In serial data transmission, every byte of data is padded with a '0' at the beginning and one or two '1's at the end of the byte because

Consider three IP networks A, B, and C. Host HA in network A sends messages, each containing 180 bytes of application data, to a host HC in network C. The TCP layer prefixes a 20-byte header to the message. This passes through an intermediate network B. The maximum packet size, including a 20-byte IP header, in each network is: A: 1000 bytes, B: 100 bytes, C: 1000 bytes. The network A and B are connected through a 1 Mbps link, while B and C are connected by a 512 Kbps link (bps = bits per second). Assuming that the packets are correctly delivered, how many bytes, including headers, are delivered to the IP layer at the destination for one application message, in the best case? Consider only data packets.
