A router and a separate server., D. A switch and multiple network cables for each computer, During the Packet Simulation Activity, your group sends a long message, but the packets travel on different routes. If one packet gets lost, what is the most logical reason that the entire message does not need to be resent?, A. The sender's computer automatically detects the loss and retransmits only the missing packet., B. The internet's main router has a backup of the message and sends the lost packet itself., C. The recipient can guess the missing part of the message using the surrounding packets., D. All packets are retransmitted from the beginning, but the process is so fast that you don't notice., Imagine you and a friend are playing a video game online. You both have a fast internet connection, but sometimes your game "lags" and appears to freeze. Based on your knowledge of the TCP/IP protocol, which statement best explains why this might happen?, A. The game's data packets are being sent through a different path than your video chat packets, causing them to arrive at different times., B. TCP is designed to prioritize video and voice data over game data, leading to delays for your game packets., C. Your computer is waiting for confirmation that a game packet has been received before sending the next one, which causes a pause when a packet is delayed., D. The IP protocol is not working correctly, causing all your data to be sent to the wrong network., Packets can take different paths to reach their destination. What is the most significant advantage of this "packet switching" approach if a major internet cable in your city is accidentally cut by construction workers?, A. All internet traffic in your city would shut down completely until the cable is fixed., B. All data packets would be lost, and all messages would fail to send., C. Routers would automatically reroute the packets along alternate, functioning pathways., D. Only the messages from computers directly connected to the cut cable would be affected., Your teacher sends the class a large file. A few moments later, your computer says the file is corrupt and needs to be downloaded again. Based on the lesson, what is the most likely cause of this issue?, A. The file was so large that it could not be sent as packets., B. The TCP protocol detected an error in a few packets and requested their retransmission., C. The TCP/IP protocols failed, and the internet connection was lost completely., D. The network was too fast, causing the packets to arrive out of order and become scrambled., You and your friend are building a scale model of the internet using toy cars and roads. Your friend suggests using one single road that all cars must use, while you suggest creating many different smaller roads that connect to each other., A. It guarantees that all the cars will arrive in the correct order every time., B. It ensures that if one road is blocked, all cars can still find a different way to their destination., C.
