Basically, the CSMA/CD algorithm can be summarized as follows:
- A device that wants to send a frame waits until the LAN is silent–in other words, no frames are currently being sent–before attempting to send an electrical signal.
- If a collision still occurs, the devices that caused the collision wait a random amount of time and then try again.

Explain the Ethernet Straight-Through Cable Concept
An Ethernet Straight-Through cable connects the wire at pin 1 on one end of the cable to pin 1 at the other end of the cable the wire at pin 2 needs to connect to pin 2 on the other end of the cable; pin 3 on one end connects to pin 3 on the other; and so on. (To create a straight-through cable, both ends of the cable use the same EIA/TIA pinout standard on each end of the cable.) A straight-through cable is used to connect dissimilar devices to one another.
Explain the Ethernet Crossover Cable Concept
You swap pins 1/3 and 2/6. A crossover cable is used to connect similar devices to one another.
