C. 1. LONG ANSWER QUESTIONS

Q. 1. How has SMS brought about a silent revolution?

Ans. SMS, conceived as part of the GSM digital standard, has rapidly spread across countries as a swift means of communication. Its unique feature allows messages to be sent and received even during voice calls. The widespread demand and utilization of SMS have ushered in a silent revolution in global communication, marking a significant transformation in the field.

Q. 2. How do you think that SMS has now become the most preferred option for communication?

Ans. SMS possesses the ability to send and receive text messages on mobile phones, operating as a store-and-forward service using gateways. This feature, along with the convenience of sending messages during voice calls, distinguishes SMS from other communication methods. These attributes contribute to SMS being recognized as the most preferred option for communication.

Ans. SMS employs SMSC to route messages, allowing delivery even when the recipient's mobile is switched off or out of coverage. Additionally, SMS is generally free to access. In contrast, a voice call occupies a dedicated radio channel for the entire call duration, while SMS travels separately above the radio channel via the signalling path. This distinction sets voice calls apart from SMS.

Ans. The introduction of SMS has created a new perspective in communication, offering an effortless way for people to connect. Despite limitations on character count, particularly in current GSM networks, and the challenge of typing on small handset keypads, the enthusiasm for SMS remains undeterred. The launch of SMS has undeniably expanded the possibilities in text communication, providing a convenient and innovative means of connecting with others.

C. 1. GROUP DISCUSSION:

Discuss the following in groups or pairs:

Q. 1. With the introduction of SMS and E-mail writing a message on paper (letter writing) and sending it to others has come down. Do you agree?

Ans. Yes, we agree with it. With the introduction of SMS and E-mail writing a message on paper (letter writing) and sending it to others has come down. As we think the paper writing is going towards its end. It is only used as an official while the letters of appointment, joining, notice etc. are send to the said persons. Generally, now people communicate to others on SMS or e-mail.

Q. 2. The current phase of rapidly changing world conditions is a good sign or a bad sign for humanity.

Ans. As, I think the current phase of rapidly changing world conditions is not a good sign. The beginning of SMS and launch of mobile cellular phones has polluted the Global environment. The ultra-violet rays form the mobiles affect the human. As I listen more users of mobile phones may lose their brain capacity and brain hammarites may be occurred. It is not a good sign for humanity.

C. 3. COMPOSITION

Q. 1. Write a paragraph in about 80 words on each of the following:

(a) The mobile as a companion

Ans. At present mobile is a good companion of a human. There are many kinds of things in the mobile. We can not only talk or can send one messages to others but if we are in alone, we can use a mobile as playing games, using to listen songs etc. If we are to measure or calculate a numerical problem, calculator is available in mobile sets which help us to calculate the problems. We have no need of any watch to know the time because it is available in mobile sets. We can use alarm clocks to a work at said time. Thus, we see that the mobiles much close to us and sometimes we do not need company of mobiles are our hands.

This was an easy decision. It is, however, a decision that we had to take. Sometimes we use 'however before an adverb or adjective to emphasize that the degree or extent of something cannot change a situation. However fast he ran, he failed to win.

G. TRANSLATION

Translate into Hindi your mother tongue.

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.

"SMS की सुंदरता यह है कि संदेश वाणी कॉल करते समय भी भेजे और प्राप्त किए जा सकते हैं। यह इसलिए संभव है क्योंकि वाणी कॉल आदर्श रेडियो चैनल पर कॉल के समय कब्जा करता है, जबकि छोटे संदेश रेडियो चैनल के ऊपर और उसका सिग्नेलिंग पथ का उपयोग करके चलते हैं।"
