    Today companies have branches around the world. More than 11% of the US employers and employees work online either full-time or part-time, and that number is continuing growing. It is believed that it is a waste of time and money to fly around the world for face-to-face meetings. An effective solution to this problem is to use Web meetings.

A large group of presentations, training classes and meetings are done online without losing the face-to-face experience. Web meetings are online meetings where an organizer invites attendees to listen to or watch an online presentation by presenters. Besides, Web meetings can be recorded for later use in presentations or training projects or downloaded for on-demand playback. Presenters can take real-time surveys to study how to hold a successful meeting. Some Web meeting software programs can monitor the users' desktop behavior to see if they become distracted from the presentation and begin working on other documents. If so, the program can tell presenters when the listeners lose their attention, and how long the distraction lasts. In this way the presenters will know which parts of their meetings need improving.

Web meetings can work well because they're hosted on a server. Images from the presenter's desktop are taken, uploaded to a server and then downloaded by people who have access to the server Web meetings require a powerful server to deal with several images a second and “serve” them back to thousands of users at the same time.

Companies have two choices when it comes to these servers. They can either buy a special Web meeting server to host their meetings on-site, or they can pay for a Web meeting service every time and let the off-site provider worry about hosting the meetings. The choice depends on frequently the company holds
