True or False 1. A streaming video (UDP) from video server to a subscriber's PC at 300 Kb/s capacity with download latency of 40 ms delay could be considered a bidirectional flow. 2. A transaction processing from point-of-sale machine to server with upstream data (from PoS machine to server) at 30 kb/s and downstream data at 50 kb/s assuming 100 ms round-trip delay is a bidirectional flow. 3. There are generally two flow models, composite and individual.
