The name of the switching feature that prevents frame dropping in case of congestion by pausing sending frames is called Flow controlWhat does "flow control" mean?The management of data flow between computers, devices, or network nodes is known as flow control. This allows the data to be processed at an effective rate. Data overflow, which occurs when a device receives too much data before it can handle it, results in data loss or retransmission.Therefore, By controlling network flows to prevent frames from being dropped during times of congestion, flow control provides lossless transmission. On a full-duplex Ethernet physical link, flow control can pause and resume the transmission of network traffic between two connected peer nodes.Learn more about Flow control fromhttps://brainly.com/question/12908248#SPJ1
