The different kinds of computer networks are determined by how the devices are linked to each other like the ring topology that looks like an oval and connects every device to two other devices or the bus topology, which includes a central line and connections for each device or the star topology with one central point of connection that all the other devices are connected to. Each of these has its pros and cons which is why you need to take your time deciding which one best fits your needs.
