The correct answer is option 3.

Concept:

Switching techniques There may be multiple paths from sender to receiver in large networks. The switching technique will determine the best data transmission path. The switching technique is used to connect systems in order to perform one-to-one communication.

Circuit Switching:

Circuit switching is a switching method that creates a dedicated path between the sender and the receiver. In the public telephone network, circuit switching is used. It is used to transmit voice.

When a user wishes to send data, voice, or video using the circuit switching technique, a request signal is sent to the receiver, and the receiver responds with an acknowledgment to ensure the availability of the dedicated path. The data is transferred via the dedicated path once the acknowledgment is received.

Packet switching:

Packet switching is a switching technique in which the message is divided into smaller pieces and sent individually rather than all at once. Packet Switching services are suitable for establishing internet service.

Packet switching is used to optimize the use of available channel capacity in digital telecommunication networks, such as computer networks, as well as to reduce transmission latency and increase communication robustness.

Message Switching:

Message switching is a switching technique that transfers a message as a complete unit and routes it through intermediate nodes where it is stored and forwarded.

Hence the correct answer is (i) Circuit switching, (ii) Packet switching.

Read the passage carefully and select the best answer to each question out of the given four alternatives.
Public opinion may be passive and false or active and real. It is claimed in theory that all governments are ultimately based on the opinion or sanction of the governed. But we find that in practice the people's rights are often trodden down and tyranny and oppression are allowed to continue. The government does it not because the people want it to do so but because they are too idle, too uneducated and too disunited or timid to oppose the govern ment. Such public opinion is passive and false and not an active verdict. But when we find people alert, intelligent and determined to let the government know their will, when they want to exercise actively their voice in the management of their country, we have an instance of true or active public opinion. True public opinion is formed by and expressed through the press, the platform, political parties and educational institutions. These have sacred duties to perform, duties on which depends the ultimate good of the entire community. The press today wields a tremendous influence, So it should support the causes and move ments and condemn the wrong one's and thus teach people to form correct opinion. A free and fair press ventilates the grievances of the public. Thus a healthy relationship develops between the people and the government through out an unbiased press. Political parties also help to create and regulate opinions. No less important part is played by the educational Institutions which train the minds of the young people who will be the citizens of tomorrow. It has been said that modern Germany and China have been made by their universities. It is necessary that the young and the growing minds should imbibe the spirit of fellow-feeling, the spirit of tolerance, the habit of compromise, and show due regard for the feelings and opinion of others without which a democratic society cannot function, let alone succeed. When there is true awakening of the people, we shall have the real and conscious public opinion. And justice will reign on earth and truly will the voice of the people be the voice of God.
According to the passage, which of the following is needed from the people to have true or active public opinion? 1. Alertness
2. Determination
3. Intelligence
4. Raising their voice
