They can tailor it to their specific needs, customize the design, and restrict access to certain information based on user roles and permissions. In terms of functionality, the internet serves as a platform for communication, information sharing, and conducting online transactions. It enables people from different parts of the world to connect and exchange information. On the other hand, intranets serve as a central hub for communication and collaboration within an organization. It facilitates the efficient sharing of information between employees and departments, promoting productivity and streamlining processes. In conclusion, the internet and intranet are two distinct types of networks that serve different purposes. The internet is a global network accessible to the public, while an intranet is a private network limited to an organization. The internet is a tool for communication and information sharing, while an intranet is designed to enhance internal collaboration and productivity. As a university student, it is crucial to understand the differences between internet and intranet and their functionalities, as it can greatly impact the success of an organization's operations.
