Multiple Choice Questions on Domain Names and DNS for Grade 7

📚 Quick Study Guide

• 🌐 Domain Name: A human-friendly address for a website (e.g., google.com). Think of it as the website's street address.
• 🔢 IP Address: A numerical label assigned to each device connected to a computer network that uses the Internet Protocol for communication (e.g., 192.168.1.1).
• 🏘️ DNS (Domain Name System): A phonebook for the internet. It translates domain names into IP addresses so browsers can load internet resources.
• 🔄 DNS Resolution: The process of finding the IP address associated with a domain name.
• 🔑 Top-Level Domain (TLD): The last part of a domain name (e.g., .com, .org, .net).
• 💡 Subdomain: A domain that is part of a larger domain (e.g., mail.google.com, where 'mail' is the subdomain).
• 🛡️ Importance of DNS: Without DNS, we would have to remember long strings of numbers (IP addresses) to access websites.
