Straight-through - Connect PC to hub or switch (router to switch or hub)
Crossover - Connect hub to hub/ switch to switch/PC to PC
Rolled - Console connection for PC to router
Half Duplex Ethernet shares a collision domain resulting in lower throughput than Full
Duplex Ethernet which requires a point-to-point link between two compatible nodes
Causes of LAN congestion - Broadcast storms, too many hosts with a broadcast
domain, multicasting, low bandwidth, bottlenecks
Collision domain - Switches/bridges breakup collision domains, hubs extend them
Broadcast domains - Routers and VLANs breakup broadcast domains
