Final answer:
The type of communication where sender and receiver are actively engaged at the same time is synchronous communication, which allows for immediate feedback.
Step-by-step explanation:
The type of communication that occurs when the sender and receiver are concurrently engaged in the communication process is known as synchronous communication. This simultaneous interaction can take place in various forms, such as face-to-face conversations, telephone calls, video conferences, or online chats. Synchronous communication allows for immediate feedback and clarification, making it a dynamic form of communication. In contrast, asynchronous communication, such as emails or forum postings, happens when the parties are not communicating in real-time. To ensure effective synchronous communication, especially in professional settings, it's essential to avoid jargon and articulate clearly to prevent misunderstandings.
