Domain Names
Domain names are human-readable addresses used to identify and locate resources on the internet, such as websites or email servers. They translate into numerical IP addresses through the Domain Name System (DNS), making it easier for users to access online services without memorizing complex numbers. Domain names are structured hierarchically, with top-level domains (TLDs) like .com or .org, and are registered through accredited registrars.
Developers should understand domain names when building web applications, configuring servers, or managing online infrastructure, as they are essential for deploying and accessing websites and services. Knowledge is crucial for tasks like setting up DNS records, implementing SSL/TLS certificates, and ensuring proper routing and security for domains. It's also important for SEO, branding, and managing multi-domain architectures in cloud environments.
