TCP is a stream protocol. You will need to split the stream up into messages. Two common ways to do that for textual data are to insert particular bytes as delimiters, or prepend each message with its length.

You do not need to know about the packet level protocol, TCP implementations hide that from you – from a programming point of view a TCP connection is a stream (well, an input and and output stream).

Protocol is named TCP, Transmission Control Protocol, see for more detail: http://en.wikipedia.org/wiki/Transmission_Control_Protocol[^].

It will work for your chat application. To get some ideas, look at my past answers.

This is a skeleton design of server with threads serving multiple remote sockets:
Multple clients from same port Number[^].

You can use TCP on several different levels, see:
how i can send byte[] to other pc[^],
Communication b/w two Windows applications on LAN.[^].

With v.2.0, you can use them all up to classical remoting, inclusively. That is, WCF is not available, you would need v.3.5 or 4.0. For your task probably the most suitable approach is the one based on TcpListener/TcpClient.

You need not worry about the underlying working of TCP too much if you are using socket programming.

For an overview on the TCP protocol start here[^].
Afterwards, you can look at TCP/IP Chat Application Using C#[^] for an actual implementation of a chat program using TCP.
