Learn the fundamentals of computer networking through a comprehensive 13-part tutorial series that covers everything from basic digital signal transmission to complex network protocols. Start with the basics of sending digital information over wires and progress through fiber optics, RF encoding, and clock synchronization techniques including Manchester coding. Analyze real Ethernet encoding examples and understand the critical importance of data framing and various frame formats. Explore the lower layers of the OSI model before diving into the Internet Protocol (IP) and Address Resolution Protocol (ARP) for mapping between IP and Ethernet addresses. Examine actual ARP and ping packets to see these concepts in action, then master hop-by-hop routing principles. Conclude with an in-depth study of the Transmission Control Protocol (TCP), including a complete TCP connection walkthrough, and apply your knowledge to understand real-world network failures through a case study of Facebook's five-hour outage.
