All over the world, Linux systems routinely deliver Web pages, news articles, music, and other services to millions of users.
The journey from a user's computer to the Linux service, requires an intricate mesh of network hardware and software.
This module examines the different aspects of Internet services and how they work. IP addresses and the Domain Name System allow users to establish connections to Linux systems.
Once there, port numbers and names give those users access to the services. Finally, standalone and transient network servers provide the actual service.

Overview of Internet Applications and Commands
When it comes to features and ease-of-use issues, applications that come with Redhat for accessing the Internet can rival those of any operating system.
For every major type of Internet client application, there are at least three or four graphical and command-line tools to choose from.
While Linux has offered high-quality servers for Web, mail, FTP, and other Internet services for years, current versions of these desktop Internet applications have become both solid and rich in content. If Web browsing and e-mail are your primary needs in a
desktop system, RHEL can give you a similar experience to that of your Windows operating system.
