Outlines
π Introduction to Subnetting in Computer Networks
In this introductory video, Vikram from Learning Monkey begins by welcoming viewers to a class on subnetting. He suggests watching previous videos for better understanding and encourages following the entire course, which is part of a larger playlist. The concept of subnetting is introduced as the division of a single large network into multiple smaller networks. Vikram explains the different classes of addressing (Class A, B, C) and how they determine the number of systems that can be connected in a network. He uses the example of a university with different departments needing to connect varying numbers of systems, highlighting the need for subnetting due to different technological requirements and network topologies. The video sets the stage for further exploration of subnetting in subsequent classes.
π’ Engaging with the Learning Monkey Community

Highlights
Introduction to subnetting in computer networks.
Subnetting is dividing a large network into multiple smaller networks.
Different classes of addressing in networking: Class A, B, and C.
Class A can configure 16 million systems, Class B can configure 65,000 systems, and Class C can configure 256 systems.
The need for subnetting arises from practical challenges in network construction.
Example of constructing a network for different departments in a university.
CSC, EC, Mechanical, and Civil departments each wanting to connect 60 systems.
Different technologies required for different departments' networks.
CSC prefers Ethernet, EC and Mechanical prefer Ring topology, and Civil prefers Bus topology.
Subnetting allows for the use of different technologies in a single network.
Location of departments as a factor in subnetting decisions.
Departments are scattered throughout the university, necessitating subnetting for connectivity.
Subnetting addresses security, maintenance, and other issues in network establishment.
Subnetting divides a single network into smaller, more manageable networks.
Further understanding of how to divide a network into subnets will be covered in later classes.
Encouragement to subscribe to the channel and engage with the content.

hi welcome to learning monkey i am
vikram in this class we'll try to
understand what is subnetting in
computer networks please watch our
previous videos for better understanding
and every video in our channel is going
to be part of enter course or a playlist
our suggestion is to follow the entire
course so that you can have a better
understanding of the concepts and the
link for the playlist is provided in the
description below now what is meant by
subnetting subnetting is a process of
dividing a single large network into
multiple small networks as we have
discussed that there are different
classes of addressing like class a class
b classy and each class provides its own
way of connecting the systems for
example if you take class a in a class a
address one single address can
configure 16 million systems similarly
if you take class b 65000 systems can be
configured in one single network in the
same way
class c addressing is going to configure
is it is capable of configuring 256
systems so as we have
the possibility of different combination
of networks why we need to do the sub
networking sub networking in the sense
why we need
to divide that single network into
multiple smaller smaller networks what
is the need of subnetting
there are different challenge in
practice whenever we want to construct
the network in
in practice there are different
challenges that are that that we are
going to face while constructing the
networks so what are those challenges
there are different challenges to
understand those challenges we will
consider this example of constructing a
network for these departments in a
university let's consider a university
in that university consider these
departments so csc wants to connect 60
systems ec wants to connect 60 different
hosts not systems means systems means
not only computers 60s hosts and
mechanical wants to construct a lab with
60 hosts and she will also construct
wants to construct a lab with 60 systems
so in that case
so in this case of establishing labs for
these departments what are the different
challenges that we are going to face
different technologies why we need
subnetting is one of the reason is
different technologies so this 60 60 60
means they are around 256 systems so to
establish a network of 250 systems one
single network is sufficient but
what happens here is for example if you
take csc department it wants the the lab
the equipment in the lab wants to
establish their network
uh in a
ethernet network assume that it wants to
create uh the lab in ethernet similarly
if you take
uh
easy lab it wants to establish their
network in
ring topology in ring technology
and similarly if you take mechanical it
also wants to establish their lab in
ringtone
ring technology and
civil it wants to establish its lab in
ethernet means
using the bus topology it wants to
establish and it wants to use the
technology ethernet technology in that
case different networks different
network technologies because there may
be requirement for some of the equipment
that is used in the ec lab to establish
in order for the communication to happen
it may require ring topology or ring
technology
for communication to happen in csc lab
it may require ethernet technology so
based upon those requirements
different technologies are required
to be constructed in one single network
which is not possible so
there is there is a
possibility for us to do subnetting
okay so other reason is location of
lands so for example if you take this
land and csc is located somewhere else
and the department ec will also get
located so they are scattered throughout
the university
okay so in that case in that case so uh
there is a need for us to create
subnetting sub networking security
issues maintenance issues so there are
lots of different issues that are there
in establishing a single network so in
that cases
we are going to consider the concept of
subnetting using subnetting we can
divide a single network into smaller
smaller networks okay so this is what we
call it as subnetting how to divide
a network into subnets that we will try
to understand in our later class hope
you got the clarity on this concept
