📁 What's Inside

Network fundamentals Network Components, Types and Connections Wireless and Mobile Networks Build a Home Network Communication Principles Network Media The Access Layer Internet Protocol IPv4 and Network Segmentation IPv6 Addressing Formats and Rules Dynamic Addressing Formats and Rules Gateways to Other Networks The ARP Process Routing between Networks TCP and UDP Application Layer Services Network Testing Utilities

🧪 Labs Covered

Lab	Concepts Practiced
Basic LAN Setup	Switch config, end-device connectivity
IP Addressing	Subnetting, assigning static IPs
Router Config	Default gateway, inter-VLAN routing
DNS & DHCP	Automatic IP assignment, name resolution
Wireless Setup	SSID config, WPA2 security

🗝️ Key Concepts Learned

• OSI & TCP/IP models — how data travels across a network layer by layer
• IP addressing & subnetting — calculating network ranges and host limits
• Switches & routers — how packets are forwarded at Layer 2 and Layer 3
• DHCP & DNS — how devices get addresses and resolve names
• Basic network security — port security, disabling unused ports

🛠️ Tools Used

• Cisco Packet Tracer — network simulation
• Cisco IOS CLI — device configuration commands

💡 Sample IOS Commands
