Multiple Choice Questions on Data Packet Routing for AP Computer Science

📚 Quick Study Guide

• 🗺️ Data packets are the fundamental units of data transmission over a network.
• 🚦 Routing is the process of selecting the best path for data packets to travel from source to destination.
• 🌐 Routers are network devices that forward data packets based on their destination IP addresses.
• 🔢 Routing algorithms determine the optimal path. Examples include Distance Vector and Link State.
• ⏱️ Key metrics used in routing include: hop count (number of routers a packet passes through), latency (delay), bandwidth (data transfer rate), and cost.
• 🛡️ Protocols like TCP/IP ensure reliable data transmission and address packet loss.
• 💡 Understanding IP addresses (IPv4 and IPv6) is crucial for grasping data packet routing.
