Good Day,
I've been doing some reading and some sources say that csma/cd is what detects collision in a half duplex ethernet and others say its a loopback circuit. Which is it?
Thank You.

I think what you mean is CSMA/CD is only used in Half-Duplex communications, like 10 base ethernet and wireless. Full duplex communications do not use this technology because there all no collisions.
I am not sure what a loopback circuit is..Do you mean like a loopback tester or a loopback address (logical)? -

True. My mistake. It has been along one.

SB-K,
It's both.
