Web hosting is a service that allows individuals and organizations to make their websites accessible on the Internet. It involves storing website files and data on servers, which are powerful computers connected to the internet. These servers host and deliver the website's content to users when they type the domain name into a web browser. Web hosting providers offer various plans with different features and resources to accommodate the needs of website owners. Key aspects include server reliability, speed, security, and support. Choosing the right web hosting service is crucial for ensuring a website's performance, accessibility, and overall online presence.
