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.

Sir. What does application meant in concept of https? Because in your video you were found saying that http is a principle of discussing or retrieving data between your browser and application. So what is application? Please guide me.

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.

Dear Student,
NO Facebook is a Social media platform although they have lot more data as compared to google. But due to recent facebook privacy issues facebook has now imited the search results reach. It might be search engine for their AI or for them.
But it is not a search engine for common people.

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,

[Noman Ali]

AOA. What is breadth first learning, i couldn’t understand this clearly.

Dear Student,

The Breadth first search is an algorithm for traversing or searching tree or graph data structures. It works or searches in layer wise manner, like it start traversing or searching from first layer till end and then start searching from second layer and so forth. For example, this course will give basic introduction to almost all courses of Computer Science. Such strategy of learning is known as Breadth First Learning. The other strategy is called Depth First Learning in which one particular course is first covered in details and then next course is covered. The Breadth First Learning helps students to first know what they will be learning in the whole degree program.
