Multiple Choice Questions on Network Simulation with Scratch

📚 Quick Study Guide

• 📡 Network Simulation: Creating a virtual representation of a network to study its behavior.
• 🐱‍💻 Scratch: A block-based visual programming language ideal for beginners to create simulations.
• 🧱 Sprites: The graphical elements (nodes, computers, servers) used in Scratch to represent network components.
• 🔗 Broadcasting: A Scratch feature allowing sprites to communicate and exchange data, simulating network traffic.
• 🚦 Variables: Used to store and track network parameters like bandwidth, latency, and packet loss.
• 📊 Data Visualization: Representing simulation results using charts or graphs within Scratch.
• 💡 Common Metrics: Understanding metrics such as throughput (data transfer rate) and response time are vital for analysis. Throughput = $\frac{Total \, Data \,Transferred}{Total \, Time}$
