9.  What are closed-ended questions?
                Ans.  Closed-ended questions are those that can usually be answered with a simple "yes" or "no" or with a specific piece of
                    information. They often have a straightforward answer and the answer options are limited or closed.

                  1.   What are basic elements of communication? Explain them.
                Ans.  The basic elements of communication are:
                    •  Sender: The sender sends a message either in the form of giving information or asking for information. The sender
                      can be any person, group or an organisation who initiates the process of communication. The sender's knowledge,
                      experiences and skills influence the quality of the message.
                    •  Ideas/Messages: This message can be in the form of an idea or any information a sender wishes to convey or asking for
                      information from the receiver.

                    •  Communication Channel: It is the medium through which a message can be sent. It can be through oral, written or
                      visual methods. These days, technology plays an important role in serving as an important medium of transmission of
                      information so we can send through email, voice mail, social websites, etc.
                    •  Receiver: A receiver can be any person, group or an organisation who interprets the message conveyed by a sender. The
                      receiver has to extract the meaning from the text, signs or symbols sent by the sender and find out its actual meaning.
                    •  Feedback: It is the receiver's acknowledgement and response to the message for ensuring that they understood each
                      other correctly.
