"description":"Three communication protocols that are, or have been, important for the internet:\n\nSSH: Secure Shell. A protocol that allows users to securely log in to a remote computer via a command-line interface, which is very useful for managing computers on a network.\n\nFTP: File Transfer Protocol. Largely obsolete these days due to its lack of security, but was once widely used for transferring files to and from webservers.\n\nHTTP: Hypertext Transport Protocol. The thing that makes the web work - when you visit websites, your browser communicates with the site via HTTP messages.",
