Network Topologies (Click here for more info…)


All computers communicate in the same way. They prepare a signal to send to an address and place it on a transmission medium (i.e. wire/wifi signal). However, the way in which the computers on a network are laid out varies and can have effects on the cost and performance of a network. There are three topologies you need to know about – bus, ring and star.
