There are various this website different types of computer networks. Which network an organization utilizes depends upon elements including the amount of units, forms of working systems, transmission medium utilized, network topology, the space involving Each individual device as well as their geographic scale.
My wager is that for a minimum of a number of them, the backplane will not be quickly more than enough for complete, non-blocking packet exchange concerning all ports.
