Mam one doubt mam in U frame N(R) represent sequence no.or acknowledgement?😊

[@preethij427]

In HDLC (High-Level Data Link Control), the U-frame (Unnumbered frame) is typically used for control purposes rather than carrying sequence numbers or acknowledgment numbers. It handles various control functions such as link setup, link disconnect, and flow control but doesn't include sequence numbers or acknowledgment information. Sequence numbers and acknowledgments are more commonly associated with I-frames (Information frames) in HDLC.
