Is required to assure that the source does not overwhelm the destination by sending data faster than they can be processed?

Yes, it is essential to ensure that the source does not overwhelm the destination by sending data faster than it can be processed. This can lead to data loss, increased latency, and system overloads. Implementing flow control mechanisms, such as buffering and acknowledgment signals, can help manage the data transmission rate, ensuring smooth and efficient communication between the source and destination. Effective congestion control strategies are also crucial to maintaining system stability.
