Why does Weblinks starts with www?

• WWW means World Wide Web.
• It lets people know that they are opening a web resource or web files.
• Its not compulsory to add the www nowadays.

[earn] Websites usually start with "www" because, back in the days, it was just the way of telling everyone, "This text is a website link." That "www" (World Wide Web) used to help people and computers know they were entering the web, unlike “ftp” which was for file stuff and “mail” for email.

Web servers store resources by IP addresses, which look like “12.34.56.789.” To make websites easy for people to remember, a system was created to translate these IPs into names like “www.pafbig.com.” This way, while you use the easy-to-remember web address, the server sees the numeric IP behind the scenes and fetches what you need. So, remembering “pafbig.com” is all you need to visit us anytime, and the computer handles the rest!

These days, though, adding "www" is not really compulsory again. Most websites now work whether you type "www.example.com" or just "example.com"—they both take you to the same page. Na DNS (the network setup) makes it possible for both versions to work smoothly without stress. [earn]
