Web hosting is a service that allows individuals and organizations to make their websites accessible via the World Wide Web. Essentially, it involves storing your website's files and data on a server, which is connected to the internet. When someone types your website's domain name into their web browser, the browser sends a request to the server where your website is hosted, and then the server responds by delivering the requested web pages to the user's browser.

Web hosting companies provide the technology and infrastructure needed to keep websites accessible 24/7. They offer various types of hosting plans, including shared hosting, dedicated hosting, virtual private server (VPS) hosting, and cloud hosting, each catering to different needs and budgets. Additionally, web hosting services often include features like domain registration, email hosting, website builders, security measures, and technical support to help users manage and maintain their websites effectively.
