Web hosting is a necessity for any website — it is the physical location of your website on the Internet, an online storage center that houses the information, images, video, and other content that comprises your website.
Web hosting service providers maintain the server where the data associated with your website resides, and also manage the technology that makes your website connect to the Internet.
A web host, or web hosting service provider, is a business that provides the technologies and services needed for the website or webpage to be viewed on the Internet.
Websites are hosted or stored, on special computers called servers. When Internet users want to view your website, all they need to do is type your website address or domain into their browser. Their computer will then connect to your server and your webpages will be delivered to them through the browser.
Most hosting companies require that you own your domain in order to host with them. If you do not have a domain, the hosting companies will help you purchase one.
Website hosting is typically measured in the amount of disk space you’re allotted on the server and the amount of data transfer or “bandwidth” you need for accessing the server. For example, if you have a lot of customer interaction at your website, such as files to download, you will access the server frequently and you’ll need more Web hosting transfer space than someone who simply puts readable text on their website.
The more “items” or “content” you have on your site (i.e., photos, maps, PDF files, etc.), the more disk space you’ll need for website hosting.
