The internet uses a very complex topology, due to the massive number of nodes and the high redundancy that is characteristic of high availability systems like the internet. Different parts of the internet look like different topologies. The internet would be best approximated as a mesh topology.
For an image of a simple mesh topology, and a discussion of the different possible network topologies, see the wikipedia article in the links below.
ring
A star topology.
No, modern LANs use a star topology
Bus Topology
tpology are mainly three types (1) STAR TOPOLOGY,(2)BUS TOPOLOGY,(3)RING TOPOLOGY
Bus topology is extended via the use of repeaters.
yes, network topology does matter to design a network. as we know that topology is a structure of network. without a topology network cannot be designed. we have to consider which topology to use and what does each topology does. different topology have its different features. if you want most secure connection use full mesh topology
Sure, the machines have to be connected somehow. A star topology is quite common.
the partially connected topology is best for the wan because it us
Mainframe computers first used star topology
Mesh Topology... though if you use a beefy-enough machine in the middle, a Star topology might work.
SONET use RING physical topology and TOKEN logical topology. As simple as that. Logical topology deals with the data transmission. Physical topology deals with how the network is connected physically , BUS, RING, STAR and the like.
