READ CAPTION...👇 🚀 What is TRACERT? | Networking Basics Explained Have you ever wondered how your data travels from your computer to a website? That’s where TRACERT comes in. 🔎 TRACERT (Trace Route) is a network diagnostic command used in Windows to track the path that data packets take from your system to a destination server. 💡 What does it show? ✅ Each router (hop) in the path ✅ IP address of every hop ✅ Response time (in milliseconds) ✅ Where the delay or issue is occurring 💻 Command: tracert google.com or tracert 8.8.8.8 🧠 How does it work? TRACERT uses the TTL (Time To Live) concept: TTL = 1 → First router replies TTL = 2 → Second router replies This continues until the destination is reached If you see * * * in the output, it may indicate: Firewall blocking Router not responding Network issue 📌 TRACERT is very useful for: Network troubleshooting Identifying latency issues Interview preparation (especially for NOC / Network Engineer roles) Networking fundamentals build strong troubleshooting skills. Keep learning. Keep growing. 💪 #Networking #NetworkEngineer #NOC #CCNA #ABHI-CODE-KR

🌐 Routing vs Switching – The difference between Routing and Switching is absolutely essential. 🔶 What is Routing? Routing moves data between different networks. ✔ Operates at Layer 3 (Network Layer) ✔ Uses IP addresses ✔ Chooses the best path using routing tables ✔ Handles inter-network traffic 👉 Think of it as traffic control between cities. 🔷 What is Switching? Switching connects devices within the same network (LAN). ✔ Operates at Layer 2 (Data Link Layer) ✔ Uses MAC addresses ✔ Forwards frames inside the local network ✔ Handles intra-network traffic 👉 Think of it as traffic management within a building. 💡 Key Differences at a Glance Routing: • Layer 3 • IP-based decisions • Best path selection • Connects multiple networks Switching: • Layer 2 • MAC-based forwarding • Fast local communication • Connects devices inside LAN 🔥 Pro Tip: Routers maintain Routing Tables Switches maintain MAC Address Tables Both are equally important — one connects the world 🌍, the other keeps your local network running smoothly.

Network time protocol provides pretty much what its name says time. provide correct time to all network devices. in other words, NTP synchronizes the clock of the computer system over packet switch, variable-latency data networks. Correct network time within the network is important. Correct time allows the tracking of the event in the network in the correct order. Cock synchronize is critical for the correct interpretation of events within the Syslog data. Advantages of NTP : It provides internet synchronization between the computer devices. NTP provides enhanced security within the premises. NTP is used in authentication systems. NTP provides network acceleration which helps in troubleshooting problems. let's see the configuration on the router: Topology: Goal : configure the topology as per the diagram above. configure the IP addresses to their ports configure routing with EIGRP AS 65100 and advertise all the ports configure NTP on router 3, server address will loopback 0 make sure the rest of the routers get time which is provided by our NTP server.
