On the CCENT test there'll be many alternative questions about network topologies. Network topologies square measure simply completely different ways that square measure wont to connect a bunch of computers along.
Below you may realize an inventory of seven alternative ways of connecting computers. Some square measure additional strong than others, that means that they're ready to still perform somewhat if a mistake happens. alternative topologies will be fully broken if one single link goes down. There square measure prices and advantages to any or all the various topologies.
The Token Ring Topology
To be honest i am not extremely positive why you would like to understand concerning the token ring topology for the CCENT test as a result of it's AN recent approach of connecting computers that's not used. but it's invariably nice to understand wherever we've come back from. Computers within a token ring network square measure connected along in an exceedingly circle (or a ring) and a pc cannot send knowledge unless it's the token. The and facet to victimization the token ring topology is that no collisions will occur. The down facet is that it's very slow.
The Network Topology
The majority of tiny to medium sized networks can use the beginning topology. And similar to the name implies you connect the computers in an exceedingly star like fashion with a switch situated within the center and so the computers square measure connected to the switch like points on a star. One downside with the network topology is that the switch might fail and also the entire network would go down. a decent factor concerning the network topology is that once a pc fails the remainder of the network will still perform.
The Extended Network Topology
When you be part of one network topology with ANother existing network topology by one in every of its star points you produce an extended star. you'll have many alternative star topologies connected to every alternative, simply keep in mind that if one in every of routers or switches connecting to a different star breaks that entire network topology connected off of it'll become unaccessible.
The Full-Mesh Topology
This is the foremost high-priced kind of topology to implement, however it is also the foremost sturdy. notwithstanding what number computers you have got in your network so as for it to be fully-meshed, every pc is coupled to each alternative pc. this will be very tough to implement in an exceedingly giant network. the nice factor a few fully-meshed network is once one link breaks, the network does not break as a result of there square measure still many alternative routes which will be wont to reach that network.
The Partial-Mesh Topology
Because a full-mesh topology is therefore high-priced to
form a partially-meshed network is far additional common. in an exceedingly
partially-meshed network solely those very crucial connections can have quite
one route to them, however the less crucial connections can solely have one
route to save lots of on value.
