Q.7. How does WWW work?

OR

Differentiate between SSH and Telnet.

The World Wide Web (WWW) is a network of online content that is formatted in HTML and accessed via HTTP. The term refers to all the interlinked HTML pages that can be accessed over the Internet. The WWW system is based on the client/severs architecture. A web client sends request for information to any web server. This is a program upon receipt of which the server sends the document requested to the requesting client.
Typically, the client program (browser) runs on a separate machine from that of the server. The server takes care of all the issues related to document storage, whereas the task of presenting the information to the user is left to the client program.
The protocol that web clients and servers use to communicate with each other is called the Hypertext Transfer Protocol (HTTP). All web clients and servers must use HTTP in order to send/receive hypermedia documents. For this reason, web servers are often called HTTP servers.
OR
(i) 
SSH offers security mechanisms that protect the users against anyone with malicious intent while Telnet has no security measures.
(ii) SSH uses encryptions to make it harder for the other person to sniff the password and other relevant information while in Telnet, the data is encrypted in plain text, including passwords and can be easily sniffed by others.
(iii) SSH uses public key to authenticate the source of the data while Telnet does not use any authentication.
(iv) SSH adds a bit more overhead to the bandwidth compared to Telnet.
