- 2. Basics of INTERNET and INTRANET The Internet and Intranet are two types of computer networks with different scopes and purposes. The Internet: is a global network of computers and devices that communicate with each other using standardized protocols, such asTCP/IP. It connects millions of users around the world, allowing them to share information, communicate, and access various services and resources. The Internet is a public network, which means that anyone with an Internet connection can access it. Examples of Internet services include email, file sharing, social media, and online shopping. An Intranet: on the other hand, is a private network that is restricted to a specific organization, such as a company, school, or government agency. It uses the same protocols as the Internet, but it is accessible only to authorized users within the organization. Intranets are often used to share information, documents, and resources among employees, departments, and teams. They can also be used for internal communication, collaboration, and project management. Intranets are typically secured by firewalls and other security measures to protect sensitive information from external threats. In summary, the Internet is a global network of public computers and devices, while an intranet is a private network that is restricted to a specific organization.
