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 ...

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 ...

While you don't need topology to determine that you are living on something like a giant beach ball, knowing all the possible 2D spaces can be useful. Over a century ago, mathematicians figured ...

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 ...
