What is the purpose of the SVI on a Cisco switch?

The SVI provides a virtual interface for remote access to the switch.*

A technician with a PC is using multiple applications while connected to the Internet. How is the PC able to keep track of the data flow between multiple application sessions and have each application receive the correct packet flows?

The data flow is being tracked based on the source port number utilized by each application.*

An Internet television transmission is using UDP. What happens when part of the transmission is not delivered to the destination?

The transmission continues without the missing portion.*
