TCP/IP Communication implementation

The IP protocol of the network layer provides unreliable communication services. The TCP protocol solves the problem of retransmission and sorting of packets. TCP Communication features: 1) full duplex, simultaneous send and receive data 2) only support two ports between communication 3) based on byte stream. The peer cannot know the bounds of the message. For example, send 4 512 bytes of data, the receiver is not clear is 4 512 or 2 1024
