Despite the long-standing presence of the internet in our lives, there remains a significant portion of the population unaware of how their data is transmitted, the speed of their connections, and the security of their online activities.It is essential to consolidate knowledge in this field, enabling not only everyday users to understand the mechanics of their online interactions for troubleshooting purposes but also to equip professionals with accurate insights into this realm.In pursuit of this goal, the author conducted experiments and conducted extensive online research.Through a comparative analysis of various protocols, two emerge as particularly valuable and widely employed: Secure Shell (SSH) and Hypertext Transfer Protocol (HTTP).SSH, renowned for providing remote shell access in Linux environments, exhibits exceptional scalability, making it suitable for file transmission and even for launching desktop software.For instance, applications like XShell facilitate running graphical software on Linux servers, akin to remote desktop functionality.HTTP, on the other hand, is a versatile protocol capable of web browsing, file downloads, media streaming, and serving as an effective management tool.Much like SSH, HTTP enables web server management through web-based dashboards, often referred to as "web backstages."Moreover, it facilitates file uploads and provides tools for establishing shell connections, allowing users to efficiently manage their websites through the command line interface.These protocols, SSH and HTTP, represent essential components of modern internet communication and management.
