Topologies: BUS & STAR

BUS & STAR

Now we move on to BUS topology.  In a BUS topology, all the nodes are connected to a backbone line cable and the cable has a terminate at its end to terminates the signal.

Then the signal bounces back.  Each node has a unique identifier.  When a node needs to communicate it sends a broadcast packet which travels throughout the backbone that is received by all the nodes on the network but only acknowledged and responded to by the target.

You’ll learn what happens when the target node doesn’t acknowledge its pack, what role the terminators have, what if any advantages it may have, why it could be a cost effective network solution, and what if anything happens when a single node goes down.

With a Star topology, you’ll learn what a central hub is and what the factors are for defining a point as a central hub within a Start topology.

You’ll learn the advantage of each node device having one connection to the network, the ease of the Star topology’s in terms of setup, expansion, troubleshooting device connection and internet connectivity issues.
