TCP/IP is the foundational protocol suite that governs how data is addressed, transmitted, and received across networks, including the internet. For the CompTIA A+ Core 2 exam, candidates must understand core concepts such as IP addressing, subnet masks, default gateways, DNS, and DHCP, as well as how these settings are configured on Windows clients. A solid grasp of TCP/IP is required to diagnose and resolve the network connectivity issues that technicians encounter most often in the field.
