This is a basic PPT about File Transfer Protocols. This explains why FTPs are importat and their basic functionality .

1. File Transferring
Protocols

2. File Transfer Protocol (FTP) is a protocol used to transfer
files over the Internet.
People commonly use FTP to make files available for
others to download, but you can also use FTP to upload
WebPages for building a website or for putting digital
photos on a picture sharing site.

4. The File Transfer Protocol (FTP) is a standard network protocol used
to transfer computer files between a client and server on a
computer network.
FTP is built on a client-server model architecture and uses separate
control and data connections between the client and the server.

7. • FTP uses a TCP (TCP is one of the main protocols in TCP/IP
networks) control and data connection.
• The TCP ( transmission control protocol) control connection
is used for opening / closing an FTP session and for transferring
commands from client to server.
• The data connection is used for transferring individual files between
client and server.
• Every file transfer uses a separate data connection.

8. Features
Interactive Access
FTP provides an interactive interface to allow humans to
interact with remote servers.
Format Specification
FTP allows the client to specify the type and
representation of stored data.
The user can specify whether a file contains text or binary data.
Authentication Control
FTP requires clients to authorize themselves by sending
a login name and password to the server before
requesting file transfers.
The server refuses access to clients that cannot provide a valid
login and password.

9. So how does FTP Works?
After a TCP connection is established, an FTP control
connection is created.
Internal FTP commands are passed over this logical connection based on
formatting rules established by the Telnet protocol. Each command sent
by the client receives a reply from the server to indicate whether
it succeeded or failed.
A data connection is established for each individual data transfer to be
performed.
FTP supports either normal or passive data connections, allowing either
the server or client to initiate the data connection.

13. The Goal of FTP
FTP was created with the overall goal of allowing indirect
use of computers on a network, by making it easy for users
to move files from one place to another. Like most TCP/IP
protocols, it is based on a client/server model, with an FTP
client on a user machine creating a connection to an FTP
server to send and retrieve files to and from the server. The
main objectives of FTP were to make file transfer simple,
and to shield the user from implementation details of how
the files are actually moved from one place to another. To
this end, FTP is designed to automatically deal with many of
the issues that can potentially arise due to format
differences in files stored on differing systems.

15. How To Start It?
To start FTP in Internet Explorer, type the FTP address into the Address
bar or click an FTP link on a webpage. If you click a link, you will be asked
whether you want to save the file or open it. (If you use a different web
browser, follow the instructions that came with your browser.)
FTP addresses start with "ftp://" rather than "http://." For example, to go to the
Microsoft FTP website, type ftp://ftp.microsoft.com, and then press ENTER.

17. How do I access FTP websites and
download files?
In your web browser's address bar, type the Internet address (URL) for the FTP site
you want to connect to (for example, ftp://ftp.microsoft.com/), and then press
ENTER.
The FTP site opens, and you can do one or more of the following:
To open a file or folder, click it.
To download a file or folder, right-click it, and then, in Internet Explorer,
click Save Target As. If you use a different web browser, follow the
instructions that came with your browser.
If you have permissions from the person who owns the FTP site, you can also open the
site in a Windows Explorer window. To open the site in this way, in Internet
Explorer, click the Page button, and then click Open FTP site in Windows
Explorer. In the new window, to download a file or folder, right-click it, and then
click Copy to Folder.06/26/16

18. How do I upload files to an FTP
website?
To upload files to an FTP website, you usually need certain permissions from the
person who owns the site. That person must also give you a user name and
password, which you'll need to sign in to the FTP site.
Open the FTP website in your browser.
Click Page, and then click Open FTP site in Windows Explorer. If you use a
different web browser, follow the instructions that came with your browser. If you
are prompted for an administrator password or confirmation, type the password
or provide confirmation.
In Windows Explorer, press ALT, click File, and then click Login as.
Type the user name and password, and then click Log On.

19. Can I use FTP to copy or move files
between websites?
Yes, but not directly between sites. You must first use FTP to download the
files to your computer, and then use FTP again to upload them to the
other website.
