Elements of the Network Layer
This video explores the elements of the Network Layer, which is the OSI Model's third tier. The primary role of the Network Layer is to route datagrams across various subnetworks. What does it mean for the datagram transmission to be a connectionless message? Make sure you can distinguish between unicast and broadcast messaging. Ensure you know the function of routers when directing traffic between networks, the structure of datagrams (especially the header and the payload), which component carries the transmitted information, and the differences between the two prevalent Internet Protocol versions used today: IPv4 and IPv6.
