Network Topology: 6 Network Topologies Explained Jun 04, 2020 What is Topology? | Pure Mathematics | University of Waterloo Topology studies properties of spaces that are invariant under any continuous deformation. It is sometimes called "rubber-sheet geometry" because the objects can be stretched and contracted like rubber, but cannot be broken. For example, a square can be deformed into a circle without breaking it, but a figure 8 cannot. Hence a square is topologically equivalent to a circle,

WAN Topologies This increases costs slightly, but gives alternative routes in case of failure or congestion. Providing direct links between all possible pairs of nodes, a full mesh topology, requires a huge expense and is not at all scalable. This leads to the most typical high volume implementation. The Multitiered WAN. LAN Technologies | LAN Topology Types | Pearson IT The star topology is the most common topology in today's networks, and includes Ethernet, Fast Ethernet, and Gigabit Ethernet. Each node in a star topology connects to a dedicated link where the other end connects to a switch or hub. In the star-topology network shown in Figure 3.3, multiple devices are connected to a switch or hub.
Disadvantages of Star topology. 1. If hub goes down everything goes down, none of the devices can work without hub. 2. Hub requires more resources and regular maintenance because it is the central system of star topology. Bus Topology. In bus topology there is a main cable and all the devices are connected to this main cable through drop lines.
