What
is FTP?
FTP (File Transfer Protocol) is the simplest and most secure
way to exchange files over the Internet. Whether you know it or
not, you most likely use FTP all the time.
The most common use for FTP is to download
files from the Internet. Because of this, FTP is the backbone of
the MP3
music craze, and vital to most online auction and game enthusiasts.
In addition, the ability to transfer files back-and-forth makes FTP
essential for anyone creating a Web page, amateurs and professionals
alike.
When downloading a file from the
Internet you're actually transferring the file to your computer
from another computer over the Internet. This is why the T
(transfer) is in FTP. You may not know where the computer is that the
file is coming from but you most likely know it's URL
or Internet address.
An FTP address looks a lot like an HTTP,
or Website, address except it uses the prefix ftp:// instead of http://.
Most often, a computer with an FTP
address is dedicated to receive an FTP connection. Just as a
computer that is setup to host Web pages is referred to as a Web
server or Website, a computer dedicated to receiving an FTP
connection is referred to as an FTP server or FTP site.
What is an FTP Site?
An FTP site is like a large
filing cabinet. With a traditional filing cabinet, the person who
does the filing has the option to label and organize the files how ever
they see fit. They also decide which files to keep locked and
which remain public. It is the same with an FTP site.
The virtual 'key' to get into an FTP site
is the UserID and Password. If
the creator of the FTP site is willing to give everyone access to the
files, the UserID is 'anonymous' and the Password is your
e-mail address (e.g. name@domain.com). If the FTP site is not public,
there will be a unique UserID and Password for each person
who is granted access.
When connecting to an FTP site that
allows anonymous logins, you're frequently not prompted for a
name and password. Hence, when downloading from the
Internet, you most likely are using an anonymous FTP login and you don't
even know it.
To make an FTP connection you can use a
standard Web browser (Internet Explorer, Netscape, etc.) or a dedicated
FTP software program, referred to as an FTP 'Client'.
When using a Web browser for an FTP
connection, FTP uploads are difficult, or sometimes impossible, and
downloads are not protected (not recommended for uploading or
downloading large files).
When connecting with an FTP Client,
uploads and downloads couldn't be easier, and you have added security
and additional features. For one, you're able to to resume
a download that did not successfully finish, which is a very nice
feature for people using dial-up connections who frequently loose their
Internet connection.
What is an FTP Client?
An FTP Client is software that is designed to transfer files
back-and-forth between two computers over the Internet. It needs
to be installed on your computer and can only be used with a live
connection to the Internet.
The classic FTP Client look is a two-pane
design. The pane on the left displays the files on your computer
and the pane on the right displays the files on the remote
computer.

File transfers are as easy as
dragging-and-dropping files from one pane to the other or by
highlighting a file and clicking one of the direction arrows located
between the panes.
Additional features of the FTP Client
include: multiple file transfer; the auto re-get or resuming feature; a
queuing utility; the scheduling feature; an FTP find utility; a
synchronize utility; and for the advanced user, a scripting utility.
All of these features will be explained
in later tutorials. First you need to download and install an FTP
Client.
