Network Fundamentals

Strong networks start with strong fundamentals — master the basics, and the possibilities are endless

Network Fundamentals
Network fundamentals cover the essential building blocks of computer networking. This includes understanding how devices such as routers, switches, firewalls, servers, and end-user systems connect to form Local Area Networks (LANs) and Wide Area Networks (WANs). Key topics include the OSI and TCP/IP models, IP addressing and subnetting, VLANs, wireless connectivity, and basic security concepts. Mastering these foundations provides the skills needed to design, troubleshoot, and secure modern networks.
