Multiple Choice Questions: Understanding Networks, Nodes, and Connections

📚 Quick Study Guide

• 🌐 Network: A group of interconnected devices capable of exchanging data. Think of it like a web of computers, servers, and other gadgets all talking to each other.
• 📍 Node: A connection point within a network where data can be created, received, or transmitted. It's basically any device connected to the network.
• 🔗 Connection: The physical or logical link between two or more nodes in a network, enabling communication. Could be a cable or a wireless signal!
• 📡 Network Topologies: The arrangement of nodes and connections in a network, such as bus, star, ring, mesh, and tree. Each has its own pros and cons.
• 🚦 Protocols: Sets of rules governing data communication within a network, ensuring devices can understand each other. Examples include TCP/IP, HTTP, and FTP.
• 📐 Bandwidth: The amount of data that can be transmitted over a network connection in a given amount of time, usually measured in bits per second (bps).
• 🔒 Network Security: Measures taken to protect a network and its data from unauthorized access, use, disclosure, disruption, modification, or destruction.
