Which of the following is most often used to transfer files between a computer and a server for the purpose of publishing a website?

The most commonly used method to transfer files between a computer and a server for the purpose of publishing a website is File Transfer Protocol (FTP). FTP is specifically designed for transferring files, allowing users to upload and download files to or from a web server. When building or updating a website, developers use FTP to manage the files that are hosted on the server, ensuring all necessary components such as images, styles, and scripts are correctly transferred and organized.

By contrast, Hypertext Transfer Protocol (HTTP) is primarily used for transferring web pages and related content that browsers request, rather than for direct file transfer. Simple Mail Transfer Protocol (SMTP) is utilized for sending emails, not for file transfer, which makes it irrelevant in this context. The term File Access Protocol (FAP) isn’t a standard or well-known protocol in web development or file transfer practices. Therefore, FTP stands out as the appropriate choice for this specific file transfer purpose.
