Welcome to Chapter 1 of my CCNA Course! I’m CyberEd, and in this video we’re breaking down the origins of networking, how the internet came to be, and the essential concepts every new network engineer must understand. This chapter covers: ✔ The evolution of networking and the internet ✔ ARPANET and packet switching ✔ TCP/IP and how it became the global standard ✔ Network sizes (SOHO, LAN, WAN) ✔ Core networking devices ✔ Internet governance (IETF, IANA, ICANN) If you’re studying for the CCNA 200-301, building a career in networking, or just trying to understand how the internet actually works, this is the perfect place to start.
