There are two ways that you can log in to an FTP site, anonymously and normally.
Anonymous—When you log in anonymously, you do not use a specific user name or password. If you are connecting anonymously to a site, you need to leave User name and Password blank, and make sure you select the Anonymous option.
Normal—If you want to connect to an FTP site that your ISP (Internet Service Provider) or Web Hosting service set up for you, you will use a normal login. The ISP will provide you with the Host Address, User name, and Password. Use this information to take advantage of special permissions and privileges not available when you log in anonymously.
