What mechanism is used by the tcp to provide flow control?

TCP uses a mechanism called sliding window for flow control. This method allows the sender to send multiple packets before needing an acknowledgment for the first one, thus optimizing the use of available bandwidth. The size of the window can adjust dynamically based on the receiver's buffer capacity, which helps prevent overflow and ensures that the sender doesn't overwhelm the receiver with too much data at once. This coordination helps maintain efficient data transmission and avoids congestion in the network.
