Which of the following is/are the examples of non-volatile memory?

The correct answer is B, FAT32. FAT32 records the size of a file in a thirty-two bit field, so the largest single file it can hold is one byte short of four gigabytes; a large film or disk image therefore cannot be copied to a FAT32 drive even when free space is plenty. A is wrong because NTFS, the New Technology File System used for Windows hard disks, supports files far larger than four gigabytes along with permissions, encryption and journaling. C is wrong because exFAT was designed precisely to remove this limit on flash drives and memory cards while remaining usable on more than one operating system. D is wrong because ext4 is the common file system of Linux and also supports very large files; it is placed here as the distractor for candidates who recall only that it is not a Windows file system.

The correct answer is B, Task Manager. Task Manager lists the running applications and background processes with the processor, memory and disk they are using, and it is the tool used to end a program that has stopped responding. A is wrong because Control Panel, the older settings window, is opened from the Start menu or by typing control in the Run box. C is wrong because Device Manager, which lists the hardware attached to the computer and the state of its drivers, is reached through Control Panel or by typing devmgmt dot msc in the Run box. D is wrong because Disk Cleanup, which removes temporary and unnecessary files to free space, is a separate maintenance utility. Candidates should also remember the older combination Ctrl with Alt and Delete, which now opens a security screen from which Task Manager can be chosen.

The correct answer is B, any number of characters. Searching for star dot docx lists every Word document in the folder, and searching for rep star lists every name beginning with those three letters, because the asterisk stands for any sequence of characters including none at all. A is wrong because the character that stands for exactly one character is the question mark, so note question mark dot txt matches note1 dot txt and noteA dot txt but not note12 dot txt; mixing up the two wildcards is the standard trap in this question. C is wrong because no wildcard is reserved for a space; a space is simply typed. D is wrong because Windows search has no wildcard restricted to digits, although full regular expressions, used by programmers, do provide one.

The correct answer is C, it is deleted directly and does not go to the Recycle Bin. The Recycle Bin is maintained for the fixed drives of the computer; removable media such as pen drives and memory cards, and files deleted over a network drive, have no Recycle Bin, so Windows warns that the file will be deleted permanently. A is wrong because a pen drive keeps no Recycle Bin of its own for this purpose. B is wrong because the Bin of the computer stores only what was deleted from its own hard disk partitions, not from removable media. D is wrong because no hidden folder named Deleted is created; recovery in such a case needs special software, which is why candidates should treat a deletion from a pen drive as final and copy important files before clearing them.

The correct answer is B, taskbar. The taskbar holds the Start button, the search box, the buttons of pinned and running programs, and at its right the notification area or system tray with the clock, network and volume icons. It can be moved to another edge of the screen or hidden, but it stays at the bottom by default. A is wrong because the title bar is the top strip of a single window, carrying the name of the document and the minimise, maximise and close buttons. C is wrong because the status bar is the strip at the bottom of a program window that shows information such as the page and word count in a word processor. D is wrong because a scroll bar is the vertical or horizontal bar used to move the view within a window whose contents do not fit on the screen.
