Real-Time Communication

Text, audio and video communication can occur in real time on the Web. This capability allows people to conference and collaborate in real time.

Chat programs allow multiple users to type to each other in real time. Internet Relay Chat and America Online's Instant Messenger are prime examples of this type of programs.

More enhanced real-time communication offers an audio and / or video component. CU-See Me is one of the most popular software programs of this type. Even more elaborate are programs that allow for true real-time collaboration. Featured collaboration tools include:

· audio: conduct a telephone conversation on the Web;

· video: view your audience;

· file transfer: send files back and forth among participants;

· chat: type in real time;

· whiteboard: draw, mark up, and save images;

· document / application sharing: view and use a program on;

· another's desktop machine;

· collaborative Web browsing: visit Web pages together.

Push: Push refers to a technology that sends data to a program without the program's request. This is the opposite of the typical «pull» of the Web, in which the user clicks on a link to request a file from a server. With push, the data is sent automatically. Content is sent through a «channel». The early Web-based implementation of push was commercial. Push can also be used to deliver software upgrades to a desktop machine.
