INTERNET AND EXTRANET IN VIRTUAL PRIVATE NETWORK

ABSTRACT An extranet extends an intranet by providing various levels of accessibility to authorized members of the public. For example, a corporation may extend their intranet to provide access to specific information, such as their ordering system, to registered customers. The largest and most widely accessed network is the Internet, a worldwide network of computers that is not controlled by any one organization. An intranet is a network that is used by a single organization, such as a corporation or school, and is only accessible by authorized users. The purpose of an intranet is to share information. However, a firewall is also used to lock out unauthorized users. A firewall is a network security system that prevents unauthorized network access. This is the world-wide network of computers accessible to anyone who knows their Internet Protocol (IP) address - the IP address is a unique set of numbers (such as 209.33.27.100) that defines the computer's location. Most will have accessed a computer using a name such as http://www.hcidata.com. Before this named computer can be accessed, the name needs to be resolved (translated) into an IP address.
