A web host is a service provider that places your web site on a computer which is connected to the internet. All websites are hosted on computers (called web servers) all over the world. Web servers store all of your web site's html files, graphics, video and other content, and make them accessible to anyone wishing to access your site.
Web hosting companies can look after every aspect of your hosting needs, including uploading your content to a shared server, ensuring a constant, fast connection to the Internet, and regularly backing up all your website as it evolves.
Web hosts usually charge on a monthly basis and provide differing levels of service. They offer a range of plans, from your budget to your more comprehensive, high data storage, high bandwidth, high visitor volume plans. You can make significant savings to your website costs by reviewing your existing plan and investigating the other types of plans available on the market.
