Computer A uses Stop and Wait ARQ to sand packats to computer B. If the distance between A and B is 40000 km the packet size is 5000 bytes and the
bandhvidth is 10Mbps. Assume that the propagation speed is 2.4x108mis?

-How long does it take computer A to receive acknowledgment for a packet ?

1. which of the following statements are true about routers and routing on the internet. choose two answers. a. protocols ensure that a single path between two computers is established before sending packets over it. b. routers are hierarchical and the "root" router is responsible for communicating to sub-routers the best paths for them to route internet traffic. c. a packet traveling between two computers on the internet may be rerouted many times along the way or even lost or "dropped". d. routers act independently and route packets as they see fit.
