TCP's structure emphasizes the importance of precision and veracity in any modern network, from opening a connection through SYN, SYN-ACK, and ACK to a clean finish through FIN and ACK.  💡 Highlights: - **Three-Way Handshake** ensures a secure and synchronous connection.   - Reliable **Data Transfer** guarantees message integrity.   - **Four-Step Connection Termination** does a clean closure without losing data. Everyone in networking, cybersecurity, and beyond should have knowledge of these concepts!  🔗 I'm eager to put this knowledge to use in real-world scenarios and build up my experience further again.  #Networking #TCP #CyberSecurity #TechLearning #GrowthMindset  

Finishing the "Networking Core Protocols" module feels like unlocking a critical layer of understanding about how the internet truly works. This module dives into the protocols that form the backbone of communication across networks, such as TCP/IP, UDP, and ICMP. These are not just technical acronyms but the lifelines that enable data exchange in our interconnected world. One of the most rewarding aspects of this module was demystifying the flow of data. Understanding how TCP ensures reliable delivery with its handshake mechanism, or how UDP sacrifices reliability for speed, adds a new layer of appreciation for different applications' needs. Similarly, ICMP's role in diagnostics and error reporting through tools like ping and traceroute has practical, everyday relevance for troubleshooting. What stands out is how this knowledge strengthens both theoretical and practical networking skills. From analyzing packet structures to understanding protocol-specific behavior, I now feel more equipped to handle real-world networking challenges. This module is not just a stepping stone but a solid foundation for exploring more advanced topics in cybersecurity and IT. As I reflect on this achievement, I look forward to applying this knowledge in scenarios that require a sharp eye for network details. Whether it's for penetration testing, network troubleshooting, or even optimizing performance, these core protocols are a critical part of my cybersecurity journey. TryHackMe

#Day26 of the TryHackMe #100dayschallenge and I've completed the room of Packets and Frames. This room has cleared up some misconceptions I had about the differences between Packets and Frames and why TCP/IP and UDP/IP and different as well. The room covers Frames vs Packets , TCP/IP , the 3-way handshake , UDP/IP , and some common ports. Learning summary: - Packets and Frames are both used in combination to create large pieces of data or "Messages" , this means even though their different , their both used via the encapsulation completed during the OSI Model from Layer 3 (Networking) to Layer 2 (Data-link). - Frames strictly deal with all things related to MAC addresses , and add the source and destination MAC addresses to the Packet from layer 3. Meaning the packet from layer 3 is encapsulated in a data frame and has MAC address information added to it. - Packets strictly deal with anything related to IP Addresses only , the packet contain headers necessary to the routing of the data to the target device. - The TCP/IP Model is similar to the OSI Model but the TCP/IP Model only contains 4 layers of Application , Transport , Internet , and Network Interface. TCP/IP is considered to be the summarized version of the OSI Model. Encapsulation still occurs in TCP/IP. Day 26 Complete. #TryHackMe #Cybersecurity #Infosec #Ethicalhacking #Learning #Networking
