Answer
The laptop’s performance is lower in the bedroom due to the distance from the wireless access point in the kitchen. Greater distance can lead to signal degradation and reduced data transfer rates. Additionally, obstacles such as walls may further weaken the signal.

Answer
Hope's network uses a peer-to-peer model because devices can communicate directly with one another without needing a central server. This allows for easier file sharing and reduced dependency on a single point of failure, making the network more resilient.
