Internet Protocols
Common
Internet protocols that enable you to access the Internet are
Hypertext Transfer Protocol (HTTP), HTTP Secure (HTTPS), File
Transfer Protocol (FTP), Simple Mail Transfer Protocol (SMTP), and
Network News Transfer Protocol (NNTP). In addition, Hypertext Markup
Language (HTML) and Dynamic HTML (DHTML) specify the formats of
pages displayed on the Web.
HTTP
is a convention for sending messages from a server to a client by
using TCP/IP. HTTP communications are in plain text and not
encrypted.
HTTPS enables you to make a secure Web server connection by using
Secure Sockets Layer (SSL). SSL is an encryption technology that
enables a secure connection between a server and a client. The URLs
for Web pages that require an SSL connection start with https://.
FTP
enables you to transfer files between two computers on a network.
SMTP
enables you to send e-mail over the Internet.
NNTP
enables you to post, distribute, and retrieve messages on Internet
and intranet newsgroups.
HTML
is the standard language for creating and formatting Web pages. HTML
defines how text appears when viewed in a Web browser.
DHTML refers to HTML extensions that support animations and enable
you to create interactive Web pages.
