Web Hosting is absolutely essential If you would like to have a website published online for the world to see. A common thought is that registering a domain name is all that is needed to have your website online. Yes, a domain name is an important part of the puzzle as this is the address your visitors will type into their browsers to access your site. Web Hosting, on the other hand, is what makes it possible for your web site to be accessed by your visitors.Web hosting is essentially the space you buy on a server that stores all the pieces that make up your websites. Once you your website is hosted by A2 Hosting, your visitors will be able to access your site by typing your domain name into their internet browser. Their computer is then connected with the server where your site is being hosted. The server then delivers the files that comprise your website to your visitors' browsers so they can view your site.
