Which protocol is used to move files and folders over a network or the Internet?

• A. HTTP
• B. FTP
• C. DNS
• D. ICMP

Answer: (B)

Moving files and folders over a network is handled by a protocol built specifically for file exchange. File Transfer Protocol (FTP) is designed for uploading, downloading, and managing files across machines, including directory structures and multiple files in one session. It operates over TCP and traditionally uses port 21 for control commands, with data transfers on port 20 in active mode (or on dynamically allocated ports in passive mode), which makes it well-suited for moving entire folders reliably. Other options have different primary roles: HTTP is mainly for retrieving web content, not optimized for general file management or folder transfers; DNS translates domain names to IP addresses rather than moving data; ICMP is used for network diagnostics and error reporting, not for transferring files.
