Which network topology allows all traffic to flow through a central hub?

A.
bus

B.
star

C.
mesh

D.
ring

Explanation:
Star topology is the arrangement of the computers in such a way that all the terminals or work stations are connected to the main central hub. The terminals are
referred to as the clients and the main central hub is referred to as the switch. It is the easiest way of arranging a network topology with one central main computer
connected to several other functioning terminals. All the network traffic passes through the central device and all the data transmission occurs through the main
switch as well as all the hub acts as the signal repeater. One advantage of such an arrangement is the simplicity and the ease with which you can add additional
nodes. The disadvantage is that if an error occurs in the central hub the whole network shuts down.
