Network Fundamentals encompass the foundational concepts related to how devices connect and communicate with each other. This includes understanding network topologies (e.g., bus, star, mesh), network models (e.g., OSI model, TCP/IP model), IP addressing (IPv4 and IPv6), subnetting, routing protocols (e.g., RIP, OSPF, BGP), network hardware (e.g., routers, switches, hubs), and common network protocols (e.g., HTTP, DNS, SMTP, TCP, UDP). A strong grasp of network fundamentals is essential for anyone involved in network administration, software development, cybersecurity, or any field that relies on networked systems.
