There are several types of chat room variations online today. They include Java, Flash, Mirc, and shout boxes.
Java Chat rooms
By far the most common and popular chat script is based on java. Java is freely available and comes with virtually every computer sold today. To use a Java chat room you must have Java enabled in your browser (some people have Java turned off for security reasons). To turn on Java you will need to find the settings feature in your particular browser eg. Internet Explorer or Firefox.
Java chat rooms load quickly and are reasonably fast to use, some lag maybe noted in very busy chat rooms, if you are using an older computer, and if your Java version is out of date. Java and newly released Java updates for your computer can be downloaded for free from Java.com
What are Flash Chat rooms
Flash chat is an upgraded version of chat rooms that is becoming more and more popular. Flash chat rooms are powered by the Adobe/Macromedia Flash Player client which has been integrated into a website. By using high quality flash all around smoother design and performance can be obtained. Flash Chat rooms require that the Macromedia Flash Player from Adobe be installed on your computer. You can get the flash player (and player updates) for free from Adobe.com for your computer if it is not already installed.
IRC Chat rooms
IRC or Internet Relay Chat is a true multi-user chat network where people around the globe can meet and talk in channels or in private. Using an IRC client on your computer, you connect to an IRC server, which is in turn connected to one of several IRC networks. Networks have anywhere from tens to tens of thousands of people you can chat with. IRC was one of the very first chat systems on the world wide web. For more information see our article about IRC chat.
MIRC is a small computer program that allows you to use the internet relay chat system (IRC), you can simply download the software to your computer and use the software to connect to various servers around the world, to access their chat channels.
