A Silent Revolution Summary
Short Messaging Service or SMS was started to aid the Global System for Mobile Communication or GSM. SMS gives users the ability to send and receive alphanumeric messages on their mobile phones. SMS, like e-mail, can be stored in the Short Messaging Service Centre or SMSC. It is forwarded to the destination mobile phone when the gateway allows movement. The movement is allowed when the destination mobile phone finally connects to the internet. SMS can be sent while making voice calls because a voice call occupies a radio channel, but SMS travels over and above the radio channel using the signalling path. While it is usually immediate, it can be delayed due to congestion. Unlike Instant Messaging Service, the sender and receiver cannot send a message simultaneously. The history of the SMS technology was slow and sleepy because cellular operators did not believe in the potential of the technology. However, now every cellular operator and mobile manufacturer is using the technology to the fullest. Developers are now preparing Multimedia Messaging Service or MMS from it. Nokia recently launched a handset that can send Hindi SMS messages.
Summary of the Lesson A Silent Revolution in Hindi
शॉर्ट मैसेजिंग सर्विस (एसएमएस) की शुरुआत ग्लोबल सिस्टम फॉर मोबाइल कम्युनिकेशन (जीएसएम) की सहायता के लिए की गई थी। एसएमएस उपयोगकर्ताओं को मोबाइल फोन पर अल्फ़ान्यूमेरिक संदेश भेजने और प्राप्त करने की सुविधा देता है। ईमेल की तरह, एसएमएस को शॉर्ट मैसेजिंग सर्विस सेंटर (एसएमएससी) में संग्रहीत किया जा सकता है। गेटवे द्वारा संचार की अनुमति मिलने पर इसे गंतव्य मोबाइल फोन पर भेज दिया जाता है। जब गंतव्य मोबाइल फोन इंटरनेट से कनेक्ट हो जाता है, तभी संदेश भेजने की अनुमति मिलती है। वॉयस कॉल करते समय एसएमएस भेजा जा सकता है क्योंकि वॉयस कॉल एक रेडियो चैनल का उपयोग करती है, जबकि एसएमएस सिग्नलिंग पथ का उपयोग करके रेडियो चैनल के ऊपर से गुजरता है। हालांकि यह आमतौर पर तुरंत पहुंच जाता है, लेकिन भीड़भाड़ के कारण इसमें देरी हो सकती है। इंस्टेंट मैसेजिंग सर्विस के विपरीत, प्रेषक और प्राप्तकर्ता एक साथ संदेश नहीं भेज सकते। एसएमएस तकनीक का इतिहास धीमा और सुस्त रहा क्योंकि सेलुलर ऑपरेटरों को इस तकनीक की क्षमता पर भरोसा नहीं था। हालांकि, अब हर सेलुलर ऑपरेटर और मोबाइल निर्माता इस तकनीक का भरपूर उपयोग कर रहा है। डेवलपर्स अब इससे मल्टीमीडिया मैसेजिंग सर्विस (एमएमएस) तैयार कर रहे हैं। नोकिया ने हाल ही में एक ऐसा हैंडसेट लॉन्च किया है जो हिंदी एसएमएस संदेश भेज सकता है।
Theme of the Lesson A Silent Revolution
This chapter shows the power of innovation. Modern technology is a powerful tool that can help in modernisation and globalisation in various fields. In this chapter, we see an advancement in communication via modern technology. We also see how innovation is not always readily accepted, as evidenced by the slow start of SMS technology due to disinterest from cellular operators. We also see how one technology leads to another, like how SMS led to MMS technology.
A Silent Revolution Lesson Explanation
Passage: Short Messaging Service or SMS was conceived as a part of the Global System for Mobile Communication (GSM) digital standard. It is the ability to send and receive text massages (alphanumeric) at a mobile phone. SMS, like e-mail, is a store and forward service that utilizes gateways to send messages from senders to the recipients.
Word-meanings:
conceived: imagined, thought
alphanumeric: containing both letters and numbers
recipient: person who receives something
Explanations: Short Messaging Service or SMS was developed as a part of the Global System for Mobile Communication or GSM. The SMS is the ability to send and receive messages containing both letters and numbers at a mobile phone. SMS is similar to email, as it can be stored and forwarded via gateways. There is a sender and a receiver.
Passage: However, messages are not sent directly from the sender to the receiver but are routed through a Short Messaging Service Centre, (SMSC) run by the service provider. This ensures that the message is delivered at the destination mobile even if it is switched off or out of the coverage area. The SMSC stores the message and forwards it when the mobile is switched on or enters the network. Normally, messages are delivered instantly but at times there can be delay of some hours due to congestion.
Word-meanings:
congestion: traffic
Explanation: Messages are not sent directly from the sender to the receiver. There is a Short Messaging Service Centre or SMSC run by the service provider that ensures that the message is delivered at the destination mobile even if it is switched off or out of the coverage area. When the destination device comes online, the SMSC will forward the stored message to the device. Congestion can delay the delivery of messages.
Passage: The beauty of SMS is that messages can be sent and received even while making voice calls. This is possible because a voice call takes over a dedicated radio channel for the duration of the call, while the short messages travel over and above the radio channel using the signalling path.
Explanation: SMS can be sent while making voice calls because a voice call occupies a radio channel, but SMS travels over and above the radio channel using the signalling path.
Passage: The process of sending messages and reading them generally varies from handset to handset. However, confirmation of message delivery is immediate and there is always an alert signal to convey the arrival of a message.
Word-meanings:
handset: handheld gadget
Explanation: The process of sending messages and reading them varies in different mobile phones. Confirmation of message delivery is immediate. When a message arrives, there is an alert on the screen and a sound to convey the arrival of a message.
Passage: SMS messages are immediate but not simultaneous like the Instant Messaging Service, which allows virtual real time text conversations with people who are simultaneously logged on to the Internet.
Word-meanings:
simultaneous: occurring or operating at the same time
Explanation: SMS are fast, but the sender and receiver cannot send messages at the same time as they can with the Instant Messaging Service.
Passage: Access to SMS is generally free and a beginner has only to register the network service centre into his/her handset. The message service centre number for BSNL is +919434099997.
Word-meanings:
access: way of approach or entry, admittance
Explanation: SMS can be accessed free of cost and by registering the network service centre into the handset. The helpline number for BSNL service provider is given as +919434099997.
Passage: The launch of SMS opened a new vista in the field of text communication, providing a new easy way to the people to communicate. The limitation of characters (160 for the GSM networks at present) or the tedious process of typing from the small handset keypads failed to deter the spirit of the enthusiasts. The SMS revolution that took roots in Europe slowly spread to other parts of the globe, especially Asia. From the first short message, believed to have been sent in December 1992 from a PC to a mobile phone on the Vodafone GSM network in the UK, SMS has come a long way today.
Word-meanings:
vista: long narrow view as between rows of trees, mental view of a long series of even
tedious: tiresomely long, wearisome
deter: discourage or prevent, especially from fear
Explanation: SMS opened a new series of communication in the field of text communication. It was a new and easy way to communicate. The characters are sometimes limited, but this con did not discourage people from using this method of communication. The first SMS was sent in December 1992 from a PC to a mobile phone on the Vodafone GSM network in the UK. The SMS revolution first started in Europe and slowly spread to Asia.
Passage: Judging by its success, at present not many would believe that SMS had a very silent beginning. Not even the cellular operators could comprehend the potential of this sleepy technology initially and cared little to advertise it as an attraction for mobile users. However, all that is history now. Today every market player, from cellular operators to mobile handset manufactures, is keen to capture its share of the pie. Nokia recently launched the first Hindi compatible handsets 3350, to give its users the option of sending messages in Hindi.
Word-meanings:
comprehend: understand
compatible: able to coexist, well suited
Explanation: SMS had a silent beginning because initially, cellular operators could not understand the potential of the technology and did not advertise it. However, now every cellular operator and mobile manufacturer is keen to utilise the technology. Nokia has now launched the first Hindi compatible handsets 3350 for Hindi SMS messages.
Passage: Buoyed by the success of SMS, the industry is now preparing for the more advanced MMS or multi-media messaging service, which would enable pictures, sounds and longer formatted texts to be sent to other MMS-enabled terminals or e-mail addresses via the mobile.
Word-meanings:
buoyed: encouraged
Explanation: The SMS technology was so successful that it encouraged the development of MMS, or Multimedia Messaging Service. MMS allowed users to send and receive pictures, sounds and longer formatted texts.
