Hi Folks,
what is the right prep? ON source side... and ON target side or AT source side and AT target side (Remark: I'm takling of PC Systems. The Sender is the Source Side and the receiver the target side)
I would say either one is fine..."On" sounds a little more comfortable for me to use, but "at" is ok as well. "At" makes me think more of the physical aspect, like the environment of the target/source side.
Hope this helps!
