Web hosting is the process of renting or buying space to host a website on the World Wide Web. It involves providing a fast connection to the Internet and storing and maintaining files for one or more websites. Website content, such as HTML, CSS and images, must be hosted on a server so that it can be viewed online. Web hosting services provide shared or dedicated hosting of one or more services for their customers.
These services are typically used to host websites, but they can also be used to host email, files, games and other company content. By outsourcing one or more core web-based functions to a hosting provider, companies can focus their resources on supporting their customers and growing their business.
