A server is another name for a computer. In this case, a system or group of apps that act(s) as a sort of go-between for other computers on a a network (or internet). The other computers are referred to as "clients." A client connects to the proxy server, requesting information (a file, a connection another computer, access to a web page, etc) that is available from a different server or computer. The software on the proxy server establishes whether or not you (the client) are allowed to have/view what you're requesting, and if it's allowed, connects you. On the Internet, proxy servers are mostly used to keep the computers behind it anonymous. They are also sometimes referred to as gateways.

In computer networks, a proxy server is a server (a computer system or an application program) 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. The proxy server evaluates the request according to its filtering rules. For example, it may filter traffic by IP address or protocol. If the request is validated by the filter, the proxy provides the resource by connecting to the relevant server and requesting the service on behalf of the client. A proxy server may optionally alter the client's request or the server's response, and sometimes it may serve the request without contacting the specified server. In this case, it 'caches' responses from the remote server, and returns subsequent requests for the same content directly.

to stay anonymous on the internet - websites can exactly see what ip address you have got so to hide it you can use proxy server
