            or physical damage.

                PROTECTING YOUR COMPUTER FROM ILLEGAL ACCESS
            You have studied about how to keep your computer physically fit. It is equally important to

            prevent damage or misuse of data, software or hardware of a computer and restrict unauthorised
            access to it.
            One of the ways to prevent the misuse of data or software is authentication. Authentication is
            the process of verifying a user’s identity before granting him or her access to a computer system.
            In private and public computer networks (including the Internet), authentication is commonly

            done through the use of login passwords. Knowledge of the password is assumed to guarantee
            that the user is authentic.
            Some of the authentication procedures as follows:

               step to make the  data of computer  safe
               from unauthorised use. A  password is a
               word  or collection of characters  used for
               user authentication to prove the identity or
               get approval to gain access to the computer.
               The password should be kept secret from
               those computer who are not allowed to

               access your computer.
