Topology Physical Network


Bus Topology
Bus Topology have the following characteristic :
1.Nodes connective serially alongside cable, and at both tip of cable closed over with terminator
2.Very simple in installation, also very economic in the case of expense
3.Packages data is sending each other at one cable of coaxial (cable the example of RG 58) so that if node which in circuit plenty of, network performance will go down cause often happened collision
4.Do not be needed by hub at network like this, which needed many is T-Connector in each card Ethernet
5.Problem which often happened is if one of the damage card Ethernet, or impedance at cable far above or under 50 ohm (for the cable of RG 58), hence entirety network earn down, so that all node cannot communicate in network


Ring Topology
Ring Topology have the following characteristic :
1.Nodes connective serially alongside cable, with network form like circle
2.Very simple in layout
3.Packages data emit a stream of in one way so that collision can be obviated
4.Problem faced is equal to bus topology

Star Topology
Star Topology have the following characteristic :
1.Each node communicate direct with concentrator, become data traffic emit a stream of from node to concentrator, then the data in broadcast to all node which in circuit to concentrator
2.Because each data package which step into concentrator then in broadcast to all node which in circuit to concentrator, hence if node which in circuit plenty of (for example wearing hub owning 32 port, and all port loaded), collision will often happened so that downhill network performance. But this matter do not happened if hub changed with hub switch, because switch have ability to chosen one band of is target of data, do not in broadcast to all port
3.Very easy developed by because every node only in circuit directly to concentrator
4.If one of the damage card Ethernet, or one of the broken cable, hence overall of network still communicate, do not happened down at entirety network
5.Type used cable usually cable have type to of UTP
