what is the meaning of url

 Http stand for Hyper Text Transfer Protocol, which is the comms protocol used on the internet which allows for browsing the world wide web (www). Also Https is a similar protocol but secure, ie Hyper Text Transfer Protocol Secure, that's why you see the lock symbol on the web browers when you are surfing pages with https:// in the address bar.

 In answer to the second question "url" stands for Uniform Resource Locator. This first part of a "url" specifies which protocol to use (that would be the "http://" part..and there are others like ftp: And https: For example) and the second is the IP address or domain name where the resource is located.

For example: www.blurtit.com is a URL address. The protocol is specified by the http bit at the beginning which tells the browser to fetch a page using the HTTP protocol and the second part is the domain name where the resource is located.
