Answer the following questions:
1. (POGIL Activity 1) How does the geographical distance between the source and destination hosts on a network affect latency?
Answer
Geographical distance between the source and destination affects latency because the farther away geographically that the ping must travel between server and host, the longer (usually) it will take.
2. What are the benefits of packet switching?
Answer
The benefits of packet switching is that it can effectively send (relatively) small amounts of information between two hosts.
3. (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, an error detection should check, and then the message would have to be resent. The link layer would handle this situation if it were to arise. Additional information would be needed such as the sender and the intended recipient.
4. (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
As packets are being transmitted through the network, other people are able to read the messages other than the sender and receiver. Methods such as encryption and making sure that a secure network is being used can be used to protect the message.
