30 Comprehensive Network Fundamentals Mind Maps

The article compiles a set of thirty mind‑map images that systematically illustrate core concepts of computer networking. Each diagram focuses on a specific topic, allowing readers to visualize and connect the material.

TCP/IP Network Protocol Stack – an overview of the layered architecture and the functions of each layer.

TCP/IP Protocol Layering – a visual breakdown of the protocol hierarchy.

Transmission Media Introduction – key characteristics of different physical media.

Ethernet Frame Structure – the composition of Ethernet frames and their fields.

IP Addressing – fundamentals of IPv4 addressing, subnetting, and address allocation.

Transport Layer Protocols – the roles of TCP, UDP, and related mechanisms.

Routing Basics – concepts of routing, static routing, and routing tables.

Static Routing Fundamentals – configuration steps and use‑cases for static routes.

Distance‑Vector Routing – RIP – principles and operation of the Routing Information Protocol.

Link‑State Routing – OSPF – an outline of OSPF’s algorithm and area design.

HDLC & PPP Principles and Applications – framing methods for point‑to‑point links.

Frame Relay Principles and Configuration – virtual circuit concepts and setup.

PPPoE – encapsulation of PPP over Ethernet.

NAT (Network Address Translation) – translation techniques for IPv4 address conservation.

VLAN Principles and Configuration – logical segmentation of Ethernet networks.

VLAN Routing (Inter‑VLAN Routing) – routing traffic between VLANs.

GARP and GVRP – protocols for address and VLAN registration.

STP (Spanning Tree Protocol) and RSTP – loop‑prevention mechanisms in switched networks.

DHCPv6 – IPv6 address allocation process.

The author suggests bookmarking the collection and, after reviewing each mind map, redrawing the diagrams to reinforce memory and integrate the concepts into one’s own mental model.
