💻 Essential Windows Network Commands Every Network Engineer Should Know! 🌐

When troubleshooting a Windows network, the Command Prompt can be one of your most useful tools. Here are 9 commands worth keeping in your networking toolkit:

🔹 ipconfig — View IP address, subnet mask, gateway, and DNS information
🔹 netstat — Check active connections, listening ports, and network statistics
🔹 ping — Test connectivity and measure response time/packet loss
🔹 arp — View IP-to-MAC address mappings
🔹 tracert — Trace the path packets take to a destination
🔹 netsh — Configure and troubleshoot Windows network settings
🔹 nslookup — Query DNS records and troubleshoot name resolution
🔹 route — View and manage the Windows routing table
🔹 telnet — Test connectivity to a specific TCP port when the Telnet client is available

🧠 Pro Tip: Don’t just memorize commands—understand what the output tells you. A good troubleshooting workflow often moves from IP configuration → connectivity → DNS → routing → ports/services.

📌 Save this cheat sheet! It can be extremely useful for CCNA preparation, IT support, network troubleshooting, and real-world administration.

⚡ UDP vs TCP – What's the Difference?

Both UDP and TCP are transport layer protocols, but they serve different purposes. UDP prioritizes speed with minimal overhead, making it ideal for real-time applications, while TCP focuses on reliable, ordered, and error-checked delivery for critical data transmission.

🔹 UDP
✅ Connectionless and lightweight
✅ Faster with lower latency
✅ No acknowledgments or retransmissions
✅ Best for VoIP, video streaming, online gaming, and DNS

🔹 TCP
✅ Connection-oriented with a three-way handshake
✅ Reliable and ordered data delivery
✅ Error checking, flow control, and congestion control
✅ Best for web browsing, email, file transfers, banking, and business applications

💡 Rule of Thumb:
Choose UDP when speed matters. Choose TCP when reliability matters.
