Multiple Choice Questions: Bandwidth and Latency for Computer Science Students

📚 Quick Study Guide

• 📶 Bandwidth: The maximum rate of data transfer across a network connection. Measured in bits per second (bps), kilobits per second (kbps), megabits per second (Mbps), or gigabits per second (Gbps). Higher bandwidth means more data can be transmitted simultaneously.
• ⏱️ Latency: The time delay in data transfer over a network. Measured in milliseconds (ms). Lower latency means faster response times.
• 🧮 Bandwidth vs. Latency: Think of bandwidth as the width of a pipe and latency as the time it takes for water to flow through it. A wider pipe (higher bandwidth) allows more water to flow, and less time (lower latency) means faster delivery.
• 🌐 Factors Affecting Bandwidth and Latency: Distance, network congestion, hardware, and transmission medium all impact bandwidth and latency.
• 🔗 Relationship: Bandwidth and latency are independent. High bandwidth does not guarantee low latency, and vice versa.
