Meaning, Types & Characteristics of Communication
A self-learning flipbook with examples, recall checks and exam-style practice.
Communication is more than speaking
Communication is the process of conveying or exchanging meaning. It happens when people create, send, interpret and respond to messages.
A spoken message
“The exam begins at 10 a.m.” The words carry the main information.
A silent response
A nod may indicate agreement; a puzzled expression may signal that clarification is needed.
Know the distinctions
Sender vs receiver, encoding vs decoding, channel vs message, and feedback vs noise.
Apply the concept
Identify communication types and barriers from short situations, not just definitions.
Meaning, definition and purpose
In the supplied study material, communication is described as transferring or conveying meaning. It is also explained as passing information between people through previously agreed symbols to produce a response.
Why do people communicate?
1. Inform
Share facts, updates and information needed for decisions.
2. Teach and learn
Explain concepts, develop skills and pass on knowledge.
3. Coordinate
Help individuals or groups work towards a shared goal.
4. Motivate and guide
Clarify expectations, give feedback and reinforce useful behaviour.
5. Build relationships
Express feelings, negotiate meaning and maintain social connections.
6. Preserve culture
Transmit values, customs, stories and shared knowledge.
Check your understanding: Is every message understood exactly as intended?
No. The receiver interprets a message using language, prior knowledge, attitudes and context. Meaning can differ, so feedback and clarification matter.
Follow the message from idea to response
The supplied study material presents a five-stage classroom/general communication process associated with Cole and Chan.
| Term | Meaning in simple words | Example |
|---|---|---|
| Sender / communicator | Starts the communication and forms the message. | A teacher explaining a rule. |
| Encoding | Converting an idea into words, signs, images or gestures. | Choosing a diagram to explain a process. |
| Message | The information, idea or feeling being communicated. | The diagram and explanation. |
| Channel / medium | The route or means used to send the message. | Speech, email, phone, board or video. |
| Receiver | The person or group for whom the message is intended. | Students listening. |
| Decoding | Interpreting the message received. | A student explains the diagram in their own words. |
| Feedback | The receiver’s response, which helps assess understanding. | A question, answer, nod or written response. |
| Noise | Anything that disrupts the message or its interpretation. | Traffic noise, unclear wording or distraction. |
Models to remember
S–R: Stimulus–Response. S–M–C–R: Sender–Message–Channel–Receiver. A fuller interactive view includes feedback and recognises that participants can exchange roles.
Mini-check: What is decoding?
Decoding is the receiver’s interpretation of the message. Encoding is the sender’s conversion of an idea into a communicable form.
Key characteristics of communication
1. It is a process
It involves connected stages and can continue through repeated exchanges.
2. It uses symbols
Words, pictures, signs, gestures and sounds can represent meaning.
3. It is contextual
Place, social roles, culture and the situation influence interpretation.
4. It is relational
The relationship between people affects how a message is expressed and received.
5. It may be verbal or non-verbal
Words are only one way to communicate; posture and facial expressions also matter.
6. It can be two-way
Feedback lets participants check meaning and adjust their messages.
7. It is continuous and pervasive
People communicate across personal, educational, social and professional settings.
8. It can be affected by noise
Physical, psychological, technical or semantic interference may reduce effectiveness.
Context has dimensions
Physical: place and ambience. Social: roles, status and relationships. Cultural: shared norms and assumptions. Psychological: feelings, expectations and state of mind.
Types of communication
Communication can be classified in different ways. In an exam question, first identify the basis of classification.
| Basis | Type | Example / clue |
|---|---|---|
| Number/relationship of participants | Intrapersonal | Self-reflection, inner dialogue, thinking through a decision. |
| Number/relationship of participants | Interpersonal | Conversation between two people; often allows immediate feedback. |
| Participants | Group | A team meeting or a seminar discussion. |
| Audience and medium | Mass communication | Radio, television, newspapers, magazines or films reaching many people. |
| Organisation / setting | Formal | Official meeting, notice, report or institutional email. |
| Organisation / setting | Informal | Casual conversation with friends or colleagues. |
| Direction in an organisation | Downward | Manager gives instructions to staff. |
| Direction in an organisation | Upward | Staff send a report or feedback to a manager. |
| Direction in an organisation | Horizontal / lateral | Colleagues at a similar level coordinate. |
| Channel / mode | Verbal / non-verbal | Words vs gestures, posture, facial expression or other cues. |
What does “intrapersonal” mean?
Communication within oneself, such as reflection or internal dialogue. Do not confuse it with interpersonal communication, which occurs between people.
What is mass communication?
Communication through media capable of reaching large audiences, such as radio, television, newspapers, magazines and films.
Verbal, non-verbal and paralanguage
Uses words
Oral: lectures, interviews, discussions and phone calls. Often immediate and allows quick clarification.
Written: letters, reports, notices, emails and messages. Can be reviewed and retained as a record.
Uses cues other than words
Facial expressions, gestures, posture, eye contact, physical distance and body movement may reinforce or complicate spoken words.
Paralanguage: how the voice sounds
Paralanguage includes features such as pitch, volume, rate/speed and clarity of delivery. The same sentence can sound encouraging, impatient or sarcastic depending on delivery.
Quick compare
| Oral | Written | Non-verbal |
|---|---|---|
| Fast exchange; tone and immediate feedback may help. | Can be edited, stored and revisited; feedback may be delayed. | Can communicate emotion or emphasis; interpretation depends on context and culture. |
Can non-verbal communication contradict words?
Yes. A person may say “I’m listening” while repeatedly looking away. Receivers often interpret the words together with non-verbal cues and context.
Barriers to effective communication
A barrier is anything that prevents a message from being transmitted, received or interpreted as intended. The supplied December 2025 paper’s explanation groups barriers including technical, physical, semantic and psychological barriers.
Physical barriers
Distance, poor room layout, low audibility, interruptions or an unsuitable environment.
Improve: choose a suitable setting, reduce distractions and make the message accessible.
Technical barriers
Device, software, network or platform problems; lack of familiarity with technology.
Improve: test equipment, provide a backup channel and explain how to use the tool.
Semantic / language barriers
Unfamiliar jargon, ambiguous words, different language meanings or unclear phrasing.
Improve: use plain language, define terms, give examples and invite questions.
Psychological barriers
Prejudice, anxiety, lack of interest, defensiveness, inattention or strong emotions.
Improve: listen actively, build trust, check assumptions and allow respectful dialogue.
Cultural barriers
Different norms, expectations, symbols or interpretations of gestures.
Improve: avoid assumptions and check meaning rather than relying on stereotypes.
Knowledge / receiver barriers
The receiver may lack background knowledge or may not understand the language or format used.
Improve: adapt vocabulary, pace and medium to the audience.
Exam scenario: the video lesson keeps freezing. Which barrier?
A technical barrier. If the audio is inaudible because the room is noisy, it is a physical/environmental barrier.
Classroom and mass communication
Classroom communication
Classroom communication supports teaching and learning. Its effectiveness is affected by the teacher, learners, message, teaching method, media and learning environment.
- Use a logical sequence and language suited to learners’ level.
- Combine explanations with examples, diagrams or demonstrations when useful.
- Watch for direct feedback (questions, answers) and indirect feedback (expressions, attention).
- Invite questions and check understanding instead of assuming silence means comprehension.
Mass communication and communication technology
Mass media
Radio, television, newspapers, magazines and films can disseminate messages to large audiences.
Technology
Smartphones, email, online platforms and networks are technologies or channels that enable communication.
SITE stands for?
Satellite Instructional Television Experiment. This acronym appeared as a communication-related question in the supplied January 2025 paper.

Common confusions
| Term A | Not the same as | Remember |
|---|---|---|
| Encoding | Decoding | Encoding creates the communicable form; decoding interprets it. |
| Message | Channel | The message is what is communicated; the channel is how it travels. |
| Feedback | Noise | Feedback is a response; noise interferes with communication. |
| Intrapersonal | Interpersonal | Within oneself vs between people. |
| Semantic barrier | Physical barrier | Meaning/language confusion vs environmental obstruction. |
