ASL STEM

Definition

a computer that saves information acquired from elsewhere on the INTERNET and makes it available to other computers in its immediate area. For example, if several users connect to the same WEB SITE through a proxy server, each page of information will be downloaded from that site only once and then provided to all the users. A disadvantage of proxy servers is that they make it impossible to count HITs accurately.
