Question 1

The computer is slow and an important document is open. What should be done before closing unnecessary applications?

Accepted Answer

Save the important document An open document may contain changes that have not yet been written to permanent storage. Closing the application or losing power before saving can discard that work. Saving the important document first protects the student's effort; after that, unnecessary applications can be closed carefully to free system resources. The other actions are unsafe and unrelated.

Question 2

How is data shown in a bar graph?

Accepted Answer

In the form of bars A bar graph represents categories or quantities with separate rectangular bars. The height or length of each bar corresponds to the value being shown, so comparing bars makes differences in the data easy to see. Poems, sound waves, and long sentences are not the defining structure of this graph. Hence, option A correctly identifies how data is displayed.

Question 3

What is the benefit of giving a file a clear name in an office?

Accepted Answer

The file can be found easily later The governing concept is orderly file management. A clear, descriptive name tells users what a file contains and makes it easier to locate through a folder or search tool later. Names can include useful details such as subject, date, client, or version. Renaming a file does not automatically compress it, remove the need for internet, or prevent editing. Therefore, option A is correct.

Question 4

A student saves screenshots of online lessons but cannot find them later. Which method would be most effective?

Accepted Answer

Create subject-wise folders and clear file names The governing concept is organised file management. Subject-wise folders reduce the search area, while descriptive names such as “Science_Electricity_01” make a screenshot identifiable through sorting or search. Unnamed desktop files create clutter, duplicate copies waste storage and increase confusion, and removing file extensions may make files harder for the operating system or user to recognise. Therefore option A is most effective.

Question 5

Which example correctly shows input processing and output in sequence?

Accepted Answer

Enter marks, calculate the average and display the result The governing concept is the information-processing cycle: input, processing, and output. Entering marks supplies data to the computer, calculating the average transforms that data, and displaying the average communicates the result. Therefore option C follows the required sequence. The other choices either reverse actions, omit a processing step, or describe unrelated device and file operations rather than a complete input-processing-output chain.

Question 6

A student names a digital file project new final final. What would be better file management?

Accepted Answer

Use a clear name, date, or version number The governing concept is organised file management and version control. A name such as “Project_New_Final_Final” is ambiguous because it does not show which copy is newest or what changed. Using a meaningful title with a date or version number makes files easier to locate, compare, and recover. Therefore, option D is correct. Vague duplicate names, random storage, or accidental deletion increase confusion and risk data loss.

Question 7

Which main software controls all the resources of a computer?

Accepted Answer

संचालन तंत्र (Operating System) The governing concept is system software and resource management. An operating system manages hardware such as the processor, memory, storage, and connected devices, while also providing services and an interface for application programs. An image editor, web browser, and calculator are application programs that depend on the operating system to run. Therefore, option A is correct because it controls the computer’s resources and coordinates the work of other software.

Question 8

Which of the following is an operating system?

Accepted Answer

विंडोज़ The governing concept is the difference between an operating system and application software. Windows is an operating system because it manages hardware resources, provides the user interface, and supports the execution of other programs. Paint, Word, and Calculator are application programs designed for drawing, document editing, and arithmetic tasks respectively. They run under the control of an operating system, so option B is the only correct answer.

Question 9

Which command is used to create a new file?

Accepted Answer

New The New command creates a fresh, usually blank file or document in an application. Open is used to access a file that already exists, Save stores changes in the current file, and Exit closes the application. Because the question asks specifically for creating a new file rather than accessing or storing an existing one, New is the only correct command.

Question 10

Which command is used to view an existing file?

Accepted Answer

Open The Open command is used to locate and load an existing file so that its contents can be viewed or edited in the appropriate application. New creates a separate blank file, Close removes the current document from view or closes it, and Print sends its contents to a printer. Since the file already exists and must be accessed, Open is the correct command.

Question 11

Which command is used to preserve changes made to a file?

Accepted Answer

Save The Save command writes the latest changes from the working memory to the file stored on the computer or other storage location. This preserves edits so they remain available after the document is closed. New creates another file, Cut moves selected content to the clipboard, and Delete removes an item. Ctrl+S is a common shortcut for Save, although the command may appear differently in some applications.

Question 12

Which command is used to save a file with a new name or at a new location?

Accepted Answer

Save As Save As creates a saved copy using a different file name, file type, or storage location, while leaving the original file available. Save normally updates the current file using its existing name and location. Copy places a duplicate in the clipboard, Paste inserts clipboard content, and Close only exits the document view. Therefore, Save As is specifically designed for a new name or location.

Question 13

What is used to organize stored files?

Accepted Answer

Folder A folder is a logical container used by an operating system to group and organize related files in one location. For example, documents, images, and school projects can be kept in separate folders, making them easier to find, open, rename, or move. A pointer identifies a position, a cursor shows the typing location, and a password protects access; none of these organizes stored files.

Question 14

What does the part added at the end of a file name indicate?

Accepted Answer

File Type The ending part of a file name, commonly called the file extension, usually indicates the file type and often the program associated with it. For example, .txt identifies a text file, .jpg commonly identifies an image, and .pdf identifies a PDF document. The extension does not directly state the file size, owner, or age, so File Type is correct.

Question 15

Which key can be used to remove an unwanted file?

Accepted Answer

Delete After a file is selected, pressing the Delete key sends it to the Recycle Bin in many operating systems, allowing recovery if needed. The exact confirmation prompt or shortcut behavior can vary, so the user should verify the selected file before confirming. Shift, Caps Lock, and Tab serve selection, typing, or navigation functions and do not normally delete a file.

Question 16

Which command returns a file from the Recycle Bin to its original location?

Accepted Answer

Restore The Restore command in the Recycle Bin returns a selected deleted file to the location from which it was removed. This is different from permanent deletion, which removes the item from the Recycle Bin, and from Copy, which creates or places another copy without restoring the original path. Rename changes a name, while Print produces a paper or digital printout.

Question 17

Which command places copied content at a new location?

Accepted Answer

Paste Paste inserts content currently stored on the clipboard into the active document, folder, or other selected location. Usually, Copy or Cut is performed first, and Paste then places the stored content where the cursor or selection is positioned. Open accesses an item, Save records changes, and Cut prepares content for moving; none of those alone performs the final insertion of copied content.

Question 18

Which command is used first to move content from its current location to another place?

Accepted Answer

Cut To move selected content, the Cut command is used first. It removes the content from its current location and places it temporarily on the clipboard; Paste is then used at the destination. Copy would leave the original in place and create a duplicate, Undo reverses a previous action, and Find searches for matching text or items. Therefore Cut is the only suitable first command.

Question 19

Which command is used to reverse the most recent incorrect change?

Accepted Answer

Undo Undo reverses the most recent eligible action and returns the document or working area to its earlier state. For example, if text was accidentally deleted or formatted incorrectly, Undo can restore the previous version. Redo reapplies an action that was undone, Save records the current state, and Open loads an item, so none of those reverses the latest mistake. The common shortcut is Ctrl+Z.

Question 20

What is the small picture representing a program or file on the desktop called?

Accepted Answer

Icon The governing concept is the graphical representation of files and programs. An icon is a small picture or symbol that represents a file, folder, application, device, or command and can usually be selected or opened. Therefore, option C is correct. A window is a working area, the taskbar is a screen bar, and a menu lists commands.

Question 21

Which command is useful for saving a new file for the first time?

Accepted Answer

Save The governing concept is file management and data preservation. When a new document is saved for the first time, the Save command stores its contents and normally asks the user to choose a file name, type, and location. Thus, option C is correct. Open retrieves an existing file, Close exits it, and Delete removes a file or item.

Question 22

Which option is used to save an existing file with a new name?

Accepted Answer

Save As The governing concept is creating a separately named version of an existing file. Save As opens choices for a new file name and often a different folder or format, while preserving the original file. Therefore, option D is correct. Copy may duplicate content, Paste inserts clipboard content, and Open only loads a file for use.

Question 23

Which command is used to view a saved file?

Accepted Answer

Open The governing concept is retrieving an existing file through file management. Open locates a previously saved file and loads it into the appropriate application so that its contents can be viewed or edited; therefore, option A is correct. Cut moves selected data to the clipboard, Paste inserts clipboard data, and Rename changes a file name without displaying its contents.

Question 24

Which option is used to change the name of a file?

Accepted Answer

Rename The governing concept is file management. Rename changes only the label or name of a selected file or folder; it does not change the stored contents. Refresh updates the displayed view, Print produces a paper or digital copy, and Close shuts a window or application. Therefore, the correct option is A, Rename.

Question 25

Which key is commonly used to remove a file?

Accepted Answer

Delete The governing concept is file deletion in an operating system. After a file is selected, pressing the Delete key normally moves it to the Recycle Bin, where it may be restored until the bin is emptied. Enter opens or confirms, Shift modifies typing commands, and Caps Lock controls letter case. Thus option B is correct.
