It uses two ports - a command port to send and receive commands, and a data port to transfer files. The document outlines how FTP connections and transfers work, how to configure FTP servers on Windows, and common FTP client and server software. It also discusses requirements for FTP and provides steps for installing and configuring the FTP role and services in Windows Server 2008. Advantages of FTP include efficient bulk data transfer and automatic backups, while disadvantages include potential security issues and difficulty filtering active FTP connections.
