What does www?
mean
When we surf the internet, it is common to come across the prefix “www” before the name of a site. But do you know what that means?
www is the acronym for World Wide Web, which in Portuguese means “worldwide range”. This is an interconnected and accessible document system through the internet.
A World Wide Web was created by Tim Berners-Lee in 1989 to facilitate information sharing between network connected computers. It is made up of a vast amount of web pages, which may contain texts, images, videos, links and other multimedia elements.
How does the World Wide Web?
World Wide Web works through the HTTP (Hypertext Transfer Protocol) protocol, which allows information transfer between servers and customers. When we type a website address in the browser, the browser sends a request to the server where the site is hosted, and the server responds by sending the necessary files to display the web page.
Wide Web Wide Website addresses are identified by URLs (Uniform Resource Locators), which start with the prefix “www”. For example, the address of a fictional site called “example.com” would be “www.exemplo.com”. However, it is important to note that not all sites use the prefix “www” at their addresses.
The importance of www
The prefix “www” has become so popular that many people consider it essential when entering a website address. However, it is important to highlight that the use of “www” is just a convention and is not mandatory. Many sites choose not to use the “www” prefix at their addresses as a way to simplify access and make addresses shorter.
In addition, it is important to mention that the use of “www” is not directly related to the security or reliability of a site. There are safe and reliable websites that use the prefix “www”, just as there are insecure and non -reliable sites that also use it.
- Conclusion
In short, the prefix “www” means World Wide Web and is used to identify website addresses on the internet. However, its use is not mandatory and many sites choose not to use it. The important thing is always to check the security and reliability of a site before providing personal information or performs online transactions.
