The client will confirm reception of the segments and will notify the server if data is missing
  1. Client sends synchronise (SYN) message to the server containing a random number (N)
  2. Server replies to the client with a message containing an acknowledgement (ACK) set to N + 1. Server also adds another SYN value equal to a random number (M)
  3. Client in turn sends an acknowledgement message with value set to M+1. Yes, introductions on the Internet are weird
TCP three-way handshake
