5. What is visual communication?

message through images or pictures alone. The main advantage of this type of communication is that you don't

B. Long answer type questions.
1. What are phonetics? Explain in detail.
Ans. Phonetics is the study of human sounds and phonology is the systematic classification of sounds in one or more
specific languages. Sounds can be divided into consonants and vowels. The first can be characterized by 1) place, 2)
mode of pronunciation and 3) voice. The English alphabet has 26 letters from A to Z. However, each of these letters
can be pronounced differently in different words. We write words in English language using 26 letters. However,
while speaking English, more than 26 sounds are used. For this reason, the spelling of a word does not always
match its pronunciation.
2. What are greetings? Define two types of greetings.
Ans. There are many ways to greet when you meet someone. Greetings differ when you meet your colleagues at work or
meet friends. Similarly, there are many ways to say goodbye when leaving for the day. Greeting also depends on who
we are talking to and even the time of the day. Overall, greetings help us start a nice conversation.
There are two methods of greetings as follows:
Formal Greetings: You formally greet someone if you do not know the person. It is used to greet an elderly person,
or people with whom we have a formal relationship such as a teacher or a client. This is used more often in schools,
colleges, offices, meetings, etc.
Informal Greetings: Informal greetings are used when you are talking to friends, family or when you know the
person very well.
3. What is verbal communication? Write any three advantages of it.
Ans. Verbal communication is the exchange of information using words. This is what most people use as a communication
method. Verbal communication is important. If you don't use the right words, you'll be confused and you won't be
able to convey your message.
The three advantages of verbal communication are:
• Saves a lot of time and money.
• This mode of communication is convenient to use since it is quick in obtaining feedback from receiver.
• In case of written communication, the information conveyed can be saved for future use such as for production
of evidence.
