What is FTP?

File Transfer Protocol

Quick Answer

A file transfer protocol (FTP) is a standard network protocol used to transfer files from one host to another over a TCP-based network. It allows users to upload and download files easily between computers or servers.

Overview

File Transfer Protocol, or FTP, is a method used to send and receive files over the internet. It works by establishing a connection between a client and a server, allowing users to transfer files back and forth. This process typically involves entering a username and password to gain access to the server where the files are stored. When a user wants to upload a file, the FTP client sends the file to the server, and when downloading, the server sends the file back to the client. This system is essential for web developers who need to manage files on their websites, as it allows them to update content, images, and other resources quickly. For example, a photographer might use FTP to upload large image files to their website without hassle. FTP is significant because it simplifies file management and sharing across networks. It is widely adopted in various industries for transferring large files securely and efficiently. Understanding how FTP works is crucial for anyone involved in networking or web development.
