What is the standard network protocol used for transferring files between computers?

The standard network protocol used for transferring files between computers is File Transfer Protocol (FTP). FTP is specifically designed to facilitate the transfer of files over a network, allowing users to upload or download files from one computer to another easily. It operates on a client-server model, where a client can connect to an FTP server to access shared files.

In contrast, HTTP (Hypertext Transfer Protocol) is primarily used for transferring web pages and data on the internet, while HTTPS (HTTP Secure) provides a secure version of HTTP by encrypting data transfers, typically for web browsing rather than file transfer. SMTP (Simple Mail Transfer Protocol) is used for sending emails, which does not directly relate to file transfer between computers. Therefore, FTP is the correct answer as it directly addresses the requirement for a protocol designed for file transfer.
