Hello, everyone.
So in this video we are going to understand about Network
topologies. So we will
see what a network topology.
What are the types of topologies?
understanding each topology and seeing the difference between
all
so
let's start with the bus topology.
So as you can see.
There are many computers connected.
we call this computers as nodes as node
a node B node C note D
node e and node f
All these computers are nodes are
connected to each other with a wire
called as backbone.
so, let's see the working of bus type of
Network
so
let's say if a wants to transmit a
message.
to f
so
it will take the message and transfer first.
To the D node through the
backbone.
As it is the closest to
a on to the network the node
D is not the recipient
which is intended to get the
message. So it will discard that message which
the a has sent it.
now it will travel onto the backbone and reach
e
similarly evil say no.
This message is not intended for
me.
Now it will again travel onto the
backbone and it will reach the node. There
is f
And F will say yes. This message is
intended for me, and I have successfully received
this message.
So this is how a bus type of network
works wherein a message
travels onto the backbone to each of
the node.
And it has been decided over there that this message
is intended for that node or not based on
Mac address mapping.
so let's move on to the second type that is
the star Network topology
So in this as you can see, there are again.
Computers which are connected which we call as
node. So there is node a node B node C.
Naughty and node e
Which are connected to a centralized hub?
so let's say if a wants to transfer a message to
node d
Then it is going.
To transfer the message through the Hub.
to the node
D directly
and it will
acknowledge that I have received.
The message which was intended to send to
the D.
So
like first Network, it does not happen over
here that the message will go to the each node. It
directly goes to the intended node.
Where the message.
the sender wants to send
perfect.
So, let's see the next type of topology. That is the
ring topology.
Here as you can observe that all the
nodes are connected into a circular form.
Node A B C D E and F are into
a circular ring form therefore giving
this topology the name as ring topology.
So in ring topology, the flow of
data is either in
the form of clockwise or anti-clockwise.
This is decided before making
this topology.
So let's say a wants to transfer the
message.
So the message will transfer from node a
to node B and B will
say okay. This is not intended for me. It will
transfer to c c will say no it is
not intended for me. Then it will finally reach
D and D will receive it
and D will say okay this is intended for me.
So here we saw.
The flow of the data packet was
into one direction that was clockwise Direction.
and its successfully reached the node d
Which was indented to receive the message.
The next type of topology is the hybrid topology.
So it is a combination of all types of topologies.
As you can see into the figure.
There is a star type of connection.
A ring type of connection as well as a burst
type of connection.
so
hybrid is a new type of topology which comprises
of all types of
topology whether it is mixture of
two or more.
These type of topology is implemented into
companies wherein they want to utilize the
features of all the topologies.
but remember implementing a hybrid type of topology can
be very expensive at it
requires the setup of
two or more different types of topologies
also the debugging of hybrid type
of topology can be very difficult.
To find where the fault is as there
will be a lot of interconnection and wiring between
all all the network nodes.
I hope you guys understood the topology. Thank you.
