This is the basic description of the Distributed Coordination Function (DCF) used in the IEEE 802.11 wireless LAN standard. The sender (i.e., the station wishing to transmit data) follows a set of rules to avoid collisions with other stations trying to access the same medium. One of these rules is to wait for an ACK packet from the receiver (i.e., the station that successfully received the data) before sending more packets. This helps ensure reliable communication and efficient use of the channel.
