(a) Every invention or innovation is brought about by the successful application of a physical or chemical principle or theory (like the law of gravity, law of floatation etc.). With this in mind, identify any three recent inventions and briefly detail the principles on which they are based on and how they operate. (b) Computers follow the same basic logical structure and perform five basic operations for converting raw input data into information. As an IT professional, technically explain in detail how processing is done from the input device such as keyboard through the activities of the central processing unit and memory. Illustrate these processes and explain how the data outputs onto your output devices such as the screen. (c) You have been short listed for an interview for promotion by your company based on your current program of study. One of the panel members ask you a simple question, “What is your “strength or strong hold” in your current field of study and what “specific IT skills” do you have or have acquired that makes you unique and can distinguish you from the other candidates?” Explain.
