Function of flags in frames

[vedaprabhu]

Dont you think a single flag to mark the start of frame is sufficient instead of having an end flag also?single flag can mark the beginning of next frame and end of first frame.Right?!

Flags in frames

frames are not usually sent back-to-back specially in case an ACK is required

Re: Flags in frames

If u send the packet with one flag at the begining , how receiver will now end of the data since reciever continues recieve the one which is due to noise, isnt it?. to mark end of the frame we use flag at two ends

Re: Flags in frames

i guess it is end arround logic?
Do i stand corrected?
