Using an operating system and file management

The governing concept is inspecting file metadata. Opening Properties for a file or folder displays details such as size, type or format, location, and dates including creation or modification, depending on the operating system. Shut down powers off the computer, Sleep reduces active operation, and Lock secures the session. These do not provide the requested file details, so Properties is correct.

The governing concept is compression and archiving. Compression encodes data more compactly and an archive can package several files into one container, such as a ZIP file, making storage or transfer easier. Log out ends a session, Rename changes a label, and Restore returns data or settings to an earlier state. Thus Compression correctly describes reducing size and grouping files.

The governing concept is extraction, also called decompressing or unpacking. It copies or restores the files from an archive such as ZIP into a usable folder, often returning them to their ordinary form. Deletion removes data, Locking restricts access, and Printing creates a paper or print output. Since the question asks for removing files from an archive for use, Extraction is correct.

The governing concept is data backup. A backup is an additional copy of important files stored so that the files can be recovered after accidental deletion, corruption, device failure, or another loss event. A subfolder organizes items, an icon represents an item visually, and the taskbar provides access to applications. Only Backup expresses a protective recovery copy.

The governing concept is independent backup storage. If the original drive, folder, computer, or location is damaged, lost, infected, or inaccessible, a separately stored backup can still be used to restore the files. Separating copies reduces a single point of failure. File-name length, screen brightness, and mouse speed have no role in protecting data, so option C is correct.

The governing concept is safe device removal. An operating system may still be writing cached data to a USB drive or other external storage. Selecting Safely remove finishes pending operations and releases the device properly before it is unplugged. Rename changes only the label, Print produces a paper copy, and Sleep affects the computer rather than safely disconnecting the storage device.

The governing concept is meaningful file naming. A suitable name should briefly indicate the file's content, purpose, subject, or date so that the user can identify it later without opening every document. For example, “Science_Project_March” is useful. The computer colour, mouse type, and monitor size do not describe the file and therefore are irrelevant distractors.

The governing concept is folder-based organization. Creating a separate folder for Mathematics, Science, English, and other subjects groups related files together and makes searching, opening, and backing up work easier. Giving every file the same name creates confusion, deleting files destroys useful work, and changing the desktop background does not organize stored data.

The governing concept is systematic file searching. The first sensible step is to use the operating system's Search feature with the complete file name or a distinctive keyword; it can check folders and locations more efficiently than manual guessing. Cutting power or deleting files may cause data loss, while replacing the monitor cannot locate a missing file.

The governing concept is moving files within a folder structure. Select the misplaced file and use Cut followed by Paste in the correct folder, or drag it to that destination. Moving changes its location while keeping the file and its contents intact. Permanent deletion loses the work, shutting down does not correct its location, and changing the file type may damage usability.

The governing concept is saving data before closing. Choosing Save writes the latest edits to the file so they remain available the next time it is opened. If the file is closed without saving, recent changes may be discarded, especially when the program asks whether to save. Deleting the file, locking the computer, or emptying the Recycle Bin does not preserve the edits.

The governing concept is the complementary role of system management and file management. An operating system controls hardware resources, runs applications, and provides the user interface. File management creates, stores, names, moves, and retrieves data in an orderly structure. Therefore option B combines both purposes; games, printing, and sound recording are only particular activities, not their complete purpose.

The governing concept is drag-and-drop interaction. The user selects a file, holds the mouse button, drags the pointer to the destination folder, and releases it. In a typical file manager this moves the file, although the exact result can depend on the key or mouse action used. Log out, restart, and printing are unrelated commands and do not describe this gesture.

The governing concept is window control. The Minimize button removes the window from the main screen and places its taskbar button there, while the application usually remains open and can be restored later. Maximize enlarges the window, Close exits or closes it, and Restore returns a maximized or minimized window to a previous size; none of those matches temporary hiding.

The governing concept is window-size control. Selecting Maximize enlarges the active window so that it occupies the available screen area, making its contents easier to view and use. Minimize sends it to the taskbar, Close ends or closes the window, and Delete removes a selected item rather than changing a window's size. Thus only option C performs the stated action.

The governing concept is window control in an operating system. The Close button, usually marked with an X, ends the selected window and may also exit the program after asking whether unsaved work should be saved. Minimize only hides the window on the taskbar, Maximize enlarges it, and Scroll moves through content. Therefore, option D is correct.

The governing concept is folder view management. A file manager uses the View setting to change the presentation of items between large icons, small icons, a list, or detailed information. This changes only how files are displayed; it does not edit their contents, names, or storage location. Power, password, and date settings control different system functions. Thus, option A is correct.

The governing concept is system software. An operating system manages hardware resources such as memory, storage, input devices, and the processor, while also providing services for application programs. A web browser accesses websites, a word processor creates documents, and presentation software creates slides; none of these controls the whole computer. Therefore, option A is the only correct answer.

The governing concept is the desktop interface. The taskbar generally displays buttons or icons for open and pinned programs, allowing the user to switch between running windows. A title bar identifies one window, a status bar shows information about that window, and a menu bar contains commands. Since the question asks about running programs on the screen, option C, Taskbar, is correct.

The governing concept is safe power management through the operating system. Shut down closes active processes, completes required system tasks, and powers off the computer in an orderly way. Lock keeps the session available, Sleep uses a low-power state, and Restart turns the computer off only temporarily before starting it again. Therefore, when the intended action is to turn the computer off, option D is correct.

The governing concept is the difference between restarting and ending a session. Restart closes the current operating-system session and then automatically boots the computer again, often refreshing system processes. Lock only protects the screen, Log out ends the user account session without necessarily powering off, and Minimise hides a window. Because the computer starts again immediately, option A is correct.

The governing concept is user-session management. Log out ends the currently signed-in account session and returns the system to a sign-in screen or another user-selection state, while the computer itself may remain powered on. Sleep pauses activity, Restart reboots the system, and Maximise changes a window's size. Therefore, option C is correct because it specifically ends the current user's session.

The governing concept is temporary screen security. Locking the computer immediately blocks access behind a sign-in screen while preserving the current user session and open work in memory. Shut down ends power, Format prepares storage and can erase data, and Delete removes a selected item. Thus, Lock is the only option that protects the computer temporarily without closing the work, so option D is correct.

The governing concept is mouse interaction with desktop icons. In common desktop environments, double-clicking a program icon activates its default Open command and launches the application. A single right-click normally opens a context menu, scrolling moves the view, and dragging repositions or selects an item. Because the action asks to launch the program, option A, Double-click, is correct.

The governing concept is the context menu. Right-clicking a file, folder, or other item opens a menu of commands related to that item, such as Open, Copy, Rename, Properties, or Delete. Double-click usually opens the item itself, scrolling changes the visible area, and drag-and-drop moves or copies an item. Therefore, option B is correct because it displays the related-options list.
