If you have been exploring the Web for any length of time, then you have run across any number of Webcams in your travels. Webcams range from the silly to the serious -- a Webcam might point at a coffee pot or a space shuttle launch pad. There are business cams, personal cams, private cams, traffic cams... You name it and there's probably a Webcam pointed at it.
An enterprise network can be thought of as a plug-and-play platform for connecting many different computing devices. In this platform scenario, no user or group is an island. All systems can potentially communicate with all other systems while maintaining reasonable performance, security, and reliability.
The term network refers to any interconnected group or system designed specifically for sharing information among them. The basic goal of network infrastructure was to provide connectivity and it acted as a bridge between a communications medium and the applications that are built upon this medium. Most of the IT industry is based on network infrastructure without which almost all communications in the world would come to an end. The network infrastructure allowed the rapid development of many computer technologies related to connectivity and created a marketplace for new concepts. It is based on the standard reference model of the industry such as the four-layer Internet Protocol Suite model.
