Explain Anonymous FTP.

Use of a login password and name helps maintain file secure from unauthorized access. Though, sometimes these authorizations can also be inconvenient.  Especially, requiring each user to contain a valid name and password makes this difficult to permit arbitrary access. For illustration, assume a corporation finds a bug into one of the programs this sells. The corporation may create file of changes, and create the file available to anyone.

To permit arbitrary users to access a file without a specific login and password anonymous FTP is used, in which access to an FTP server is allowed using login name anonymous and password guest.
