I am Imran Rafai, your trainer for this entire series.

Today we would be starting with network fundamentals

and when I say fundamentals we would deal with the

only for the people who are going for the CCNA certification but

anybody who's interested to, OR looking to start a career

in networking feel free to watch this because you

are going to learn as lot. But CCMA as a certification, is a very valuable

certification and I urge everybody to go ahead and

take that certification because it is gonna add a lot of value.

everybody to concentrate on the first three days

of your entire networking career, maybe even twenty years from now.

be clear with every concept we cover here.

And in case you still have doubts please feel free to email me

us get into the video. Let's start with the

well when I asked this question to my students

more often than not I get answers like Facebook

Twitter Picasa whatever whatever you see on the screen but

well that is social network, that's not the network we are here to learn

and that definitely is not the network I am going to talk about

this network the network between computers

well this network is also the foundation or the base on which

applications like Twitter Facebook picassa

this network and maybe if we have time over the course of this

this series, we will talk a little bit about those

applications here and there. While preparing for this

I was preparing this a image that you see on the screen and I was thinking

okay let me see how to explain this concept

how do I explain this concept without actually using a lot of technical terms

Or saying -  'okay this thing communicates with that

thing over this thing' - I mean it was difficult

and then I thought okay I need a better way to explain this and I i remember the

story that a teacher of mine told me when she taught me

the olden days of how Kings exchanged messages with

to a messenger who used to ride on ha specs

and this go through all these number the peep

pot along the road and in the is to go through this did the city gate and then

this go to other King and deliver the message

so if you compare that to computer network

so the message is like the detail that you send in the data could be anything

doc file a Word document or it could be an excel file it could be any major

could be you BDO it could be anything that detail

and abroad on which the the messenger traveled

that that basically is the network course

computer network has much more interesting than just paving

if you if you see backed is the very pleasing my computer netbook is

invented to communicate between computers

if you see this image you would see let me just take a

a highlighter you will see that we have the Windows PC

and we have laptop more bite for on palm top

you have bebe so is maybe it's running on saint always him database server

in spite of the all running on different operating systems

they all can communicate absolutely perfectly with each other

a global standard called or same orders sand and

and things like that which defines clearly what

when any manufacture manufactures its a networking device

what time how they should communicate with each other

and backed enables them to communicate with each other

let's try to break this a little more further and see

so if you look at the picture on your screens

to computers connected with the wire in this case we will use

a catfight cable a cap to keep a look something like this:

and this has becoming different colors you have

blue-collar ones red color ones from and this is this obviously another color

and this the out a Kabul is just a protective layer

these keep it going to a connector called RG fortify keep it

that looks something like this that you see on the screen and back of your
