1. How "wide" is a bit on a 10Gbps link?

2. Assume that you want to send your Mom a picture file, continuously as one large message, over a link that has a rate of 1Mbps. You are studying at UMBC and she lives in Pakistan (assume 12000 km). If the propagation speed is the speed of light (3 * 10^8 m/sec), what is the maximum number of bits that will be in the link at any one time? (hint: bandwidth delay) Show your work.
