What's the difference between an intranet and an extranet? This video provides a quick overview of these two important types of internal computer networks.

An intranet is a private network that operates within an organization and is not accessible from the internet. Intranets are used to share information, applications and computing resources among employees. They allow for collaboration and access to systems like file shares, email servers and internal websites.

An extranet extends an organization's intranet by providing secure access to some of its systems and information to outside users. This can include partners, vendors, clients or customers. Extranets use many of the same protocols and security measures as an intranet but allow outsiders to log in through authentication.

Some key differences between the two:

Intranets are only accessible within an organization's internal network, while extranets grant access to selected external users.

Intranets connect internal users and resources, while extranets link an organization to specific users outside the company firewall for collaboration.

Security is typically tighter on intranets since only employees can access systems, while extranets require special protocols or VPNs for external users.

I hope this overview helps explain the purposes of intranets versus extranets. Let me know if you have any other questions!
