The document discusses different network topologies, including ring, bus, star, and tree. It defines topology as the physical arrangement of connecting computers for networking. Each topology type is then described in 1-2 sentences, noting their basic structure and some advantages and disadvantages. The ring topology has all nodes joined in a ring with no central server, while the bus topology shares a common connecting cable between all nodes. The star topology connects all nodes to a centralized computer, and the tree topology links nodes in stages or phases.

2. TOPOLOGY
Topology is physical arrangement of connecting
various computer for networking.

3. TYPES OF TOPOLOGY
 Ring topology
 Bus topology
 Star topology
 Tree topology

4. RING TOPOLOGY
Here all the nodes are joined together to form
a ring. There is no central server in this case.
ADVANTAGES:
 Short cable length
 Suitable for optical fibres
DISADVANTAGES:
 Network reconfiguration is difficult
 Topology affects the access protocol

5. BUS TOPOLOGY
Here all the nodes share a common bus of
connecting cables.
ADVANTAGES:
 Short cable length and simple wiring layout
 Easy to extend
DISADVANTAGES:
 Fault identification is difficult
 Fault isolation is difficult

6. STAR TOPOLOGY
Here all the nodes are connected to a
centralized computer.
ADVANTAGES:
 Fault identification is easy
 Fault isolation is easy
DISADVANTAGES:
 Long cable length
 Difficult to expand

7. TREE TOPOLOGY
Here nodes are linked in a stage or phase.
ADVANTAGES:
 Easy to expand
 Fault isolation is easy
DISADVANTAGES:
 Dependent on the root
 Difficult for installation
