Define Character Stuffing?

3.	What is Bit Stuffing?
	Answer: Bit stuffing is the process of adding one extra 0 whenever five consecutive Is follow a 0 in the data, so that the receiver does not mistake the pattern 0111110 for a flag. Workspace Report errors ... Name : Email: View Answer

4.	What is Flow Control?

9.	What is usage of Sequence Number in Relaible Transmission?
	Answer: The protocol specifies that frames need to be numbered. This is done by using sequence numbers. A field is added to the data frame to hold the sequence number of that frame. Since we want to minimize the frame size, the smallest range that provides unambiguous communication. The sequence numbers can wrap around. Workspace Report errors ... Name : Email: View Answer
