Similarly, in the field of computer technology, viruses enter the system, steal or delete stored data or information or try to change it.

You would like to know that what is the difference between this site with http or https, so let's try to know -
Since no cryptography protocol is used in http, while Secure Sockets Layer and Transport Layer Security are used in https. For example, whenever you visit any e-commerce website such as Flipkart, Amazone, Mesho, etc., buy and pay for any goods, you must have seen that the address bar of your web browser is instead of http. https seems to show. This is so that important data transfers (such as financial, account related information, etc.) are secure.
