It is better than udp but due to these features it has an additional overhead. Udp q tcp q header format, connection management, checksum q congestion control q. By using sequence numbers and acknowledgment messages, tcp can provide a sending node with delivery information about packets transmitted to a destination node. In other words, whether youre sending a packet via tcp or udp, that packet is sent to an ip address. For cics users who might be more accustomed to sna, the left side of figure 1 shows the sna. Here is a quick reference chart describing the differences between tcp and udp. User datagram protocol udp connectionless both tcp and udp provide a mechanism to differentiate applications running on the same host, through the use of port numbers.
