[Computer Networking] Hosts A and B are each connected to a switch S via 100-Mbps links as below Figure 1. The propagation delay on each link is . S is a store-and-forward device; it begins retransmitting a received packet after it has finished receiving it. Calculate the total time required to transmit 10,000 bits from A to B in the following cases:

1. When all the 10,000 bits are transmitted in a single packet.

2. when the 10,000 bits are transmitted in two 5000 bits packets sent one right after the other.
