Domain Name
Domain: Computer Systems
🎯 Motivation
A human-readable web address: google.com, cityu.edu.hk. Easier to remember than IP addresses.
📋 Concrete Example
Domain name: cityu.edu.hk. DNS translates it to an IP address. The browser connects to that IP. Domain names are human-friendly aliases for machine IP addresses.
🔗 Analogy
A domain name is like a person’s name - you say ‘call Alice’ instead of ‘call 9876-5432.’ Domain names are human-friendly labels for server IP addresses.
