Token Ring naturally uses the ring architecture. A mesh topology is usually found in a wide area network (WAN) to provide redundant paths between locations. See Ethernet and Token Ring.

In a network, this is often done through inputting a username and password. For networks that require high levels of security, this may include other factors. These are known as the three factors ...

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 ...

Figure 1: Network topology: biochemical reaction scheme versus causal connectivity. In cells, two main types of networks can be distinguished on the basis of their mode of action: gene networks ...

Bus topologies are not widely used in modern networking as they are not well suited to dealing with large amounts of data. They are used when a small, cheap and often temporary network is needed ...
