I have a DSL modem connected to a four-port router/switch combo that has four ports on it. None of the cable is crossover and everything works fine. The super basic explanation of a switch is "a faster hub." It does everything that a hub does, only much faster (it allows multiple users to copy/send data at once through multiple data streams).
