Which of the following describes a proxy server?

A proxy server is accurately described as a server that acts as an intermediary for user requests. When a client device sends a request for resources, such as web pages or files, the request is first sent to the proxy server. The proxy then forwards this request to the appropriate server on the internet, retrieves the data, and sends it back to the client. This process serves multiple purposes: it can enhance security by hiding the client's IP address, improve loading times through caching, and even enable access control or monitoring of web traffic.

The other descriptions do not capture the essence of what a proxy server does. One option mentions managing equipment, which is more aligned with network management devices rather than a proxy's primary function. Another option refers to distributing load, which is characteristic of load balancers rather than proxy servers. The last choice talks about an IP address assigned to a device, which pertains to IP configurations rather than the role of a proxy server in handling requests.
