"In simplified terms, a DNS (Domain Name Server) is like a phonebook that matches names to phone numbers. When you use an alphanumeric address such as www.cdh.ucla.edu, your computer needs to understand what numerical IP addresses it needs to contact to, and this is accomplished through DNS servers."
