Topologies refer to the way networks are connected. Different topologies have different advantages.
what are the different networking topologies?
The redundancy is nothing but the reduction.The temporal locality is of relating to short time requirements.And the spatial is of relating to over environment.The redundancy occur in the images are of most common,so many techniques applied to overcome this. In image temporal redundancy is of abrupt transitions while in spatial it is of block based transitions.Spatial is applied at minimum cost and temporal is at maximum cost.Threshold values apply to temporal redundancy and the pixel comparison technique applies to spatial redundancy.

There is actually more than three topologies for networking. Network topologies are categorized into the following basic types: * bus * ring * star * tree * mesh More complex networks can be built as hybrids of two or more of the above basic topologies.
Logical topologies consist of virtual connections between nodes.
Star topologies. Sometimes combined topologies are used of which i have no idea!! :P
Mesh topologies and SONET rings.
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.
