INTRODUCTION TO COMPUTER NETWORKS: Networking tutorials for beginners 1 Video Lecture | Basics of Computer Networking (English) - Basic Technology

hello hello hello welcome to effect
know.com video tutorials and today we
are going to discuss about computer
networking guys and girls this is
tutorial number one and we are going to
discuss what do we mean by computer
networking if you ask me what is a
computer network my answer would be that
if you join together a bunch of
computers then you have got a computer
network when I talk about computers then
I mean desktop computers you are laptop
a tablet PC computer your mobile phone
can be a part of that computer network
your printer can be a part of that
computer network your Smart TV can be a
part of that computer network and your
kin consoles for example your Xbox or
Playstation can be a part of or computer
network and all these devices which are
a part of computer network are called
nodes these are all nodes of canary
nodes of the computer network so guys
and girls we need two things for
computer networks computers and some
medium to join those computers so this
medium is called communication medium
so we can use different types of
communication media to join computer
networks and the most common being
cables or should I say copper cables
networking cables are used to join
computers into a network we can also use
fiber optics to join computers together
and nowadays Wi-Fi or wireless
technologies or values medium is
becoming very common to join to make
computer networks we can use Wi-Fi or
WiMAX to make computer networks we can
use satellite technology to make
computer networks we can use mobile
technology to use computer to create
computer networks we can create
component networks with the help of
microwaves or radio waves sectoral
sector so these are the examples of most
common medium that is used to create
computer network this is called a
communication media so guys and girls
you would be asking yourself why do we
need to create or develop computer
network what is the purpose of computer
networks simple answer is the data and
resource shared
so guys and girls what do I mean by data
data may be you are documents and an
example of data is picture images
another example is videos for example
videos on YouTube this video tutorial
and all the things which you share on
internet are examples of data so we need
computer networks or we need networks to
share data among different devices and
the second purpose of computer networks
is resource share so what do I mean by
with so sharing let us suppose we have
got three computers but we have got only
one printer so now we can connect
printer with one of the computers and we
can connect the other two computers with
the computer which is connected to our
printer and then we can all share the
resource this is those which is printer
among all the three computers which is
which are the part of computer networks
another example of resew seeing is the
internet connection let us suppose we
have got our laptop a tablet and a smart
TV at home but we have got only one
internet connection and usually we at
home and usually
we share the internet connection
resource one internet connection
resource went three devices so the
purpose of computer network is to share
the resources and to share the data so
thank you very much guys and girls for
joining me for I fetch know.com video
tutorial since you can read more about
computer networks on my website
ifactner.com in the next tutorial we
will be discussing about the types of
computer networks and those types are
LAN man and when so guys and girls see
you in the next tutorial until then take
care
bye bye
