COMPTIA A+ Chapter 2
"Chapter 2" in CompTIA A+ study materials varies by textbook, but in the most widely used CompTIA A+ Complete Review Guide (Core 1 Exam 220-1101 and Core 2 Exam 220-1102), Chapter 2 is titled "Networking" and covers the entire Core 1 Networking domain (23% of the exam) . The chapter systematically addresses TCP/UDP ports and protocols (FTP, SSH, Telnet, SMTP, DNS, DHCP, HTTP, HTTPS, RDP, and others), wireless networking technologies including frequencies, channels, Bluetooth, 802.11 standards, NFC, and RFID, services provided by networked hosts such as web, mail, file, print, DNS, DHCP, and AAA servers along with IoT and SCADA systems, common network configuration concepts (DNS record types, DHCP, VLANs, VPNs), networking hardware devices (routers, switches, access points, firewalls, patch panels, PoE, cable/DSL modems, ONTs, NICs, and SDN), SOHO network installation and configuration with IP addressing, APIPA, subnet masks, and gateways, Internet connection types and network types, and networking tools including crimpers, cable strippers, Wi-Fi analyzers, toner probes, punchdown tools, cable testers, loopback plugs, and network taps . Each section concludes with "Exam Essentials" summarizing key points, followed by review questions to test retention. Note that in some other A+ textbooks, Chapter 2 may cover different topics such as "Expansion Cards, Storage Devices, and Power Supplies" or "Storage Devices, Power Supplies, and Adapters," so candidates should verify the table of contents of their specific study guide .
