What is network concepts?

Network concepts encompass the fundamental principles and technologies underlying how devices communicate with each other. This includes topics like network topologies (e.g., star, bus, mesh), protocols (e.g., TCP/IP, HTTP), addressing (e.g., IP addresses, MAC addresses), routing, switching, network security, and various network models like the OSI model. These concepts are crucial for understanding how data is transmitted, managed, and secured across networks, ranging from small home networks to large enterprise networks and the internet.
