Summary
1. The Internet is a global communications network that is used to transmit the information published on the World Wide Web (WWW) in a standard format based on Hypertext Markup Language (HTML) using different standard protocols such as HTTP and TCP/IP
2. Companies deliver e-business services to employees and partners through web servers which are often hosted at third-party companies known as ‘Internet service providers’ (ISPs). Web servers will be linked to applications servers, database servers and legacy applications to deliver these services
![Page 55: Chapter 3 E-business Infrastructure](https://reader033.fdocuments.net/reader033/viewer/2022061406/56813739550346895d9ec961/html5/thumbnails/55.jpg)

Summary
3. Consumers and business users access these e-business services using web browser software, with connections to the Internet also managed by an ISP through which they can access web servers
4. Intranets are private networks used inside companies to share information. Internet-based tools such as e-mail, FTP, and the World Wide Web are all used as methods of sharing this information. Not all Internet users can access intranets since access is restricted by firewalls and password controls. Extranets are similar to intranets, but they are extended beyond the company to third parties such as suppliers, distributors or selected customers
