If you do not understand that description, then you need to first do step 0: Learn to effectively develop software. This includes being good at at least two different programming languages, and being able to read and understand the manual pages and documentation of the system libraries.
If you do not yet have those skills, you cannot develop a robust game server. Right now, you're trying to learn calculus, from a textbook written in Latin, without knowing any Latin. You need to learn the Latin before you can learn the calculus.
If you want one-on-one help, there are many contractors and consultants that will spend their time helping you out. That will cost money, though.
Actually, i have successfully coded many many things in about 6 or 7 other languages. And learning to effectively code has nothing to do with it. I was asking what requirements i need. Suchas the include files. I have now coded a server btw. I was simply asking for the required information needed to be able to code a server. And actually, calculus is a good suggestion but is not actually necessary. Anyways. Thanks guys for all your help. I followed a WinSock tutorial to get started and coded the rest of the server myself. Hoping that i will have my MMORPG done by December. Good day everyone.
