A physical topology is how they are actually interconnected with wires and cables. For example, in a shared Ethernet network that uses hubs rather than switches, the logical topology appears as if ...

For each example we find compelling evidence for the sometimes startling fact that in a geometric figure three straight lines, or sometimes circles, pass through one and the same point. Of course, we ...

the whole network fails if the switch fails as no node can communicate a wired star topology requires plenty of cable - in a large network this can be expensive Star topologies tend to be found in ...

The class of EDS is therefore quite large and encompasses virtually all natural examples (although artificial non-examples can be constructed, see §8). Our main tool will be the following result. We ...

A network's topology is the arrangement, or pattern, in which all nodes on a network are connected together. There are several common topologies that are in use, but today the most common ...

The method is commonly used in statistics, a branch of applied mathematics, to obtain a sample that is representative of the larger population. The simple random sampling method allows researchers ...
