In network topology, i am explaining about how to set a network, how many types of network topology, explanation of each type and its advantages and disadvantages. Linkedin - https://in.linkedin.com/in/prakharmaurya

2. What is a topology?
A topology is a description of the layout of
a specific region or area. A network
topology is a description of the layout of the
region or area covered by that network.
PRAKHAR

3. There are six basic topologies :
 1. BUS TOPOLOGY
 2. STAR TOPOLOGY
 3. RING TOPOLOGY
 4. MESH TOPOLOGY
 5. TREE TOPOLOGY
6.HYBRID TOPOLOGY

4. 1. BUS TOPOLOGY:
 Bus topology is a specific
type of network topology
in which all of the various
devices in the network are
connected to a single cable
or line.
PRAKHAR

5. Advantage:
 Easy to connect a computer or peripheral to a linear bus.
 Requires less cable length than a star topology.
 Entire network shuts down if there is a break in main cable or line.
 Bandwidth are divided due to this performance gets down.
 Difficult to identify the problem if the entire network shuts down.
Disadvantage:
PRAKHAR

6. 2.STAR TOPOLOGY:
 Star topology is a network
topology where each
individual piece of a
network is attached to a
central node (often called a
hub or switch). Star
topology is also known as
star network.
PRAKHAR

7. Advantage:
 Easy to install.
 No disruptions to the network when connecting or removing devices.
 Easy to detect fault.
 Require more cable length than bus topology.
 If the hub fails, nodes attached are disable.
 More expansive than bus topology because of the cost of the hub.
Disadvantage:
PRAKHAR

8.  It is a specific kind of
network setup in which
devices are connected in
a ring and pass
information to or from
each other according to
there adjacent proximity
in the ring structure.
3. RING TOPOLOGY:
PRAKHAR

9. Advantage:
 Very orderly network where every devices has access to the token and the
opportunity to transmit.
 Does not require a central node or hub to manage the connectivity between the
computers.
 Point to point line configuration make it easy to identify and isolate fault.
 Moving adding and changing the device can effect the network.
 Bandwidth is shared on all links between the devices.
 Communication delay is directly proportional to number of nodes in the network.
Disadvantage:
PRAKHAR

10.  A network setup where each
computer and network device is
interconnected with one another,
allowing for most transmissions to
be distributed, even if one of the
connections go down. This topology
is not commonly used for most
computer networks as it is difficult
and expensive to have redundant
connection to every computer.
4. MESH TOPOLOGY:
PRAKHAR

11. Advantage:
 It is efficient when one node fails other continue the work without disruption.
 Network can be easily expanded.
 You can send the data from one node to many nodes.
 It is quite expansive since a higher length of cable required.
Disadvantage:
PRAKHAR

12.  A tree topology is a type of
network topology that
includes at least three specific
level in a topology hierarchy.
Tree topology are valued for
there scalability and
accessibility for
troubleshooting.
5. TREE TOPOLOGY:
PRAKHAR

13. Advantage:
 It is the most suitable topology for large networks.
 Since it divides the network in sub-parts, so it becomes more manageable.
 If the backbone line breaks, the entire segment goes down.
 More difficult to configure and wire than other topologies.
Disadvantage:
PRAKHAR

14.  A network structure
whose design contains
more than one topology is
said to be hybrid
topology.
6. HYBRID TOPOLOGY:
PRAKHAR

15. Advantage:
 Since it divides the network in sub-parts, so it becomes more manageable.
 If the backbone line breaks, the entire segment goes down.
 More difficult to configure and wire than other topologies.
Disadvantage:
PRAKHAR
