Question

ont Paragraph Styles Question 4 (25 Marks) Consider a communication link connecting a source machine A to a destination machine B. The sender A operates at a bit rate of 100 kbps. Assume that 1 bit out of 2 x 106 bits arrive to B in error. The data are sent over this link in frames of size 2000 bits. If you know that the communication link is used continuously over two hours. Is it possible that only one frame be received at B with errors during that time? Justify your answer with calculations. nglish (United States) earch

Answer 1

Data Rate @ A = 100 kbps So, No. of bitt sent over channel for - 2 hours = 100x103/ 60x60 sees y = 7.2X108 bits Now, on 2x100 bits, & it is in error so, in 7.21108 bits, no of bits in errona 7.28108 2x lor = 360 bitt Now, bits are sent over in frames of 2000 bits 1. so frames having 2000 bits . If we consider all the 360 bits that are in erron are belonging to some frame, as no of bith in erson ress them frame size. So we can say it is possible that only one frame is error in Scanned with CamScanner
