Network Models Explained | OSI Model & TCP/IP Model | Computer Networking | BSCS

Welcome to Module 2: Network Models in this complete Computer Networking course. In this lecture, we explore the models used to understand how data moves between devices across a network. You will learn about the OSI Reference Model, seven layers of OSI, functions of each layer, TCP/IP Model, OSI vs TCP/IP, encapsulation and decapsulation, and Protocol Data Units (PDUs) such as bits, frames, packets, and segments. This lecture is designed for BSCS students, Computer Science students, beginners, and anyone learning Computer Networks. Understanding network models provides a strong foundation for studying protocols, IP addressing, routing, switching, transport protocols, and network security. 📚 Course: Computer Networking 🎓 Level: BSCS / Beginner 📌 Module: Network Models Topics Covered: • OSI Reference Model • Seven Layers of OSI • Functions of Each OSI Layer • TCP/IP Model • OSI vs TCP/IP • Encapsulation and Decapsulation • Protocol Data Units — Bits, Frames, Packets & Segments • Layer-to-Layer Communication #ComputerNetworking #NetworkModels #OSIModel #TCPIP #TCPIPModel #NetworkingBasics #ComputerNetworks #BSCS #ComputerScience #NetworkingTutorial #NetworkEngineering #CCNA #OSIvsTCPIP #Encapsulation #NetworkingCourse
