File Transfer Protocol (FTP)
File Transfer Protocol (FTP) is a standard network protocol used for transferring files between a client and a server over the Internet or a local network. Introduced in the 1970s, FTP remains a widely used method for file sharing and transfer despite the emergence of newer protocols.
Key Features of FTP:
Two Modes of Operation:
Active Mode: The client opens a port and waits for the server to establish a connection.
Passive Mode: The server opens a port and waits for the client to establish a connection, which is more firewall-friendly.
Authentication Options: Supports both anonymous access and secure username/password authentication.
Transfer Capabilities: Handles large files and supports resuming interrupted transfers.
Common Use Cases:
Uploading and downloading website files to and from hosting servers.
Sharing large files within organizations.
Backups and data synchronization.
Security Considerations:
Traditional FTP transmits data, including passwords, in plain text, making it vulnerable to interception. Secure alternatives like FTPS (FTP Secure) and SFTP (SSH File Transfer Protocol) provide encryption to enhance data security.
Advantages:
Simplicity and ease of use.
Widespread support across platforms and software.
Despite its limitations, FTP continues to be a reliable tool for file transfer needs, particularly when combined with secure enhancements.
How CodeBranch applies File Transfer Protocol (FTP) in real projects
The definition above gives you the concept — but knowing what File Transfer Protocol (FTP) means is different from knowing when and how to apply it in a production system. At CodeBranch, we have spent 20+ years building custom software across healthcare, fintech, supply chain, proptech, audio, connected devices, and more. Every entry in this glossary reflects how our engineering, architecture, and QA teams actually use these concepts on client projects today.
Our work combines AI-powered agentic development, the Spec-Driven Development (SDD) framework, CI/CD pipelines with agent rules, and production-grade quality gates. Whether you are evaluating a technology for your product, trying to understand a vendor proposal, or simply learning, this glossary is written to give you practical, accurate context — not theoretical abstractions.
