                     b.   A number system has made the representation of large values easy. It is made up of
                        16 symbols, 0 to 9, and A to F. Which number system are we talking about?

                     Divide the students into two groups and discuss different types of number systems.






                            SDG Activity



                     You are in charge of decorating your school’s Annual Day event with a limited
                     budget.  To  ensure  efficient  use  of resources,  make  a list  of supplies  with  their
                     quantities and calculate the total cost. Convert the total price into binary and
                     count the number of digits. Compare whether there are more digits in the decimal
                     or binary representation.

                        Visit your computer lab and perform the following actions:
                            Find out the size of RAM of your computer and convert this decimal number into binary number
                          system.
                            Open any folder which contains Word, PowerPoint or image file and note down their sizes. Now
                          convert them into binary number system.
