What network type is essentially a private Internet for an organization?

• A. Internet
• B. Intranet
• C. Extranet
• D. Local Area Network

Answer: (B)

An intranet is a private network within an organization that uses the same Internet technologies (like IP, TCP, and HTTP) but is restricted to authorized users. Because it sits behind firewalls and may require VPN access, it functions as a private Internet for internal use, giving employees access to internal websites, email, file shares, calendars, and business applications. The key idea is that it provides the broad capabilities of the Internet, but only for the organization’s members. Why not the others: The public Internet would be accessible publicly and isn’t restricted to one organization. A Local Area Network is typically confined to a single location and doesn’t inherently provide internal web-based resources or the same cross-location reach that an intranet can. An extranet extends some internal resources to selected external users (partners, suppliers, customers), so it isn’t private to just the organization's staff.
