I just released a simple and practical introduction to the TCP/IP Model for anyone learning networking, CCNA, cloud, or cybersecurity. Understanding this model is essential for anyone building a career in tech. #TCPIP #Networking #CCNA #Cisco #Cybersecurity #Cloud #ITTraining #TechLearning #NetworkEngineering
