Networking Fundamentals & TCP/IP

About this course

This course covers the foundational networking concepts and TCP/IP protocols required for the CompTIA A+ Core 2 exam, including how data moves across networks and how operating systems connect to and communicate over those networks. Learners benefit from understanding Ethernet, MAC addressing, IP addressing, subnetting, and the suite of TCP/IP protocols that underpin modern networking — plus the practical OS-level tools used to configure connections and troubleshoot network problems. Hands-on online labs provide experience with real network configuration and diagnostic tasks.

What you will learn

• How networking hardware and protocols work together, including Ethernet frames, MAC addresses, and the TCP/IP protocol suite.
• How to configure IP addresses, understand subnetting, and work with core protocols including DNS, DHCP, and HTTP.
• How to use OS-level networking tools to configure connections, test connectivity, and troubleshoot common network issues.
