Computer A is sending a 10 MByte long file to Computer B via packet-switching over two consecutive 100 Mbps links of 2000 km length each. Assume that the signal propagation speed on both links is 2 x 108 m/s. Furthermore, assume that the maximum length of a packet is 1480 bytes and that Computer A fills each packet to the max, if possible. How many packets total will Computer A have to send out?
