IT networking fundamentals cover the core concepts of how computers and devices communicate, including IP addressing, subnetting, routers, switches, protocols (TCP/IP, DNS, DHCP), and network topologies. This knowledge is essential for network administrators, help desk technicians, and anyone pursuing certifications like CompTIA Network+ or Cisco's CCNA. Understanding these basics is a prerequisite for troubleshooting connectivity issues and designing secure, efficient networks.
