16.2. DNS

16.2.1. Like a phone book of IP adresses

16.2.2. Your computer dosn't know all the IP addresses, so it uses DNS, which translates ULRs into ip addresses

16.2.3. Similar to making a phone call, as you find the place you want to call, turn it into a phone number, and call it.

17. 17. Validating Identities Online

17.1. Extended Validation Certificates
