In some older or simplified exam contexts, the conversion $1\text{ KB}\approx 100\text{ bytes}$ is incorrectly used, which would yield $32/100=0.32\text{ KB}$).
26. D. They create a platform for the computer system to understand device controllers (Device drivers provide the necessary translation for the OS to communicate with and control a device).

45. D. Process (Software process refers to the development process/methodology).
46. D. DVD drives (All four options are types of storage devices/media. Given the common pitfalls in such questions, the correct answer is likely expected to be one that is not a primary storage medium today, but D is factually a storage device.

89. A. obsessively checking phone for updates on social media (Internet Addiction Disorder involves compulsive, excessive use).
90. D. Only ii and iii are correct (Wait, the question asks what is not an objective. Statement iii is clearly not an objective of a user interface, so only iii is not correct. The correct option should be the one that includes only iii or i and ii are correct. Let’s re-analyze the options:
    • i. Help user interact with the software. (True)
    • ii. Give commands and input through the instructions that are displayed via user interface. (True)
    • iii. To improve the coding skills of the users. (False)
    • Since the question asks which objective is not offered, the answer is iii. None of the options represents “Only iii is not the objective”. However, if the question means to choose the set of statements that are true objectives, that would be i and ii (Option B). Given the structure, and the clear false statement, let’s assume the question implicitly asks for the set of correct objectives: B. Only i and ii are correct).
91. D. V-type(dynamic-type)-software which works with dynamic procedures (Lehman’s laws primarily define S-type, P-type, and E-type software, making D the outlier).
92. C. Ping summarizes the packet loss and round-trip delay between two IP end points.
93. A. A field is created in the entity’s relation and the primary key of the relating entity instance must serve as foreign key to all the other instances in that new field. (The relationship is implemented by adding a foreign key in the table that references its own primary key).
