Learning Objectives

By the end of this lesson, learners should be able to:

1. Introduction

Every website on the internet needs an address and a place to store its files. The address is called a domain name, and the storage service is called web hosting. Most modern websites are managed using a Content Management System (CMS) that allows users to create and update content without advanced programming skills.

2. Meaning of a Domain Name

A domain name is the human-readable address used to access a website on the internet.

Examples

Instead of remembering numerical IP addresses, users type domain names into a web browser.

3. Parts of a Domain Name

Example: www.example.com

6. Domain Registration

To use a domain name, it must be registered through a domain registrar.

Registration Steps

  1. Search for availability.
  2. Select an extension.
  3. Provide registrant details.
  4. Pay the registration fee.
  5. Renew periodically (usually annually).

Failure to renew may cause the domain to expire.

7. Meaning of Web Hosting

Web hosting is a service that stores website files on a server connected to the internet so that users can access the website at any time.

Website Files May Include

  • HTML pages,
  • Images,
  • Videos,
  • Databases,
  • Scripts,
  • Documents.

The hosting provider maintains the server infrastructure.

8. How a Website Is Accessed

  1. User types a domain name.
  2. The browser requests the website.
  3. The domain name is translated into an IP address.
  4. The server sends website files.
  5. The browser displays the website.

This process happens within seconds.
