Services of the internet

Internets support thousands of different kinds of operational and experimental services. A few of the most popular include the following:
E-mail (electronic mail) allows a message to be sent from one person to another, or to many others, via computer. Internet has its own e-mail standards that have also become the means of interconnecting most of the world's e-mail systems. Internet e-mail addresses usually have a form such as “editor@encarta.microsoft.com”, where “editor” is the e-mail account name, and “encarta.microsoft.com” is the domain identity of the computer hosting the account. E-mail can also be used to create collaborative groups through the use of special e-mail accounts called “reflectors” or “exploders” that automatically redistribute mail sent to the address.
The World Wide Web allows the seamless creation and use of elegant point-and-click hypermedia presentations, linked across the Internet in a way that creates a vast open knowledge repository, through which users can easily browse.
Gopher is a system that allows the creation and use of directories of files held on computers on the Internet, and builds links across the Internet in a manner that allows users to browse through the files.
FTP (File Transfer Protocol) is a set of conventions allowing easy transfer of files between host computers. This remains the biggest use of the Internet, especially for software distribution, and many public distribution sites now exist.
Usenet allows automatic global distribution of news messages among thousands of user groups, called newsgroups.
Telnet is the system that allows a user to “log in” to a remote computer, and make use of it.
