Communication between two computers (shown in grey) connected through a third computer (shown in red) acting as a proxy. Note that Bob doesn’t know whom the information is going to, which is why proxies can be used to protect privacy.
In computer networks, a proxy server is a server (a computer system or an application) that acts as an intermediary for requests from clients seeking resources from other servers. A client connects to the proxy server, requesting some service, such as a file, connection, web page, or other resource available from a different server and the proxy server evaluates the request as a way to simplify and control its complexity. Proxies were invented to add structure and encapsulation to distributed systems. Today, most proxies are web proxies, facilitating access to content on the World Wide Web and providing anonymity.
Δυστυχώς – όλοι οι τεχνολογικοί όροι δεν μεταφράζονται επακριβώς στα Ελληνικά και για αυτό, δεν θα πάρω το ρίσκο να μεταφράσω κάτι εσφαλμένα. Αρκετές περιπτώσεις ορολογίας θα παρατίθενται στην αγγλική γλώσσα.
