Network Topology:
1.Mesh Topology
2.Bus Topology
3.Star Topology
4.Ring topology
5.Hybird Topology
Ring Topology:
| No. of Nodes (N) | No. of Cables (=N) | No. of ports/device (NOP) | Total No. of ports in the Network (TNOP) = N X NOP |
| 2 | 2 | 2 | 4 |
| 3 | 3 | 2 | 6 |
| 4 | 4 | 2 | 8 |
| N | N | 2 | 2 X N |
1.Identify the given topology and determine how many cables and ports are required to have such network?
one answer use more question
For example, Ring Topology
Solution: (Here N=6)
No. of Cables = N
No. of Cables = 6
TNOP = N X NOPD
N = 2, NOPD = 6
TNOP = 2 X 6=12
2.Traffic problem can be minimized using?
a. Bus
b. Ring
c. Star
d. Mesh
Answer: d. Mesh
3.Assume six devices are arranged in a mesh topology. How many cables are needed? How many ports are needed?
a. 15,5
b. 6,5
c.30,5
d. 5,5
Answer: a. 15,5
Solution:(Cables)
N=6
NOC = N(N -1) / 2
6(6 -1) / 2
6(5) / 2
30 / 2
NOC = 15 cables

5)Which network topology requires a central controller or hub?
a) Mesh
b) Star
c) Ring
d) Bus
Answer: b. Star
