1. (POGIL Activity 1) How does the geographical distance between the source and destination hosts on a network affect latency?
    The geographical distance between the source and destination effects latency because the signal has more miles to travel, which will take more time.
  2. What are the benefits of packet switching?
    Packet switching makes data less vulnerable to interruption because if you take one router out, there are still more routers available for use. In addition, the Internet can grow more if more routers are available to use, as it alleviates pressure from one individual router.
  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?
    If a packet goes missing, it has to be resent. The link layer is responsible for retrieving it again. and they should go back to the source and get another copy. It would need the identifying information so that it could be resent to the location of the rest of the packets.
  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?
    Packets are being transmitted through the network, and people other than the sender and receiver can read the messages. This is why encryption is so significant.
