A domain name is a unique name that identifies a website. For Example Domain Name of Om techno, is 'omtechno.in'. Each website has a domain name that serves as an address, which is used to access the website. Whenever you visit a website, the domain name appears in the address bar of the web browser.
Some domain names are preceded by "www" (which is not part of the domain name), while others omit the "www" prefix. All domain names have a domain suffix, such as .com, .net, or .org. Suffix are Known as Domain TLDs.
Domain names are relatively cheap to register, though they must be renewed every year or every few years.
The good news is that anyone can register a domain name, so you can purchase a unique domain name for your blog or website.
