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.

Answer 14

False. The Domain Name System (DNS) was developed to translate between IP addresses and domain names. Whenever you log your browser onto the internet and attempt to connect to a server using its domainname, the browser first communicates with a DNS server to learn the corresponding numeric IP address. The numeric IP address (and not the domain name) is encapsulated into the data packets and used by the internet protocol to route those packets from thesource to the destination.

Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.
