Web hosting is an online service that allows you to publish your website or web application on the internet. When you sign up for a web hosting service, it provides a server where all the files that comprise your website (code, images, etc.) are stored and made available for viewing online. In other words, web hosting provides the necessary infrastructure and resources to store and run a website on the internet. A web hosting plan service typically provides a range of features such as storage space, bandwidth, domain name registration, email accounts, and security features to protect your website from hacking and malware attacks.
