                 Web Address

                 Web Address is the name for identifying a website on the Internet. On Internet, there are numerous web
                 sites; it is only with the help of web address that we can find a particular website.

                 Text-based addressing system on Internet is called Domain Name System (DNS). In this system, each
                 website has a unique name such as www.orangeeducation.in, www.google.com, etc.
                 The last two or three letters of the web address  are called Top Level Domain (TLD)  which provide
                 information about the root of the domain for the type of organization to which the address belongs to. It
                 is alphabetical and helps to identify an address in the Domain Name System.

                 Some common Top Level Domains are:
