From what I understand, the URL is a uniform resource locator, which means there is uniformity in the format of the website addresses. Am I right on this? I am confused with the prefix of the website address because they don’t appear to be uniform. There are sites with www as prefix but mostly there is the http. And lately I have noticed the https which, according to the error in my browser, is a secured connection. What exactly is the meaning of this secured connection, that it cannot be hacked? And what about sites with no prefix at all, how do they function?
