                                   — Kunal Verma

          SUMMARY IN ENGLISH

A small instrument called Mobile has become part and parcel of modern way of life today. It has empowered man to get information at any place and at any time. One always keeps himself connected and thus he is not debarred of information. Short Message service or SMS is a part of global system for mobile communication and it can be sent and received on your mobile, the small instrument which is carried in your pocket easily.
The best part of this is that the message is delivered at the destination even if your mobile is switched off or out of the coverage area. There is a short message Service center [ SMSC ] run by a service provider who stores the message while the mobile is switched off and pushes the message as soon as the mobile gets activated. The receiver gets and alert single to indicate that a message is lending in his Mobile. Then again there is another beauty that even it you are having a talk on your mobile the SMS does not get blocked or is not kept in waiting. This is because, the short message travel over the radio channel used for voice communication. They operate on a separate signalling path and do not come in the way of voice communication. Is it not  something wonderful ?one gets double benifit at the same time, with the the addition of FM radio, digital camera, calculator, world time clock and so many other advantages, a mobile has become a multipurpose instrument. This has brought revolution in the field of personal as well mass communication.
This SMS revolution started from Europe and soon took over the whole world.The first SMS is believed to have been sent in December 1992 from a PC to a mobile phone on the Vodafone GSM network in the United Kingdom.
When  we look back, it gives surprise as to how this revolution in the field  of communication has silently entered into our life.
This story of A Silent Revolution has been written by Kunal Verma and  was published in the Hindustan Times of Patna  edition.

            SUMMARY IN HINDI
मोबाइल नामक एक छोटा-सा यन्त्र आधुनिक जीवन का अभिन्न अंग बन गया है।इस यन्त्र ने मनुष्य को किसी भी स्थान और समय पर सूचना प्राप्ति और प्रदान करने की क्षमता दी है। इसके माध्यम से व्यक्ति सदा अपने को  सूचनाओं से जोड़े रख सकता है और वह अपने -आपको अछूता नहीं पाता है। लघु सन्देश सेवा या एस एम एस, मोबाइल सेवा का ही एक अंग है। यह एक वैश्विक सेवा और सुविधा है और इसका उपयोग कहीं भी और कभी भी हो सकता है। सबसे बड़ी बात है कि यह मोबाइल यन्त्र एक छोटा-सा यन्त्र है जिसे आप अपने पाँकेट या बैग में आसानी से रख सकते हैं।
एस एम एस के माध्यम से भेजा वाला सन्देश अपने गंतव्य पर स्वत: पहुँच जाता है। आपका मोबाइल अगर बन्द है तो भी आपके द्वारा भेजा सन्देश, सेवा प्रदान करने वाले केन्द्र पर आपके मोबाइल के क्रियाशील होने तक प्रतीक्षारत रहता है। जैसे ही आपका मोबाइल जीवन्त हो उठता है, सेवा प्रदान करने वाला  केन्द्र आपके मोबाइल की तरफ उस सन्देश को संचलित कर देता है। सन्देश को संचरित कर देता है। सन्देश प्राप्तकर्ता को एक सिग्नल द्वारा सन्देश के आगमन की पूर्व सूचना भी दी जाती है ताकि वह सचेत हो जाय।
इस लघु सन्देश सेवा की अगर अपने मोबाइल पर सन्देश प्राप्ति के दौरान किसी व्यक्ति से वार्तालाप कर रहे होते हैं, उस स्थती  में लघु सन्देश मार्ग में अवरुद्घ नहीं हो जाता या उसे प्रतीक्षारत नहीं रहना पड़ता । इसका कारण यह है कि वार्तालाप हेतु मोबाइल एक रेडियो तरंग ज्का उपयोग करता है जबकि एस एम एस के सिग्नल संचरण हेतु एक अलग सिग्नल मार्ग का उपयोग करते हैं। इससे आपके वार्तालाप में व्यवधान नहीं उपस्थित होता ।
आज  का मोबाइल अब बहुउद्देशीय हो रहा है। इसमें एफ एम रेडिओ, डिजीटल कैमरा, कैलकुलेटर, विश्व के देशों के स्थानीय समय जानने  की सुविधा उपलब्ध हो रही है। इसने व्यक्तिगत संचार और लोग संचार (mass communication) की दुनिया में क्रान्ति ला दी है।
जब पीछे मुड़कर देखते हैं तो आश्चर्यचकित रह जाते हैं कि कैसे दबे पाँव से इस अदभुत आविष्कार ने हमारे जीवन में प्रवेश किया । एस एम एस क्रान्ति का सूत्रपात दिसंबर 1992में युरोप में हुआ था जब लिखित एस  एम एस [लघु संदेश] वोडाफोन नेटवर्क के माध्यम से एक मोबाइल पर भेजा गया था।

The beauty of SMS is that message can be sent and received even while making voice calls. This is possible because a voice call take over a dedicated radio channel for the duration of the call, while the short message travel over and above the radio channel using the signalling path.
एस एम एस की सबसे बड़ी विशेषता यह है कि उसके माध्यम से वार्तालाप के दौरान भी संदेश भेजें और प्राप्त किये  जा सकते हैं।
ऐसा इसलिए संभव हो पाता है क्योंकि वार्तालाप एक निर्धारित रेडियो तरंग पर संचरित होता रहता है जबकि एस एम एस उस दौरान अपने निर्धारित (सिग्नलिंग पाथ) पर यात्रा करता है जिसका आकाशीय विद्युत पथ , रेडियो तरंग से अलग होता है।
