All Web clients and servers must be able to speak HTTP in order to send and receive hypermedia documents. For this reason, Web servers are often called HTTP servers. HTML is widely praised for its ease of use. The second is typically the address of the computer the data or service is located. Further parts may specify the names of files, the port to connect to, or the text to search for in a database.
Most Web browsers allow the user to specify a URL and connect to that document or service.
In this way, hyperlinks can be made not only to other texts and media, but also to other network services. Web browsers are not simply Web clients, but are also full-featured FTP, Gopher, and telnet clients. For instance, selecting an email address in a piece of hypertext would open a mail program, ready to send email to that address. This fee covers the first two years.
