What This Document Is
This is a detailed exploration of the File Transfer Protocol (FTP), a foundational method for transferring files across a network. Created for students in an introductory communication networks course at the University of California, Berkeley, this material delves into the mechanics and historical context of FTP, examining its role in the evolution of data communication. It provides a comprehensive look at how file transfers were traditionally handled before the widespread adoption of modern web-based methods.
Why This Document Matters
This resource is ideal for students seeking a deeper understanding of network protocols and their underlying principles. It’s particularly valuable for those studying communication networks, computer science, or related fields. Understanding FTP provides a crucial stepping stone to grasping more complex protocols and network architectures. It’s beneficial to review this material when learning about client-server models, data communication methods, and the historical development of the internet.
