The answers are: -pc and router -router and hub -and wireless access point This question is confusing me because it seems to go against the table above. Plus, on my home network, I have straight-through cable for my dumb switch and AP and they work fine. The only time I have used crossover cable is when I wanted to connect two pcs together via their nics.
MDI Medium Dependent Interface. The name for the connector used to make a physical and electrical connection between a transceiver and a media segment. For example, the RJ-45-style connector is the MDI for 10BASE-T and 100BASE-TX.
MDI-X An MDI port on a hub or media converter that implements an internal crossover function. This means that a "straight-through" patch cable can be used to connect a station to this port, since the required signal crossover is performed inside the port instead of in the cable.

Chp 1 breaks down the following for straight-Through Vs crossover cable: Straight-Through -host to switch or hub -router to switch or hub Crossover Cable -switch to switch -hub to hub -host to host -hub to switch -router direct to host So now I have another question, if your connection a crossover cable to hub to hub, it needs to go into the uplink port/interface, correct? I reason I ask is that I've never worked with any of this equipment in the enterprise.
