... Why Framing? • When node A wishes to transmit a frame to node B, it tells its adaptor to transmit a frame from the node’s memory. This results in a sequence of bits being sent over the link. • The adaptor on node B then collects together the sequence of bits arriving on the link and deposits the co ...
