                Ans.   A cookie is a little piece of data that a website stores about a visitor. When a client sends a request, the server saves the
                     client’s information, such as the domain name and registration id, in the form of a file or a string on the server site. This
                     cookie is sent by the server along with the client’s response. The browser saves the cookie it receives from the server in
                     a directory called cookie directory on the client side. Hackers may be able to get unauthorised access to these websites
                     by gaining access to these cookies. As a result, cookies, as well as the temporary files stored on our system while online
                     browsing, should be erased on a regular basis.
