Q. 1. Different topologies behave
differently when a connection fails. You are required to discuss the effect on
the network when only one device connection fails in the following cases: [2 x 6 = 12 Marks]
- Seven devices are connected through a ring
topology.
- Six devices are connected through a dual
ring topology.
- Four devices are connected through a mesh
topology.
- Twelve devices are connected through a star
topology (Note: Do not consider the hub failure).
- Fifteen devices are connected through a star
topology and only the hub is failed.
- Eight devices are connected through a bus
topology.
Note: Your answer for Q.1 should
be in the same order as given in the question statements.
Q. 2. Suppose a
small company wants to develop a computer network of 18 computers in its main
office. Due to limited resources the company wants a network architecture where
a single communication medium can be shared among all other nodes. Considering
this scenario, you are required to suggest the suitable line configuration and
name all the possible ways through which your suggested line configuration can
be implemented. [3 Marks]
