Shared web hosting is what most people mean when they refer to “web hosting”.  It simply means that many customers’ websites reside on a single web server, and that the server’s resources (CPU and RAM) are shared among every customer account on the machine.  It constitutes a means to host your site without having to be much informed about programming and handling a web server.  In addition, it’s also the cheapest form of web hosting and it’s indeed affordable for everybody.  Customers who do not need the flexibility of a Virtual Private Server or the performance of a Dedicated Server greatly benefit from what shared web hosting offers.
