Explain what is meant by the term 'hosting' and how it is used in web development.

Hosting is a service that provides server resources for hosting websites, applications, or other internet services so that they are accessible to users via the Internet. In web development, hosting is used to store website files (HTML, CSS, JavaScript, images, etc.) and ensure their availability through a domain name.

Example: you developed a website using Node.js and want users to be able to open it in their browsers. For this, you host your project on a hosting service — a server with a constant internet connection, where your website will operate 24/7.
