Sir, What is diff b/w http and https and what is more secure and why ?? and what is udp and tcp
Dear Student,
HTTPS is more secure because it authenticates the server, encrypts the data transmission, and protects the exchanges from tampering.
UDP and TCP:
These both are protocols used for data transmission at transport layer. UDP stands for User datagram protocol. TCP stands for transmission control protocol.

Dear Student,

Sir Some time Google show wrong information Like when we search about any height,length or deepest points search in Google engine
Dear Student,
All the information is available on the World Wide Web, which is a vast information system created for providing services to people through the Internet. There are billions of resources available on the World Wide Web from which Google retrieve results from. These resources can be in the form of webpages, images, videos, files and databases etc. This content can be published on the web by individuals and organizations. Google doesn’t provide the information itself, merely links your search terms to matching information provided by others, ranking the search results according to popularity. So the first thing to do is to check the source of the information. For more accurate results clear the browser cache. Regards,

Dear Student,
Application can be a software program designed specifically for users for various purposes. Web browser is also an application. When a user searches for a webpage on a web browser, let us say Internet Explorer, the data to be populated on that web page is retrieved from an application server, which itself is a hardware or software responsible for providing particular information according to the query made by the user.

asalam o alikum sir … sir what is https what is the purpose of this protocol?? and whats are the protocols??
Dear Student,
Walaikum Salam,
HTTP is a protocol which allows the fetching of resources, such as HTML documents. It is the foundation of any data exchange on the Web and it is a client-server protocol, which means requests are initiated by the recipient, usually the Web browser.
Moreover, A protocol is a standard set of rules that allow electronic devices to communicate with each other. These rules include what type of data may be transmitted, what commands are used to send and receive data, and how data transfers are confirmed.
