The first step in learning to do network programming is to realise that 
communication over a network is a two-way process, involving a sender of 
information and a receiver of information. Unless the receiver can 
understand what the sender sends, there is little or no point in sending 
the information.

It is therefore wise to at least attempt to stick to a core protocol which 
is understood by both the sender and the receiver. For example, there is a 
protocol for the spelling of "please" - it goes like this: first a 'p', 
then an 'l', then an 'e', then an 'a', then an 's', and finally another 
'e'. Some receivers understand "plz" to be an abbreviation for "please", 
but by no means all - and those who do understand it have to do extra 
processing to facilitate the translation. Senders should not lay such 
unnecessary burdens on their receivers.

It is far better for the sender to stick to well-established protocols than 
to take arbitrary shortcuts and hope that the receiver will be able to work 
out what you meant.

The book you want should be available from your local bookstore. It is 
called "Unix Network Programming", Volume 1. Volume 2 covers other stuff 
which you don't need to know just yet. Even if you are using Windows, it is 
well worth buying this book, since almost all the core knowledge in it is 
transferable to Windows.
