Most people understand “www” in a web address, means World Wide Web, but is the “www” really necessary?
Many domain names used for the World Wide Web begin with www because of the long-standing practice of naming Internet hosts (servers) according to the services they provide. The hostname for a web server is often www, in the same way that it may be ftp for an FTP server, and news or nntp for a USENET news server. – Wikipedia
Sapphire Solutions owns the domain sapphiresolutionsltd.com and if we named the internet hosts according to the services they provided, we would have:
- A Web Site at www.sapphiresolutionsltd.com
- A FTP site at ftp.sapphiresolutionsltd.com
- A NEWS site at nntp.sapphiresolutionsltd.com
