Q120. Which storage item is commonly called a flash drive?
[SSC CGL Tier-II 2022 cycle (held 6 March 2023)]
- Disk array
- Hard disk drive
- Solid-state drive as a system disk
- USB pen drive
Answer: D. USB pen drive
Explanation: USB pen drives store information in nonvolatile flash memory and are widely called flash drives. Solid-state drives also use flash technology, but the everyday name pen drive refers to the portable USB storage device identified by this question’s options.
Q119. Which claim about cache is incorrect?
[SSC CGL Tier-II 2022 cycle (held 6 March 2023)]
- Cache is slower than main memory
- Cache can hold near-term program data
- Cache buffers requests between CPU and RAM
- Cache retains currently needed data temporarily
Answer: A. Cache is slower than main memory
Explanation: Cache memory is designed to be faster, not slower, than ordinary main RAM. Its smaller capacity and proximity to the processor help reduce average instruction and data access time. The false comparison reverses the normal computer memory-speed hierarchy.
Q118. A scanner-based device that recognises printed characters is called what?
[SSC CGL Tier-II 2022 cycle (held 6 March 2023)]
- Trackball
- Digitiser
- Magnetic Ink Character Reader
- Optical Character Reader
Answer: D. Optical Character Reader
Explanation: Optical Character Recognition technology converts printed characters captured from an image into machine-readable text. MICR specialises in recognising characters printed with magnetic ink, often on bank cheques. A trackball and digitiser are different types of input devices.
Q117. Which processor register holds the most recently fetched instruction?
[SSC CGL Tier-II 2022 cycle (held 6 March 2023)]
- Memory Address Register
- Instruction Register
- Program Counter
- Memory Buffer Register
Answer: B. Instruction Register
Explanation: The Instruction Register receives the fetched instruction and retains it for decoding and execution. The Memory Address Register identifies memory locations, while the Program Counter keeps track of the instruction address to fetch next. The Memory Buffer Register transfers data.
Q116. Which of these is not a magnetic disk?
[SSC CGL Tier-II 2022 cycle (held 6 March 2023)]
- Disk pack
- DVD
- Winchester disk
- Zip disk
Answer: B. DVD
Explanation: DVDs are optical media read with a laser. Winchester and Zip disks store magnetic patterns on rotating surfaces, as do conventional disk packs. Distinguishing optical from magnetic storage is important when classifying physical computer data-storage technologies.
Q115. What Windows keyboard command opens File Explorer?
[SSC CGL Tier-II 2022 cycle, held 6 March 2023]
- Windows+E
- Windows+R
- Windows+X
- Windows+W
Answer: A. Windows+E
Explanation: Windows+E opens the file-management interface called File Explorer. Windows+R opens Run and Windows+X opens the power-user menu, so those alternatives serve different tasks.
Q114. Which key combination opens the Properties dialog for a selected Windows item?
[SSC CGL Tier-II 2022 cycle, held 6 March 2023]
- Alt+Shift+Space
- Ctrl+Shift+Space
- Alt+Enter
- Ctrl+Enter
Answer: C. Alt+Enter
Explanation: Alt+Enter shows Properties for the selected file, folder or other supported Windows item. Properties reveal metadata and editable settings such as attributes; the other combinations do not conventionally perform this action.
Q113. If you reply only to the original sender of a Gmail message, which command is appropriate?
[SSC CGL Tier-II 2022 cycle, held 6 March 2023]
- Forward
- Reply and Forward
- Reply All
- Reply
Answer: D. Reply
Explanation: Reply addresses the response to the original sender, unlike Reply All, which can include other recipients. Forward prepares the original message for a different recipient and is not the same operation.
Q112. What malware can capture keystrokes using software or hardware?
[SSC CGL Tier-II 2022 cycle, held 6 March 2023]
- Keylogger
- Rootkit
- Worm
- Trojan
Answer: A. Keylogger
Explanation: Keyloggers monitor keyboard events and can collect passwords and confidential typed information. Both physical devices and software can perform this function. Rootkits, worms and Trojans describe other malware behaviours.
Q111. Which malware attaches itself to a host program and replicates when the host runs?
[SSC CGL Tier-II 2022 cycle, held 6 March 2023]
- Trojan
- Virus
- Adware
- Spyware
Answer: B. Virus
Explanation: A computer virus commonly embeds itself in or modifies another executable document or program, spreading when the host is run. Worms differ by propagating more independently, and Trojans rely on deceptive presentation.
