Describe the purpose of a proxy server.

A proxy server acts as an intermediary between a user's device and the internet, providing both privacy and security in various ways. When a user sends a request to access a website, rather than the request going directly to that website, it goes first to the proxy server. The proxy then forwards the request to the website and returns the response back to the user. This process helps to obscure the user's IP address, thereby enhancing privacy and anonymity online.

Furthermore, proxy servers can implement various security measures, such as filtering out malicious content, blocking access to certain sites based on predefined rules, and encrypting data to protect against interception. This makes them essential in organizational settings, where safeguarding sensitive information and controlling internet usage is crucial.

In summary, the role of a proxy server is key for users seeking to maintain their privacy online and for organizations striving to enhance security and manage internet traffic efficiently.
