Web hosting is a service that allows individuals and organizations to make their websites accessible via the World Wide Web. In essence, it involves storing the files and data of a website on a server connected to the internet, making it accessible to visitors around the globe.

A good web hosting service provides the infrastructure and technology necessary to ensure that websites are available and functional 24/7. This includes server maintenance, security measures, technical support, and various features such as email hosting, database support, and website building tools.

Web hosting can vary in terms of the type of server used, the level of resources allocated (such as disk space, bandwidth, and processing power), and the level of technical support provided. Some common types of web hosting include shared hosting, virtual private server (VPS) hosting, dedicated server hosting, and cloud hosting.
