Why do some websites still use “www.” before their domain name and some simply don’t? What’s the purpose of it anymore?
The "www" is what's termed a "subdomain". Originally, the "www" (which stands for "world wide web") was used to indicate that you wanted the web server for the domain you entered in, as opposed to something like their FTP server. Subdomains are still used today.
The Short Answer
The "www" is what's termed a "subdomain". Originally, the "www" (which stands for "world wide web") was used to indicate that you wanted the web server for the domain you entered in, as opposed to something like their FTP server. Subdomains are still used today. For example, you can go to "_URL_1_" to get to Google Maps, or "_URL_0_" to get to gmail. But generally it's assumed that if you don't specify any subdomain, you're probably interested in the domain's main webpage, which is what the www is for, so it's often redundant, and thus not required.
