Answer 18

False. A proxy server is often used to improve the communication speed of computers inside of a company with the Internet at largeoutside the company. For example, if ten people inside the company attempt to connect to the same Internet server and download the same web page within a (hopefully) short period of time, that page may be saved on the proxy server on the first attempt and then delivered to the next nine people withoutre-acquiring it from the outside web server. This can significantly improve delivery time and reduce network traffic into and out of the company.
