During the installation of a network understanding the pattern and configuration of a network device and system is very important to solve such problems network topology is used which explains the network configuration
network connection and data exchange.

1 – What is Network Topology?
It is referred to as an arrangement of multiple systems and network devices interconnected to each other,
through a physical medium or logical
channel.
The term network topology is
combination of two individual network concept,
1st
Network Part
which represents the devices or
systems that are also known as nodes.
which is connected and how to change
the data within the network.
2nd
Topology
which represents the connection
medium between different network devices and governs the data flow between them,
2 – Why Apply Network Topology?
Advantages of Network: The first point it allows the users to understand the overall model of the network along with the number of devices installed and their positions in the network,
which provide ease of installation
of security measures and network and helps in case of troubleshooting cases.
understand
Network Concept: The next reason applying network topology helps the user to
understand the communication relationship among the different devices and
through a connection medium.
this in turn helps the network professionals
to set up an optimal network unit for the user.
3 – Different Types of Topology?
1 - Bus Topology.
2 - Ring Topology
3 - Star Topology
4 - Tree Topology and
5 - Mesh Topology
but to understand the concept of
topology
Start by point-to-point topology
this is simpler form of topology connection,
which consists of two nodes
connected through a connection medium like a network cable,
the nodes at the two ends of the
cable shares data information between them,
where the data sharing part
represents the network and the cable connection is the topology part,
with this we have understanding of network
topology,
then let's begin with complex types
of tech connections
1 - Bus Topology.
in this topology the connection channel
is a single cable known as the network backbone through which all the other nodes
are connected to,
in this network setting the data
packets sent by the nodes are provided with the receiver address to avoid
transmission errors,
the data in this topology can travel
from any end point,
where they are termed as terminate
points.
Advantages
of bus topology
Essay
Installaction, it is easy to set up due to the
simple configuration settings,
Cost
Effctive, this setting is also cost effective
as it requires only a network cable for the connection,
Prevent
Network failure, in the case of kreshnot the whole network
remains unaffected, as it does
not have any direct connection to
the other node,
Disadvantages
of bus topology
Complex
troubleshooting, In case of troubleshooting we
require
the use of special equipment to
detect
the fault in the network.
Network
Interference, In the case of multiple data
transmission the packet collision is the frequent occurrence damaging the
transmitted message data.
Loss
of Data, Due to the unavailability of
network devices such as switches repeaters etc, the loss of data over long
distances communication is quite high.
2 - Ring Topology
As the name suggests the node in the
network are connected in a circular pattern similar to a ring.
the data transmitted in this
connection is always in the clockwise direction.
the topology does not have any
termination point due to its ring structure.
the method of data transmission is
used is known as token passing,
which involves sending a token along
with the data packet to which each of the node matches to identify the
destination node using the destination address in the token.
Advantages
of ring topology
Batter
Network Management,the crash node can be easily removed
from the network,
Eassy
Installaction, the configuration settings are not complex for
setup and materials are easily accessible.
Cost
Effective, the cost of installation is low as
no extra network device are required to the connection.
Disadvantages
of ring topology
Network
Crach, In the case of a node crash the
whole system is affected and is non accessible due to the direct connection of
each node.
Slow
Data Transfer, the transfer of data is low due to
the token passing method in the network.
Problem
troubleshooting , Difficulty in the troubleshooting
fault in the connection leads to the trash of the whole network.
3 - Star Topology
this topology the networks are
connected to each other through the central hub,
which can be a computer or a server,
the central unit in the connection
is also known as the server and the nodes are known as the clients,
any connection between the node has
to be through the server and is one of the most popular topology connection.
Advantages
of star topology
Low
Error Chance, In case of a node crash the network
as a whole remains unaffected as each node is connected to the server of a
connection.
Essay
troubleshooting, The hardware requirements are
easily available and of low cost.
Efficient
Speed, Troubleshooting is easy through the
use of central hub to identify the faulty node.
Disadvantages
of star topology
Central Hub Failure, In case of a server failure the whole network is shut down as all nodes are interconnected through the server.
Connection
Issue, The connection configuration is
complex due to the pattern of the typology
4 - Tree Topology
This topology is a combination of tar and bus topology,
the node connection in the topology follows hierarchal pattern,
with the topmost node as the root and the branching node as the child node,
the sharing of data is from the root node to the child node pattern,
Advantages
of tree Topology
Eassy
Installaction, Installation of a new network group
is easy due to the root child configuration of the network.
Effective
Troubleshooting, In case of a node fault or trash
the whole network is not affected by the error this makes it easier to troubleshoot
the issue.
Disadvantages
of tree Topology
Crash
in central unit, In case of a server crash in any of
the star connection groups the whole network is affected.
Security Measues, due to the complex setting of the topology installing security points is difficult in the network.
Complex
Network, Configuring and troubleshooting
internal issues is quite complex due to this topology.
5 - Mesh Topology
As the name suggests this topology is a connection of interconnected system,
connected to each other in no particular order.
No installation of network devices such as switch or hubs,
this topology pattern can be divided into two forms.
Full match topology in this connection all the nodes are connected to each other in the network.
Partial mesh topology where all of the nodes are connected to each other available in the network.
Advantages
of mesh topology
Less Damage, In case of node damage the whole network does not suffer from the fault.
High
Speed Transmission, Due to the interconnected patterns
of the connection the transmission of data is very high in the network.
Disadvantages
of mesh topology
High Cost, The cost of installation is high due to the requirement of multiple cables and nodes for the network to function efficiently,
Network Management, The management of the network becomes complex due to the large number of interconnections in the network.
Complex
Connection, Due to the absence of repeater or a
switch the data signal loss during the transmission is very high.
4 – Which Network Topology of Choose
Cost
Effective, the installation cost is one of the
biggest factors that affects the type of topology configuration we choose from our
network,
As the cost of installing cables
routers switches and other network connections is slow.
Easy
Installation, installing the hardware devices
efficiently and precisely is also one of the factors that affect our choice of
network topology.
Flexibility
the ability of the topology to
include new network nodes after installation and ease of troubleshooting refers
to the flexibility of topology.
Reliable Security, it is important that the topology installed allows us to introduce proper security points in the network and leading the fewer cash cases by referring the above factors we can decide the best topology for our network.
