Udemy – Domains, Hosting & DNS Explained for Beginners 2025-9

Domains, Hosting & DNS Explained for Beginners. This course explains the basic concepts of domains, hosting, and DNS in a simple and practical way for beginners. Understanding how the Internet works and the technical terms associated with it are often challenging for beginners, and this course is designed to create a clear and understandable knowledge base. First, a domain name and its role as a website’s Internet address are examined, and the types of domains and their registration process are taught. Then the concept of hosting as a space for storing site files is explained, and its different types, including shared hosting, virtual server, dedicated server, and cloud hosting, are compared, along with the advantages and disadvantages of each. Next, the Domain Name System or DNS is introduced, which, like a phone book, translates domain names into server IP addresses. The types of DNS records such as A, CNAME, MX, and NS and the role of each are explained in simple language. Finally, the course provides a hands-on demonstration of how these three components come together to create a website. It also covers practical issues such as site migration, email setup, and managing DNS changes so that students can confidently manage their own website.
