(POGIL Activity 1) How does the geographical distance between the source and destination hosts on a network affect latency?
Answer
Latency is affected by distance because the signal needs to travel a large distance to the host and so takes a while.
What are the benefits of packet switching?
Answer
A benefit of packet switching is that it helps make data less vulnerable from being interfered with while it is being sent.
(POGIL Activity 2) Missing Packets. What should happen if a packet goes missing? Who (which layer) would handle this? What action would they have to take? And what additional information would be needed in the packet in order to handle it?
Answer
If a packet goes missing, you'll have to resend it. The link layer is responsible for handling it. An action that they would have to take is making a copy of it and info about sending it to where.
(POGIL Activity 2) Security/Privacy. As the packets are being transmitted through the network, can people other than the sender and receiver read the messages? What methods can we use to protect the message?
Answer
YEs, people can still look into the messages because the message is also going through them openly with nothing covering it so anyone could read it. To protect against this, encryption can be used to the messages from being seen.
