HOW TO TRANSFER A FILE

File Transfer Protocol
Transfer Protocol service (known as FTP in short) enables an Internet user to move a file from one computer another on the Internet. A file may contain any type of digital information - text document, image, artwork, sound, software, etc. Moving a file from a remote computer to ones own computer is known as downloading  the file, and moving a file from ones own computer to a remote computer is known as uploading the
Using FTP service, a file transfer takes place in following manner

1.A user executes the ftp Command on his/her local computer* specifying address of the remote
computer as a parameter
2.An FTP process running on user's computer (called FTP client process) establishes a connection with an FTP process running on remote computer (called FTP server process).
3.The system then asks the user to enter his/her login name and password on the remote computer to
ensure that the user is authorized to access the remote computer.
4.After successful login, desired file(s) are downloaded or uploaded by using get (for downloading) and put (for uploading) commands. User can also list directories, or move between directories of the remote computer, before deciding which file(s) to transfer

Notice that a user needs access rights for a remote computer to transfer files to/from it; With this almost impossible to provide access rights to the vast number of users on the Internet to a computer that' sharable information. The concept of anonymous FtP site is used to overcome this problem. An anon) site is a computer allowing a user to log in with a username of anonymous and a password that is user’s address. The user can then download files that have been stored on it for sharing. Such sites are called publicly accessible sites because any user on the Internet can access them..

Of  course. FTP service is also used for more secure file transfer operations'. In such cases, a user needs username and  password to access a particular computer. This is common; for example, for organizations to let only certain people access their computer
