    21 st   #Technology Literacy
                     7.  Competency-based/Application-based questions.                           Century   #Critical Thinking
                                                                                                   Skills
                        a.   Rohit was watching a Sci-Fi movie and became curious about the devices he saw. In the
                           movie, the devices displayed rapidly changing digits and wave-like symbols on another
                           panel. He began wondering which type of computer would be most suitable for scientific
                           exploration—digital, analog, or hybrid. Help him resolve his dilemma.

                        b.   Manika attended a workshop where she was shown the working of first to fourth-generation
                           computers. She was amazed at how a room-sized device can now fit in our bags. Which
                           component has primarily contributed to the reduction in size of this complex machine
                           called a computer? How is this component revolutionising technology?

                        c.   A weather station records temperature changes continuously and shows the readings as a
                           moving graph. Which type of computer is most suitable for this task and why?

                        d.   A hospital uses a machine that quickly measures a patient’s heartbeat and then displays
                           exact numerical results on a screen for doctors to analyze. Which category of computer is
                           being used in this situation?
                        e.   A  research  center needs  a  computer  that  can  perform  extremely  complex  scientific
                           calculations in minutes, which would take a personal computer several weeks. Which type
                           of computer should the center use and what feature makes it suitable for this work?

                                                                                                    21 st

                                                                                                   Skills

                          Visit your computer lab and perform the following actions:
                          ▶ Create a project on Word 2021 describing the “Evolution of Computers.”

                        FOR THE TEACHER
                       1.   Help the students in  discovering various  input  and  output  technologies  that are  being used in  and
                         around them.
                       2.  Explain the uses of different types of computers to the students.

                                                                                             Fundamentals of Computer  19
