Clients and servers

A web client is any application that communicates with a web server utilizing HTTP. A web server is a computer that provides – or serves – web resources to web clients. A web resource is anything that provides web content. A web resource can be a media file, an HTML document, a gateway, and so on. Clients need web content for various purposes, such as information rendering and data manipulation.

Clients and servers communicate with each other via HTTP. One major reason for the utilization of HTTP is the fact that it is extremely reliable in data transmission. The use of HTTP ensures data loss does not occur in a request-response cycle.
