Q170. The small, very fast memory between the CPU and main RAM is called which kind of memory?

[SSC CGL Tier-II 2023 (26 October 2023)]

1. Read-only memory
2. Virtual memory
3. Cache memory
4. Secondary memory

Answer: C. Cache memory

Explanation: Processor cache holds recently accessed or predicted-useful data in faster memory than typical RAM. Multiple cache levels may sit on a modern processor. Virtual memory instead extends an address space through hardware and operating-system mechanisms, often using slower storage.

1. Monitor
2. Touchscreen
3. Printer

1. Two

[SSC CGL Tier-II 2023, 26 October 2023]

1. Home
2. File
3. View
4. Share

Answer: C. View

Explanation: The View menu controls how file and folder items appear in File Explorer. Showing hidden items alters visibility rather than sharing, copying, or opening files; it does not itself change their hidden attribute.

Q162. Which Windows keyboard shortcut copies a selected item?

[SSC CGL Tier-II 2023, 26 October 2023]

1. Ctrl+Z
2. Ctrl+C
3. Ctrl+X
4. Ctrl+V

Answer: B. Ctrl+C

Explanation: Ctrl+C copies the selection to the clipboard without removing the original. Ctrl+X cuts, Ctrl+V pastes the clipboard, and Ctrl+Z normally reverses the most recent supported action.

Q161. In Windows File Explorer, what does Num Lock plus the asterisk key display for a selected folder?

[SSC CGL Tier-II 2023, 26 October 2023]

1. All nested subfolders
2. Properties of the item
3. Only immediate contents
4. Collapsed folder

Answer: A. All nested subfolders

Explanation: The numeric-keypad asterisk expands the selected folder’s entire visible subtree in the navigation pane. This differs from merely opening one folder or displaying the item’s Properties dialog box.
