A more dissected way:
An intranet is a private network that is only accessible by authorized users. The "intra" prefix means "internal" and therefore implies that the intranet is designed for internal communication. "Inter" (as in Internet) means "middle" or "in the middle". Since there is only one Internet, the word "Internet" is capitalized. Because many intranets exist around the world, the word "intranet" is written often.
Intranets can be limited to a specific LAN, or can be accessed remotely via the Internet via a tunnel (tunel). Internal intranets are generally the most secure because they can only be accessed from within the network. To access an intranet over a wide area network (WAN), you often need to enter your login information.
Intranets serve many different purposes, but the main goal is to make communication within organizations and businesses easier. For example, an enterprise can create an intranet that allows employees to share messages and files securely. It also helps system administrators send messages and update all machines connected to the intranet more quickly and simply.
Most intranet network solutions have web interfaces for users to access. This interface provides information and tools for employees and group members. It can include calendar, project time, task list, secret files and a messaging tool to communicate with other users. The intranet website is often called a portal and can be accessed with an intranet URL. If the intranet is restricted to an intranet, the user will not be able to access it from (or out) outside the intranet.
Examples of intranet intranet services include Microsoft SharePoint, Huddle, Igloo, and Jostle. While some services are open source and free, most intranet solutions require a monthly fee. The cost is usually related to the number of users on the intranet, the more users the greater the amount of money to spend and vice versa.
Good luck!
