- 1Can you know in advance the path a message will take between you and another computer on the Internet?No, since the fastest route is always changing. If the message gets slower in that route, it then changes routes to a faster route. Its a complicated process but we can never know which path our messages go.
- 2Describe the relative benefits of routing over a broadcast style of communication. Is routing traffic more secure than broadcasting?Routers will always only send messages to specific devices while broadcasting will send it to many. Therefore it is much easier with a router, unless someone gets access to your router.
