📡 Day 9 – Networking IP address = how data finds the right device on the internet. IP Datagram = packet used to send data. Datagrams are path-independent but unreliable no guarantee against packet loss,duplication, reordering, or corruption. #CyberSecurity #Networking #TCPIP

📡 Day 8 – Networking OSI = 7 layers, reference model. TCP/IP = 5 layers, real internet stack. OSI doesn’t map cleanly to protocols. TCP/IP is protocol-driven. Know the stack. Know the attack surface ⚔️ #CyberSecurity #Networking #InfoSec #TCPIP #OSIModel #LearningInPublic

💔

📡 Day 7 – Networking Learned about Headers how layers keep adding them from sender to receiver and strip them off at the destination.Studied the TCP/IP model, the real internet architecture.5 layers, where Application = Application+ Presentation + Session (OSI).#CyberSecurity

📡 Day 6–Networking Learned the OSI Model (reference, not implemented). 7 layers in action: Application (services)→Presentation (format/encode)→Session (initiate/manage)→Transport (segment & reassemble)→Network(path selection)→Data Link (framing)→Physical(bit transmission).

Name a topic, and I'll share the best GitHub repository to learn it!

📡 Day 5 – Networking Learned Switching Types • Message Switching – whole message stored at intermediates • Circuit Switching –dedicated physical path, no storage • Packet Switching – data split into packets Understanding how data moves before intercepting it ⚔️#CyberSecurity

📡 Day 4 – Networking Learned about Transmission Media. Guided vs Unguided. Focused on Guided media: Twisted Pair, Coaxial Cable & Optical Fiber. Understanding the physical layer before attacking the network ⚔️#CyberSecurity #Networking #EthicalHacking #RedTeam #BugBounty

📡 Day 3 – Networking Learned core network devices: Hub, Repeater, Modem, NIC (MAC address). Switches = intelligent forwarding (no flooding). Bridge, Router & Gateway (software-based). WAP connects wireless devices to wired networks.#CyberSecurity #Networking #EthicalHacking

📡Day 2 – Networking • Internet is owned by no one • WAN = collection of LANs • You can own a LAN, ISP provides internet access • Gateways enable network-to-network communication • DSL & Cable Modems =broadband(download > upload) #CyberSecurity #Networking #EthicalHacking

🚀 Networking – Day 1 Complete! Learned how networking connects devices so they can communicate & share resources.Covered core concepts like LAN, MAN, WAN and network topologies such as Star, Ring & Bus. Foundation set. More to come 🔥#Networking #CyberSecurity #BugBounty

Hey Guys Long time no see !! 😊 it's been 4-5 days since I am Learning About Networking, It is one of the core Things you need to excel in CyberSecurity, I will Share my learning with all of you people From Tomorrow Until Then Stay Tuned!! 🔥
