11b, 100Base-FX 10Base2, 10Base5, FDDI, 802. Devices in different types of network topologies pdf bus topology are connected to a central cable.
In this type of network, both cable ends must be terminated. A defective cable segment, and changes and additions can affect the entire network. Devices in a star topology are connected through a central hub. In this type of network, new nodes can be easily added making it easy to expand.
Multiple connected star networks can form a large star or hierarchical topology. The central hub , which physically can be a hub, switch, or router, forms a single-point-of-failure. Another disadvantage is the increased amount of required cabling. In a ring topology, every node is logically connected to two other nodes , forming a ring.
