CS402: Computer Communications and Networks

While watching this video, focus on understanding network devices and their functions. How do devices like hubs, repeaters, concentrators, and amplifiers extend data transmission distances within specific network domains? Modems convert digital to analog signals. Bridges facilitate traffic forwarding based on MAC addresses and network connectivity between topologies. Switches reduce collision domains and direct packets using MAC addresses, while advanced switches enhance security and routing capabilities. Routers connect networks and use routing protocols to determine data paths. Network segmentation limits exposure to threats and controls movement within the network.
