Process of Communication

Communication is a continuous cycle. Here’s how it works:

Steps Explained:

1. Sender thinks of an idea (e.g., "It’s getting late").
2. Message is formed (e.g., "Let’s go home").
3. Channel is chosen (e.g., speaking, texting).
4. Receiver gets the message (e.g., a friend hears it).
5. Feedback is given (e.g., "Okay, let’s go").

Example:

• You (sender) say, "Can you pass the salt?" (message) to your friend (receiver) at the table (channel).
• Your friend passes the salt (feedback).

Barriers to Communication

Sometimes, messages don’t reach clearly due to barriers. These can be:

Example:

• If a loud fan is running while someone is speaking, you may miss the message (physical barrier).
• If someone uses slang you don’t understand, you may get confused (semantic barrier).
