Answer 2

Ftp is a protocol. You can find some basic info here: http://en.wikipedia.org/wiki/File_Transfer_Protocol
or more detailed info here: http://tools.ietf.org/html/rfc959
In order to use ftp you just have to make a connection to a host on port 21. You can do it manually and use the commands that you can find in the documentation of the protocol at the link i gave you. This is interesting to try as it can lead you to a better knowledge. On the other side it can be more difficult and not very comfortable if you have to manage many files and folders, so you can use a software that can manage ftp. There are many programs that you can use, for a comparison you can see here: http://en.wikipedia.org/wiki/Comparison_of_FTP_client_software
I recommend you a free and open source software like Filezilla.
Of course you can use the ftp protocol as a client (for accessing files) or as a server (for sharing files).

File Transfer Protocol, better known as FTP, is a procedure used to upload and download files to and from your web server. FTP is a special way to login to another Internet site for the purposes of retrieving and/or sending files.
In order to use FTP, you'll need to download and install a software program on your computer. The most widely used FTP program is Smart FTP. You can find it here: http://www.smartftp.com. Also check out other FTP Downloads here.
When you first launch the FTP program, a startup screen will appear. This screen will enable you to add your website information and allow the program to connect with your server. You simply fill in the information where indicated with the following information:
Profile Name - This name will be added to the selection list of profile names. Select your profile name according to your domain. For example, if your domain name were smiths.com, your profile name might be Smiths.
Host Name/Address - Your domain name address.
Example - www.candidinfo.com
Host Type - The type of server in which your website is hosted. The standard is Unix.But you can probably skip it.
User ID - Your hosting User ID. Example - candidinfo.
Password - Your hosting password.
Depending on which FTP client you use, the names may be slightly different.
Once the FTP program has connected with your server,you will see the files on your computer in the left window and the files on your server will be displayed in the right window.

Answer 4

Don't use FTP unless you must. It is utterly insecure.
