A straight cable is just that. Each pin (contact) on one end is connected to the same pin on the other end. A cross-over cable is wired so that this is not the case, so the transmit pin on one end is connected to the receive pin on the other, and vice-versa. Before computers and switches had smart connectors that can adjust to the cable type, it was necessary to use a cross-over cable to connect one computer directly to another - what may be called DTE (Data Terminal Equipment) to DTE. If connecting a DTE (computer or terminal) to a DCE (Data Communication Equipment) such as modem, switch, etc, then a straight cable is used. However, as I mentioned, most modern equipment doesn't care any more since the electronics are "smart" enough to adapt to whatever cable is being used.
