| SERVER | A computer that awaits and responds to requests for data Example: a DNS server awaits and responds to requests for URLs to be translated to IP addresses. |
| CLIENT | A computer that requests data stored on a server Example: When you type an address into your browser, your computer is the client and it sends the request to the DNS server. |
