Programming is done into two types. But most of the people confused with this.
What is server side and client side programming?
here i am clearing this doubts.
Server side scripting can hold events after post back of the page and client side scripting is to authenticate the page ahead of post back.

Here's a short summary i got from Wikipedia :

Client-side scripting generally refers to the class of computer programs on the web that are executed client-side, by the user's web browser, instead of server-side (on the web server). This type of computer programming is an important part of the Dynamic HTML (DHTML) concept, enabling web pages to be scripted; that is, to have different and changing content depending on user input, environmental conditions (such as the time of day), or other variables.
Web authors write client-side scripts in languages such as JavaScript (Client-side JavaScript) and VBScript.

Server-side scripting is a web server technology in which a user's request is fulfilled by running a script directly on the web server to generate dynamic web pages. It is usually used to provide interactive web sites that interface to databases or other data stores. This is different from client-side scripting where scripts are run by the viewing web browser, usually in JavaScript. The primary advantage to server-side scripting is the ability to highly customize the response based on the user's requirements, access rights, or queries into data stores.
When the server serves data in a commonly used manner, for example according to the HTTP or FTP protocols, users may have their choice of a number of client programs (most modern web browsers can request and receive data using both of those protocols). In the case of more specialized applications, programmers may write their own server, client, and communications protocol, that can only be used with one another.
Programs that run on a user's local computer without ever sending or receiving data over a network are not considered clients, and so the operations of such programs would not be considered client-side operations.

MMO's games mean which type of games?

MMORPG = Massive Multiplayer Online Role Playing Game ( examples: Eve Online , Lineage 2 , World of Warcraft, AION etc )

The principal of these games are simple. Supply your players by giving them a client which is used to connect to a server in order to interact with other people.
In other words the server keeps all the data, statistics , formulas of the game while the client keep the visual effect, game interface etc
