Understanding Intranet, Extranet, and Network Classification. | Full Course Network

Computer networks help people and organizations share information and communicate efficiently. An Intranet is a private network used within an organization to securely share data, resources, and communication among employees. An Extranet extends limited access of the intranet to external users such as customers, suppliers, or business partners through secure authentication. Network classes are categories of IP addresses used in computer networking to identify devices and manage network sizes. The main classes are Class A, Class B, and Class C, each designed for different numbers of hosts and organizations. Understanding intranet, extranet, and network classes is important for building secure and efficient communication systems in modern networking environments.
