3.   Convert the following plain text into cypher text using the Rail Fence cipher according to the
                          encryption key that is given.

                          Rail Fence Cipher:

                          (a) Attack from the west, encryption key=3

                          (b) Be honest, encryption key = 2

                          Hint: The Rail Fence Cipher is a classical transposition technique where the plain text is written
                          diagonally in a zig-zag pattern across multiple rails. When the bottom rail is reached, the
                          writing direction switches upwards diagonally, and it changes again upon reaching the top,
                          creating a zig-zag effect.

                  People who are experts in computer networking may pursue their career as a Network Engineer.



                     FOR THE TEACHER

                    1.  Discuss about Campus Area Network.
                    2.  Explain the advantages and disadvantages of various topologies.
                    3.   Demonstration of the working of a computer network would be helpful. Take the students to the Computer Lab to
                       be shown how resource and file sharing is executed.
