Introduction to DNC
File Transfer Protocol, commonly known as FTP, is a that facilitates the transfer of files between a client and a server over a network, typically the internet. It serves as a virtual bridge, enabling users to upload files from their local machines to remote servers or download files from servers to their devices. FTP was designed with the primary objective of simplifying the process of file sharing, distribution, and management, and it continues to be an integral part of many industries .
Historical Background and Evolution: The origins of FTP can be traced back to the early 1970s when the need for a standardized method of file transfer emerged.

How FTP Works
FTP functions on a client-server model, where the client initiates requests and the server responds accordingly. The client is typically a user’s computer or device equipped with FTP , while the server hosts the files to be accessed or transferred.
| FTP Commands | Description |
|---|---|
| USER | Authenticate the user with a username. |
| PASS | Authenticate the user with a password. |
| LIST | Retrieve a directory listing of files on the server. |
| RETR | Retrieve a specific file from the server. |
| STOR | Store a file on the server. |
| DELE | Delete a file on the server. |
| QUIT | End the FTP session and terminate the connection. |
Key Components of FTP
1. FTP Server: An FTP server is a dedicated computer or hosts files and directories accessible to authorized clients. It manages incoming requests from clients, authenticates users, and governs access rights to files and directories. The server responds to client commands and enables data transfers based on those commands.
2. FTP Client: An FTP client is software used by end-users to connect to FTP servers. Clients provide an interface for users to interact with remote servers, navigate directories, upload, download, and manage files. FTP client software is available for various platforms and often includes both graphical user interfaces (GUI) and command-line options.
| FTP Responses | Description |
|---|---|
| 220 | Server ready |
| 331 | User name okay, need password |
| 230 | User logged in, proceed |
| 150 | File status okay; about to open data connection |
| 226 | Closing data connection; request file action okay |
| 250 | Requested file action okay, completed |
| 530 | Not logged in |
| 550 | Requested action not taken; file not found |
