Write short note on FTP.

File Transfer Protocol is a standard for the exchange of files across internet. Files of any type can be transferred, whether the file is an ASCII or binary file. They can be transferred to any system on the Internet provided that permissions are set accordingly.

The main objectives of FTP are as follows:

1. to promote sharing of files (computer programs and/or data)
2. to encourage indirect or implicit (via programs) use of remote computers
3. to shield a user from variations in file storage systems among hosts
4. to transfer data reliably and efficiently.
