6. A crossover cable has the send/receive lines "crossed over". That's important.

Some routers auto-sense and don't care what kind of cable you use, but if it is computer-to-computer, you MUST use a cross-over. You can tell by looking at the ends. The lines on a standard cable are the same. On a cross-over, 2&3 and 4&5 are reversed on the other side.

On Edit: Sometimes cross-over cables are called "uplink" cables because they are usually used to hook a router onto another one in the chain.
