1. Understanding TCP/IP Fundamentals

This tutorial provides a foundational understanding of the Transmission Control Protocol/Internet Protocol (TCP/IP) suite, the bedrock of modern internet communication. We'll cover:

• The layered architecture of the TCP/IP model.
• Key protocols like IP, TCP, UDP, and HTTP.
• How data packets travel across networks.

Key Takeaways: Network layers, packet switching, connection-oriented vs. connectionless communication.

// Example snippet illustrating IP addressing
            function getIpAddress() {
                // Placeholder for actual IP retrieval logic
                return "192.168.1.100";
            }
            console.log("Your current IP address is: " + getIpAddress());
            

2. Setting Up a Basic Home Network

Learn how to configure your home router, connect devices, and ensure a stable internet connection. This guide includes:

• Router setup and wireless configuration.
• Connecting wired and wireless devices.
• Basic troubleshooting steps.

Best Practices: Strong Wi-Fi passwords, default router credentials change.

3. Demystifying DNS: How Domain Names Work

Understand the Domain Name System (DNS) and how it translates human-readable domain names into IP addresses. Topics include:

• DNS hierarchy and record types (A, CNAME, MX).
• The DNS resolution process.
• Common DNS issues and how to diagnose them.

Did You Know? DNS queries are one of the most frequent network requests on the internet.
