The key difference is that the internet is a public, global network accessible to anyone, while an extranet is a private network that grants controlled access to authorized external users to parts of a company's intranet.
Here's a breakdown:
Understanding the Internet
The internet is a vast, globally connected network of computers that enables users to share information and resources.
- Accessibility: Open to the public; anyone with an internet connection can access it.
- Purpose: Global communication, information sharing, e-commerce, entertainment, and more.
- Security: Inherently less secure due to its public nature, requiring robust security measures to protect data.
Understanding the Extranet
An extranet is a private network that allows controlled access to authorized external users, such as suppliers, vendors, partners, or customers, to specific parts of a company's intranet. It acts as a bridge between a company and its external stakeholders.
- Accessibility: Restricted to authorized users with specific credentials.
- Purpose: Facilitating collaboration, streamlining supply chain management, providing customer support, and sharing specific information with partners.
- Security: Typically more secure than the internet, as access is controlled and monitored.
Internet vs. Extranet: A Comparative Table
| Feature | Internet | Extranet |
|---|---|---|
| Accessibility | Public; open to anyone | Private; restricted to authorized users |
| Purpose | Global communication and information access | Collaboration with external partners/customers |
| Security | Requires robust security measures | More secure due to controlled access |
| Ownership | No single owner; decentralized | Owned and managed by a specific organization |
| Example | World Wide Web, email | Supplier portal, customer support website |
Examples of Extranet Use
- Supplier portals: Allowing suppliers to access inventory levels, order information, and delivery schedules.
- Customer support websites: Providing customers with access to FAQs, troubleshooting guides, and support forums.
- Partner portals: Enabling partners to access sales materials, marketing resources, and training programs.
- Online banking for business clients: Business clients can manage their banking with controlled access via extranet.
In conclusion, the internet is a public highway for global communication, while an extranet is a private road connecting an organization to its key external partners, all with the goal of enhanced collaboration and streamlined business processes.
