how to reduce collision

the references section needs some cleanup, it doesn't fit wiki standards.

Collision detection is not done by CRC

The article implies that collision detection is based on CRC. This is incorrect. It is an analog process -- the transceiver monitors the wire while it is sending, and if it detects a signal on the wire that differs from what it sent (because another transceiver is also contributing) that is a collision.

Collision detection is a physical layer function. CRC handling is a MAC layer function. The two are not connected.
