Each node is defined by an IP address and a TCP port number. Data is then transferred in segments usually delineated by the maximum transmission unit (MTU) of the data link layer. TCP assigns each packet a sequence number, which is used to make sure each packet is delivered, and in the correct order.

IPv4 Packet Structure. In TCP/IPv4 packets, there is a TCP (or UDP) packet header, then an IPv4 packet header, then the packet data. Each header is a structured collection of data, including things such as the IPv4 source address (who sent the packet), and the IPv4 destination address (who it was sent to). Each packet's header will contain the proper protocols, the originating address (the IP address of your computer), the destination address (the IP address of the computer where you are sending the e-mail) and the packet number (1, 2, 3 or 4 since there are 4 packets).
