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 ...

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 ...

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.

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 ...

Dual switch QR flyback topology and secondary synchronous rectification is the ideal solution to meet future energey regulation - providing good overall efficiency, managing low power loss at light ...
