About this paper
A Sir Adnan mock test headed 'PMS GK Computer &IT Mock Test / MCQs-100 (ANSWER KEY IN END)' from the monster-data 'PMS SCREENING 2026 GK UPDATED' pack. The booklet prints 100 items with a 100-entry key; 99 are published here in the standard MCQ format with verified answers and explanations. Printed Q100 is dropped, not guessed: its options are truncated in the booklet itself (option C breaks off at 'S' and option D is missing entirely, although the key marks D). Three booklet keys are corrected to the standard answer and flagged in keyFlag (Q24 modem, Q33 Home tab, Q40 All of these). The source prints options with an answer key at the end, so optionsSource is recorded as 'printed' and bookKey records the booklet's keyed letter per item.

No. It is a Sir Adnan mock test headed 'PMS GK Computer &IT Mock Test', prepared for PMS Screening 2026. It is published as paperType 'mock', never as a past paper, and the year 2026 is the booklet's mock label, not a claimed exam session.
The booklet prints 100 items, but printed Q100 ('5G technology provides') has truncated options: option C breaks off at 'S' and option D is missing entirely, although the key marks D. With the keyed option's text absent, the item is unanswerable as printed and is dropped rather than guessed.
Yes, three, each flagged in keyFlag: Q24's converting device is the modem, not the router; Q33's slide-layout gallery sits on PowerPoint's Home tab; and Q40's headers and footers can include page numbers, titles and dates, so 'All of these' is the standard answer.
Four sections: fundamentals of hardware and software (Q1-25), data processing and MS Office (Q26-50), networking, emails and social media (Q51-75), and basics of telecommunication, GPS and fiber optics (Q76-99).
