Terms to Know • Internet Service Provider (ISP): company that connects customers with PCs and browsers to the Internet • Virtual hosting: a company with its own domain name, hosted by an ISP to conduct business via the Internet • Virtual domain: a company with its own domain name, hosted by an ISP to conduct business via the Internet • Domain name: a company’s identifier in cyberspace © 2007 Prentice-Hall, Inc

  4. Why Use an ISP? • Most client organizations are anxious to go on the Internet without questioning the reliability of the ISP that can accommodate their Web site • There is more to deciding on an ISP than price: • Technology • Staffing • Speed • Amount of congestion • Resources to host your own Web site: • Hardware - A Web server, communication gear, and a special router: $5,000 to $18,000 a year • Communications - Typically a T1 or fractional T1 line: $8,000 to $12,000 per year • Staff - At least a Webmaster, a Web designer, and a help desk: $45,000 to $80,000 per year • Total - $58,000 to $110,000 per year © 2007 Prentice-Hall, Inc

  5. The Infrastructure of an ISP Provider • Your company Web site has to be stored on a Web server that is always connected to the Internet by a high-speed link • An ISP should provide: • Standby electric power as backup to keep the site available in the event of a blackout. • Redundant fault-tolerant servers to ensure that your Web site will continue in the event of a hard drive or a server breaks down. • Redundant communications lines to keep your site active in the event a phone line or a router goes down • One or more firewalls to protect your Web site from hackers or unauthorized access. © 2007 Prentice-Hall, Inc
