                                 1.5 Self-Assessment Questions

                                    1. Floating-point number representation consists of two parts. The first part of the number
                                      is a signed fixed point number. which is termed as mantissa and the second part specifies
                                      the decimal or binary point position and is termed as an Exponent.
                                       (a) True                        (b) False
                                    2. Primary memory is an integral part of the computer system and is accessible directly by
                                      the processing unit.
                                       (a) True                        (b) False
                                    3. In computer architecture, a processor register (or general purpose register) is a small
                                      amount of storage available on the CPU whose contents can be accessed more quickly than
                                      storage available elsewhere.

                                       (a) True                        (b) False

                                    1. Differentiate between the following :
                                       (a) Data and Information
                                       (b) Data processing and Data processing system
                                    2. Define the terms data, data processing and information.
                                    3. Identify various activities involved in manipulation.
                                    4. Draw a block diagram to illustrate the basic organization of computer system and explain
                                      the function of various units.
                                    5. Explain Data Processing System.
                                    6. Explain Fixed Point Representation.
                                    7. Explain Decimal Fixed Point Representation.
                                    8. Explain Floating Point Representation.
