Virtual Worlds software platforms are typically comprised of software installed on the end-user’s computer (client) and software running on an Internet server which manages communications, objects, spaces, avatars, and community elements. Client software is either a stand-alone program or a web browser plug-in and can be downloaded from a web site or installed directly from a CD-ROM / DVD-ROM. Platforms may also support third-party programs to enable certain features or extensions such as audio / video playback.
