Oral and written communication are two primary methods of conveying information. Below are the key differences between them:
Step 1: Nature of Communication. 
  
- Oral Communication involves speaking and listening, such as conversations, phone calls, meetings, etc.  
- Written Communication involves writing and reading, such as letters, reports, emails, and other documents. 
Step 2: Speed and Clarity. 
  
- Oral Communication is faster as it allows immediate feedback, but may lack clarity due to the lack of a written record.  
- Written Communication is slower, but it provides a clear, permanent record of the message, which can be referred back to later. 
Step 3: Formality and Permanence. 
  
- Oral Communication is usually less formal, and is less permanent unless recorded.  
- Written Communication is often more formal and permanent, especially in legal and official contexts. 
Step 4: Risk of Misunderstanding. 
  
- Oral Communication may lead to misunderstandings due to language barriers, tone, or lack of clarity in the spoken word.  
- Written Communication reduces the risk of misunderstandings, as the message is clear and can be revisited.
