The preset applications are among the most widely used
Internet applications. They include the following:
FTP (File Transfer Protocol) - A protocol used to transfer
files over a TCP/IP network (Internet, UNIX, etc.). For
example, after developing the HTML pages for a website
on a local machine, they are typically uploaded to the web
server using FTP.
Telnet - A terminal emulation protocol commonly used on
Internet and TCP/IP-based networks. It allows a user at a
terminal or computer to log onto a remote device and run
a program.
SMTP (Simple Mail Transfer Protocol) - The standard e-
mail protocol on the Internet. It is a TCP/IP protocol that
defines the message format and the message transfer
agent (MTA), which stores and forwards the mail.
DNS (Domain Name System) - The way that Internet
domain names are located and translated into IP addresses.
A domain name is a meaningful and easy-to-remember
“handle” for an Internet address.
