What events occur in the system when the data transmission channel capacity limit is reached?

When the data transfer channel's capacity limit is reached, the following events may occur:

• Transmission delays: data begins to transfer more slowly as the channel becomes congested.
• Packet loss: if buffers are full, new packets may be discarded.
• Increased waiting time: processes or goroutines attempting to send data may block or wait for the channel to free up.
• Errors or exceptions: in some systems, an overflow or transmission error notification mechanism may be triggered.

In the context of Go, if the channel is full (for buffered channels), attempting to send data blocks until space is freed, which can lead to goroutine blocking if the consumer does not receive data in time.
