-1)/2 physical channels to link n device
1.transmitiing networkis not affected by high trafic or by adding more nodes, as only the nodes having tokes can tranmit data
2.cheap to install and expand.
1.A number of repeaters are used for ring topology with large number of nodes
2.the transmition is undirectional it can be made bidirectional by having two connection between each network node, it is call dual ring topology
3.in dual ring topology, two ring network are formed, and data flow is in opposite direction in them
4.data is transfered in the sequential manner that is bit by bit.
1.trouble shooting is difficult in ring topology
2.adding or deleting the computers disturbs the network activity
1.cost of installation is high
2.expensive to use
3.if the hub fail then the whole network is stopped because all the nodes depend on the hub
4.performance is based on the hub that is it depands on its capacity
1.fast performance with few node and low network trafic
2.hub can be upgraded easily
4.easy to setup and modified
5.only that node is affected which has failed , rest of the nodes can work smoothly
3.easy to troubleshoot
1.every node has its own dedicated connectin to the hub
2.hub act as a repeater for data flow
3.can be used with twisted pair, obticle fiber or coaxial cable
1.if workstations are located in group .
2.used in WAN .
2.if more nodes are added maintenance is difficult
1.extention of bus and star topologies
expansion of nodes is possible and easy
3.easily managed and maintained
4.error detection is easily done
1.it is a combination of two or topologies.
2.inherits the advantages and disadvantages of the topologies included.
1.complex in design
1.reliable as Error detecting and troubleshooting is easy.
3.scalable as size can be increased easily
