I decided I would write this post when I was preparing for my Networks Exam. What happened was, there was this topic regarding the Error Control Mechanisms during Transmission of Packets. I was a little confused with the acknowledgment numbers and this is how I solved it.
Positive acknowledgement is followed by a number, which indicates the number of packets received (how many) and the number the next packet to be sent (which). Negative acknowledgement is followed by a number which indicates the packet which has to be retransmitted. When I read this sentence first, It was Greek and Latin to me, not anymore.
