IP addressing is one of the most fundamental concepts in networking. Every network engineer and senior system administrator should understand how IPv4 and IPv6 addresses identify network interfaces, how hosts determine whether a destination is local or remote, and how subnet masks and prefixes define network boundaries. This article establishes the IP addressing foundation that … Read more
In Part 1, we established the basic networking concepts and devices. In Part 2, we examined how traffic moves between hosts, including ARP, default gateways, switches, routers, encapsulation and packet flow. This part focuses on the technology that actually carries Ethernet traffic across a LAN. You will learn: Ethernet fundamentals Copper and fiber media Ethernet … Read more
In Part 1, we covered the basic building blocks of networking, including network devices, OSI and TCP/IP models, MAC addresses, IP addresses, frames, packets, bandwidth, latency and basic network terminology. In this part, we will focus on a much more important practical question: What actually happens when one computer communicates with another computer? Understanding this … Read more
Networking is one of the most important areas for System Administrators, Network Administrators, System Engineers, Network Engineers and IT Infrastructure professionals. Before moving into CCNA, CCNP and CCIE-level networking, it is important to understand how computers communicate, how network devices operate, how data moves through a network, and how the OSI and TCP/IP models describe … Read more
