In today's technological world,mobile phones have become part and parcel of our lives.But have we ever thought ,when we call someone,how does our call reach the right person sometimes living long distance apart......

But finally I got answer to my question...

I earlier used to think that when we make a call it goes to the cell tower..yes u are guessing it right..the big towers with antennas which you can find on roof tops,shop tops etc..but that is not it ... So here it goes.....

First when we make a call,each handset has a MIN(mobile identification number) andSIM(sim identification number).which is conveyed to the tower along with your call signal ..The tower sends back acknowledgement signal to the mobile..so DUPLEX channel is used..for this transferring ,You must be wondering what DUPLEX channel is??


As name suggest it is a channel,where one path is reserved for sending signal to tower and another path is used to send acknowledgement signal.

Now after your call signal reaches cell tower which is also called BSC..it goes to MSC(mobile switching center) ..MSC actually acts as router or you can say a switch which sends your signal first for verification, ie to VLR( verification location register) which is actually a sub register..

Well let me explain in detail............

When you get prepaid card the carrier company asks you to fill in details..that details goes to a big register called HLR(home location register)..
From there, data is divided according to different region and send to various VLR..so ,from there  MSC checks whether person is at roaming or not..

After that the call is send to the nearest MSC of the person you want to call and from there call is send to the nearest tower of the person you are calling.. And finally call is received...

This is how call reaches from source to destination.....

I hope you guys could understand..This whole call forwarding process I told above  is part of PUBLIC SWITCHED TELEPHONE NETWORK which consist of telephone wires,fibre optics,cables,microwave transmission....And whatever explained above is just like a drop in the ocean..as networking is vast subject and it is not possible to cover each point...

OUR STORY

Taking out the most powerful weapon.Don't worry I'm not taking out bayonet but PEN.But then what should I write about???  I ruminated for few seconds and thought that there couldn't be a better story than that of a PURE 100% Indian Student.


SCENE 1


A child is born and the minute he comes into this world,plans are made,blueprints are approved (in which,every memeber of the family takes par,t except the child) to make him either an engineer or a doctor.As if there are no other options.But, I  think at least let him start speaking so that he could let his emotions out.And see the irony he does display his emotions by CRYING(as if trying to say that can someone ask me too).......


SCENE 2
//PTM IN THE SCHOOL .THE CHILD IS ABOUT TO GET HIS REPORT CARD FOR CLASS IX.//


Fingers crossed,heart beating faster than a speeding Ferrari...What will be my score???Will my teacher complain about me to my mother??? What will my mother say after seeing my report card..The list is endless..
At that time it seems that at any moment whistle of a pressure cooker will blow....But all  worries  were clean bowled when my teacher declared my  result to be 92% and applauds me.I was feeling  on cloud nine, not knowing that this had only exaggerated my dilemma...You must be wondering that why I said dilemma .??? Friends you'll know it as I proceed further........since this was only trailer and picture was yet to be premiered...  :)
The point is when we score good or otherwise  in our junior classes our parents expect us to do well in all the exams we sit in...They think as if, we are the only student sitting in the exam,so obviously we will top....The irony here is that each and every parent thinks this way ,so not one but all go through the same dilemma.For the next few years  till you start earning ,they pamper you just like the witch did in HANSEL AND GRATEL story...and along with the pampering we get to listen a soft music
"
        Dear give your best shot,work harder if you are only working hard..because after that everything would be easy and smooth"


We listen to it so many times that it entrenches deep in our blood..And it actually makes us feel that we say to ourselves, common buddy just one last obstacle and you can be free from cat and mouse race...
                                             BUT IS IT????????


SCENE 3
CLASS X BOARD EXAMS RESULT IS TO BE DECLARED NEXT DAY!!
We go to every church,temple,mosque and not even spare the deity which is meditating peacefully under the tree...At night we keep turning sides ...Next day when we open our computers and type our roll no,our mind works on 10 different paths(What,how,why ,can it ib my result etc etc???).And then the screen open....
OH MY GOD , I got 92%...we do not believe our own eyes ....So now we take a sigh..PHEW!!!!!!
Now we think that our life would be easy,with no routine chit-chat with dad about studies ,marks etc..
Is it really an end??? we students are so naive that we do not understand the he whole blockbluster is still to come.....


SCENE 4
Now we Are  made to choose either medical or non medical…Mind it commerce field is kept out of options..From day 1 till next 730 days we ride on two boats,school and entrance exam..Now with just one month left to the board exams..the only music  we hear is

“

    Dear work hard,just a month is left,give your best becoz after that you’ll get your line and then you can enjoy.

“

In short ,they want to say BHAAG MILKHA BHAAG FINISH LINE IS JUST FEW YARDS AWAY!!!!

SCENE 5

Finally we get admission in a college and are happy..since now we feel we can take a break from cat and mouse race..But friends this is only a kit-kat break..After enjoying 1 or 2 years we are again pushed in the race where our parents want us to top..ie race of getting admission in IIM.The problem is, at each step of our education,and with each result we get, our parents expectations increase …
and we kids try our level best to fulfill it...
sometimes I wonder when will we relax and take a chill pill becoz in todays  hi-tech modern world we are trying every possible oppurtunity we can to climb the success ladder and in the process we are missing the time we should spend with our families....


SCENE 6
Now after 10 years when we our selves become parents,we make the same blueprints as our parents did  for  our child's future  and the whole thing starts again..Irony  is the people who hated when their parents used to bug them about studies ,themselves are making their children walk the same trodden path they once made  to  follow..
But I guess ,Parents think like parents and kids are kids:)
So I salute all the parents as deep inside their heart ,they want our well being which we realise only when we become parents.As only parents can sacrifice or spend their whole lives so that we live a comfortable life...
