Which mechanism does the Transport Layer use to prevent data overflow at the receiver’s end?

Question

Accepted Answer

Flow control - The Transport Layer uses a technique called flow control to prevent the receiver from getting too much data at once.

Flow control manages the rate of data transmission between the sender and receiver. This is important because the sender might send data faster than the receiver can process it. If there is no control, it can cause data loss or overflow at the receiver’s end.

In protocols like TCP (Transmission Control Protocol), flow control is done using a sliding window mechanism. This allows the receiver to tell the sender how much data it can handle at a time. Based on this, the sender adjusts the amount of data it sends.

This makes the communication reliable and prevents system crashes or network congestion caused by data overload.

Conclusion: The correct answer is Flow control. It is the key mechanism used by the Transport Layer to avoid data overflow and ensure smooth communication between devices.
