On the web there are basically two types of computers (or more accurately, computer programs). A Server, whose job it is to serve web content. This service may include things like an HTML web page, a dynamic website with user specific contents like Facebook, web apps, or even APIs which programmers can use within other web services, like "Sign In with Google" which is used authenticate users across hundreds of web services. Point is, all of this services are provided what is known as a Server. It is the job of the server to listen for new requests, and give out appropriate response for the requests.

So, a proxy acts as a server that recieves all of the client's HTTP requests, and then it passes those requests onto whatever actual server the request was intended for. This can be used to obfuscate the true origin of the client, to filter out unintended requests in the case of a University or an Organization's network and for a lot of other purposes. A proxy can be used by one or more clients.

A reverse proxy is a proxy for one or more servers, and it acts as a gateway for all the incoming HTTP requests. It ensures that a request reaches its corresponding backend server, and not the wrong one. Of course, it also makes sure that response gets forwarded to the appropriate client as well.
