As mentioned by adam_pedley, cross-overs are primarily for use between switches, hubs, and routers. However, in recent years most home or small office devices are auto sensing, and will automatically adjust regardless of which cable you use. The rule of thumb is to connect a straight through cable, if the light on the device illuminates, indicating a connection, you are done. If not, you likely need a cross-over.

Cross over cables are for between devices such as hubs and switches.

Straight through are for between hubs/switches and end user devices such as computers

You will also find that most newer switches auto detect the cable type and adjust accordingly.

Hubs can also have a special link port in which you can press a button to change the port to accept a straight through cable for between the hub and a switch.

If you remember the days of null modem cables, you can make a decent analogy.

Yeah, pretty much. Crossovers are great for setting up quick peer-to-peer networks. And it's true that most newer devices are autosensing, but I still only use them for the purposes described above because of running into my share of devices that don't autosense.
