This video lecture explains the different types of network topologies namely Ring topology, Bus topology,Star topology and Mesh topology. It also explains the advantages and disadvantages of each network topology.

Network Types [LAN, MAN, WAN & Wireless]

This lecture video explain the different types of computer networks viz. Local Area Network, Wide Area Network, Metropolitan Area Network and Wireless Networks.

OSI Reference Model [7 layers explained]

This video explains one of the most important communication model of computer networks, the OSI Reference Model. We discuss the 7 layers of OSI Reference model and also some example protocols of each layer.

TCP/IP Protocol Suite

This video explains the TCP/IP Protocol Suite (TCP/IP Model) in detail. We provide an overview of the functionalities of the 4 layers and discuss different protocols present in each of these 4 layers of TCP/IP Protocol Suite.

Network Performance [Bandwidth, Latency, Error rate, Jitter]
