You didn't read his example well enough. He said, Say you have two
segments connected to a router; one segment off of e0 and one segment off
of e1. If a host on the e0 segment sends a frame to a host on the e1
segment and a collision occurs on the e1 segment before reaching the
destination
please clarify further? Thank you!

There is distinct difference between bit errors and collisions.

Sure, it's retransmit if there's a collision. Cut-through switching will
begin forwarding as soon as the MAC is read, but it must still keep a copy
in memory in case of collision. I guess I don't know for certain, but I
would assume...

You're right.
A bridge is not going to retransmit any frame that failed to reach it's
destination. That will be up to the appropriate protocol on the originating
host.

Regardless of whether a router is configured for bridging or routing, it
must send an Ethernet frame successfully, without a collision. A
half-duplex Ethernet interface (whether on a bridge, switch, router,
server, or PC) monitors for a collision while sending. If a collision
occurs, the
I agree with you transparent bridges are just that, transparent. Any
retransmittal of corrupt or lost frames would need to be done by the end
station AFAIK, (with ethernet) even if a device receives a corrupt
frame, at layer 2, it simply discards it it doesn't request
retransmittal
If an Ethernet device receives a damaged frame, it silently discards it.
That is true. But a half-duplex Ethernet sender knows when a collision
occurs with a frame that is sending and retransmits. That's the CD part of
CSMA/CD.
If a frame got damaged for some other reason, say noise or
I'm doing my written tomorrow, I've studied that retransmits are part of the
Host's job, especially in a TB network. TB's are stupid, they do no error
recover or anything similar.
You are correct
