What is Web Hosting?
Web hosting is a service that allows individuals and organizations to host their websites on the Internet. It involves renting space on a server, where website files such as HTML, CSS, images, and scripts are stored and made accessible to visitors via the World Wide Web.
Types of Web Hosting Services
There are several types of web hosting services available, each catering to different website requirements and budgets. The most common types include shared hosting, virtual private server (VPS) hosting, dedicated server hosting, cloud hosting, managed hosting, colocation hosting, and reseller hosting.

How Web Hosting Works
When a user enters your website’s URL into their browser, the browser sends a request to the server where your website is hosted. The server then processes the request and sends the necessary files back to the browser, allowing the user to view and interact with your website.
Web hosting providers maintain and manage the server infrastructure, ensuring that your website remains accessible and runs smoothly. They also provide additional services such as domain registration, email accounts, and website-building tools.

Domain Names and DNS
What is a Domain Name?
A domain name is a unique address that identifies your website on the internet. It consists of a series of characters separated by dots, such as “example.com.” Domain names are used instead of IP addresses, which are difficult to remember, making it easier for users to find and access your website.
Image: A diagram showing the components of a domain name, e.g., top-level domain (TLD), second-level domain, and subdomain.
Domain Name Registration
To use a domain name for your website, you need to register it with a domain registrar. Registrars are companies authorized to sell and manage domain names. During registration, you choose a unique domain name and pay a yearly fee to maintain ownership.
