You can choose a cheap affordable web hosting provider provided that you are not setting up a website that requires heavy usage of resources like CPU time, storage space or network bandwidth. Do look at the Terms Of Service with the Hosting provider. The Terms Of Service is usually located at the bottom of the web page.
How Shared Web Hosting works is that a group of clients share virtual space on the web server. How many accounts share this virtual space varies by host. Some host providers have a few hundred shared accounts on the same server, where as others have a few thousand. Also know as virtual hosting, Shared Web Hosting UK shares much more than just virtual web space on a server.
These hosting plans will usually provide only one root directory for all of the domains and sites you plan to build. You will also be allowed one "primary domain". All other domains will have to be "parked" or added on to the primary domain. Without getting too technical, let's just say that some Shared Web Hosting UK scripts don't "play" well with others. And many just don't like being installed in sub-directories!
A Registry is the company that looks after all the actual domain names, and because each Registry has so many millions of domain names under their control; they deal through Registrars.
Quick Affordable Web Hosting provides many benefits. Who likes to dwell and wait whilst a web page loads? It is said that a page must load in less than one second or you risk losing your website visitor. Websites are becoming increasingly sophisticated with images and sound as well as instant contact support, so your hosting really does need to be quick.
Support is so, so, so (getting where I'm going?) important when it comes to choosing a web host so make sure their tech support guys are available 24/7. The last thing you want is to be stuck waiting 24 hours before they can get back to you from the other side of the world.
This is why comparing different services provided by affordable web hosting providers is important. While other hosting companies lure potential customers with additional services, others simply make sure that your site is up and running and available to anyone who wants to visit them.
