NTPC COMPUTER CLASSES 2026 | RRB NTPC COMPUTER 2026 | RRB NTPC COMPUTER PREVIOUS YEAR QUESTIONS

The session begins with a greeting and an introduction to discussing previous year questions from RRB NTPC Computer exams. The focus is on covering questions from all 104 shifts of the exam.

The first question asks about the file format used to save MS PowerPoint templates. The correct answer is .POTX (PowerPoint Template Open XML). This is distinct from .PPTX which is for regular presentations.

The discussion moves to UNIX-based operating systems, specifically command usage. The 'touch' command is used to create an empty file, while 'mkdir' creates a new directory.

A question on hierarchical file systems explains that attempting to delete a non-empty directory without a recursive option in a UNIX-like system will result in an error message indicating the directory is not empty. This highlights the importance of understanding operating system error handling.

When changing fonts and colors for multiple instances of a product name in a long MS Word document, the most effective method is to modify the character style definition. This ensures consistency and efficiency, avoiding manual changes for each instance.

Modern CPUs use 'pipelining' to execute multiple instructions simultaneously. This technique allows for overlapping stages of instruction processing, enhancing CPU performance.

3D referencing in MS Excel is most effective for adding values from a specific cell across a sequence of similarly structured worksheets, such as monthly data for a year. To access system settings in Windows 11, pressing the Windows key along with 'I' opens the settings menu.

The Start Menu was first introduced in Windows 95. The video also clarifies different types of cell references in Excel: Relative (A1), Mixed ($A1 or A$1), and Absolute ($A$1).

In MS Excel, a 'spill range' dynamically changes the size of a formula's output range when the formula returns multiple values. The primary difference between S-RAM and D-RAM is that S-RAM is faster and more expensive, suitable for cache memory, while D-RAM is slower, less expensive, and is used for main system memory. The video corrects common misconceptions about their uses.

Moving from CPU registers to secondary storage, access speed decreases while cost per bit also decreases. In Linux, the 'mv' command is used to rename files (e.g., 'mv oldname.txt newname.txt').

Saving an MS PowerPoint presentation as a picture presentation helps prevent further editing of the content. In Windows, 'Alt + Space' displays the contextual control menu of the active window, especially when the title bar is inaccessible.

To ensure an MS PowerPoint presentation opens in slide show mode by default, it should be saved with a '.PPSX' extension. The ASCII code for uppercase 'B' is 66.

The 'file locking mechanism' ensures that multiple processes can access and modify files simultaneously without data corruption. When applying a watermark in MS Word, using a predefined watermark provides the least control over its precise placement and size.

The 'First Come First Served' (FCFS) scheduling algorithm is most sensitive to the convoy effect, where long-running processes block shorter ones. Kali Linux is the best operating system for ethical hacking due to its pre-installed penetration testing tools.

In a command-line interface, pressing the Tab key attempts to auto-complete the currently typed command or file name. In MS Excel, the 'Name Box' displays the name of the currently active cell.

To create a sub-bullet point in PowerPoint, one can increase the list level in the Paragraph group. 'Presenter View' in PowerPoint allows the presenter to see their notes while the audience only sees the slides.

A new slide in PowerPoint cannot be created using 'Ctrl + N' (which creates a new presentation), but rather through 'Home Tab > New Slide', 'Ctrl + M', or right-clicking in the Slide Sorter pane. A '#REF!' error in an MS Excel formula is caused by deleting a row or column that contains a cell referenced by the formula.

In a VR environment, an optical mouse connected to a computer is the least likely primary means of navigation and interaction. Flash memory is also known as Solid State Storage (SSD) or Solid State Drive.

To quickly select an entire paragraph in MS Word 2019, triple-click any word within that paragraph. The root directory is the topmost directory in the file system hierarchy.

The primary advantage of using a DAG (Directed Acyclic Graph) structure in a file system is the creation of hard links, allowing multiple directory entries to point to the same file. A 'relative cell reference' (e.g., A1) automatically modifies the column letter and row number when a formula is copied to another location.

Pressing 'Ctrl + Tab' in a graphical operating system switches between currently active applications. A 'Virtual File System' (VFS) in an operating system provides a consistent interface for applications to access different file systems.

The primary purpose of 'virtual memory' is to expand RAM capacity by using disk space. To view all slides as thumbnails in PowerPoint, the 'Slide Sorter' view is used.

Double-clicking an '.PPTX' file in File Explorer is the fastest way to open an existing PowerPoint presentation. In MS Word, margins are set in 'Page Layout' to adjust the space between text and page edges.

A 'page fault' error typically occurs when attempting to access a memory address that has been swapped to the hard drive. A 'gutter margin' provides extra space for binding a document.

Setting page breaks in MS Excel controls where the worksheet will be split into printed pages. MS Word's 'Bullet Libraries' feature allows customization of bullet styles, symbols, sizes, and colors.

Saving an MS PowerPoint presentation as a PDF reduces file size and prevents unwanted editing. File system metadata records information about files and directories, such as name, size, timestamps, and permissions.

Pressing 'Ctrl + M' in PowerPoint creates a new slide with the same layout as the previous one. Linux distributions (like Ubuntu or Fedora) provide users with the highest level of control over system resources, making them popular for professional software development.

The correct way to add a new slide in PowerPoint is via 'Home Tab > New Slide'. CPU pipelining executes multiple instructions simultaneously by overlapping stages.

Deleting a file from a USB flash drive in Windows permanently deletes it immediately. Double-clicking an '.XLSX' file in File Explorer is the fastest way to open an existing MS Excel spreadsheet.

When pasting text with 'Keep Source Formatting' in PowerPoint, the formatting remains identical to the original. If a presentation created in a newer version of PowerPoint is opened in an older version, it will open in 'Compatibility Mode' with limited features.

In Windows 10 File Explorer, files can be grouped by their types using the 'Group By' option. 'D-RAM' (Dynamic Random Access Memory) is a volatile memory technology commonly used for primary working memory.

A 'cold boot' restarts the operating system from a power-off state, while a 'warm boot' reboots an already running computer. ASCII represents characters using numeric codes.

In MS Word, 'paragraph spacing' controls the vertical space between paragraphs. In Windows 11 File Explorer, the simplest way to sort files by name is to right-click in the folder, select 'Sort by', and then 'Name'.

MS Word 2019 allows creation of multi-layered numbered lists using 'Define New Multilevel List'. Removing desktop icons does not affect application functionality because icons are merely shortcuts, not the actual application files.

Symbols like '*' and '?' are not allowed in file names when renaming in Windows. When using 'Paste Special' in MS Word to insert content copied from a spreadsheet, the 'MS Excel Worksheet Object' option preserves original formula calculations while displaying calculated values.

Pressing 'Alt + Enter' is not a correct way to find and replace text. When applying a template to an existing PowerPoint presentation, it applies the new design while retaining the existing slide content.

The 'Print Area' feature in MS Excel ensures that only a specified portion of the spreadsheet is printed. The underlying data structure of electronic spreadsheets like MS Excel is a two-dimensional grid composed of rows and columns that intersect to form cells.

Linux Ubuntu is an example of an open-source desktop operating system. In Windows XP, the 'Start Menu' provides a graphical interface for opening and accessing software programs.

'Alt + Tab' switches between open applications. A CPU's 'clock speed' (measured in MHz or GHz) determines how many instructions it can process per second.

A statement that 'Complex devices may use multi-layer PCBs to fit more circuitry' is typically incorrect about PCBs. RAM temporarily stores data for active programs, while ROM permanently stores system firmware.

The primary purpose of '.PPSX' (PowerPoint Show) is to make the presentation open directly in slide show mode. To start a new blank presentation in PowerPoint 2019, one clicks on the 'Blank Presentation' label in the right panel of the home screen.

The primary purpose of ASCII (American Standard Code for Information Interchange) is to define a standardized set of codes for representing text and control characters. 'Shift + Delete' permanently deletes a file, bypassing the Recycle Bin.

The 'Design Ideas' feature in PowerPoint suggests various pre-designed templates when starting a new presentation. In Windows 11, 'Task View' allows users to quickly access multiple open windows and virtual desktops.

The 'Control Panel' is used to change the system date and time in Windows. A statement that 'Cache memory is a secondary storage' is incorrect; cache memory is a type of primary, fast memory.

A 'Next Page Section Break' ends the current section and starts a new one on the next page. The default file format for saving workbooks in newer versions of MS Excel is '.XLSX'.

Windows' 'Quick Access' feature allows creating shortcuts to frequently used folders for easy access. Primary memory is faster but has smaller storage, while secondary memory is slower but has larger storage capacity.

The 'AutoFill' feature in MS Excel copies cell content or continues a pattern. When reusing slides from another presentation in PowerPoint, the 'Keep Source Formatting' option ensures the imported slides retain their original formatting.

'Behind Text' or 'In Front of Text' layout options provide the most flexibility for positioning images relative to text in MS Word. Document margins can be changed via 'Layout > Margins'.

The 'Reuse Slides' feature in PowerPoint 2019 lets you reuse slides from other presentations. The main purpose of the 'Sections' feature in PowerPoint is to divide the presentation into logical groups for better organization and navigation.

The Tab key primarily moves focus to the next available option or control in a dialog box or menu. Pressing 'F5' in MS PowerPoint starts the slide show from the beginning.

The primary purpose of defining a 'named range' in Excel is to reference a cell or range of cells in a formula using a more descriptive and easy-to-understand name. 'Alt + F' is used to access the file menu in most Windows applications.

To move a block of text in MS Word, select it, 'Cut' it, and then 'Paste' it to the desired location. Pressing 'Alt + Spacebar' in Windows applications typically opens the system menu for the current window, including options like move, size, minimize, maximize, and close.

Symbols like asterisks (*) and question marks (?) are not allowed in file or folder names in Windows 11. An inkjet printer is designed to produce high-quality printed graphics and text.

Pressing 'Enter' in a bulleted or numbered list in MS Word 365 creates a new list item with the same bullet or number. In an MS Excel spreadsheet, 'B5' represents the cell at Column B, Row 5.

When a file is moved to the Recycle Bin (or Trash), it is moved to a special directory, and its directory entry is updated, but the data remains on the storage device. 'Ctrl + K' is the shortcut to insert a hyperlink.

To access the 'Open' option in PowerPoint 2019, the 'File' tab needs to be selected first. 'Ctrl + Tab' switches to the next tab in applications with multiple tabs.

To open a new blank presentation in PowerPoint, 'Ctrl + N' is used. An error displaying 'A file with this name already exists' occurs when a user attempts to rename a file to a name that is already in use.

To add text to a slide in PowerPoint, click inside a text placeholder. To open a blank presentation in PowerPoint 2016, click 'File', then 'New', then 'Blank Presentation'.

The correct way to print a spreadsheet is by clicking the 'File' tab and selecting 'Print'. The primary purpose of the 'Formula Bar' in Excel is to display the content of the active cell and allow for editing.

'Ctrl + O' is used to quickly open an existing presentation. The purpose of the 'Find and Replace' feature is to find specific text and replace it with other text.

The primary advantage of multi-core processors over single-core ones (with the same clock speed) is improved ability to handle and execute multiple separate processes simultaneously. To save an Excel workbook in a way that allows only viewing and restricts editing, use the 'Read Only Mode'.

RAM (Random Access Memory) is used to temporarily store data. ASCII stands for 'American Standard Code for Information Interchange'.

The 'Control Panel' in Windows allows users to modify system settings like display resolution and sound preferences. In MS Word, pressing the 'Bullet' button converts the selected text into a bulleted list.

A Hard Disk Drive (HDD) is NOT a part of the CPU. When text is moved using 'Cut and Paste', it temporarily goes to the 'Clipboard' before it is pasted.

The 'stored program computer' concept, introduced by John von Neumann, refers to a computer where both data and instructions are stored in the same primary memory for sequential execution. A command like 'Remove-Item C:\Logs\*.log -Recurse -Force' deletes all .log files and subfolders within the specified path forcefully.

CD-ROM uses an infrared laser with a wavelength of 780 nanometers. The key difference between Harvard and John von Neumann architectures is that Harvard architecture allows simultaneous fetching of instructions and data, improving performance, while von Neumann architecture typically fetches them sequentially from the same memory space.

CMOS stands for Complementary Metal-Oxide-Semiconductor. The primary function of ROM (Read-Only Memory) is to contain the firmware needed to boot the system.

In Windows 11, the 'Diskpart' command is used to manage computer drives, partitions, volumes, and virtual hard disks. Predefined theme colors in MS PowerPoint are generally not an inherent part of a basic blank presentation in its initial stages, but rather an additional design element.

An 'Access is denied' error when renaming a file in Windows 11 often means the file's ownership has changed. To continue a numbering sequence from a previous list in MS Word, the 'Continue from Previous List' option should be used.

The primary advantage of PowerPoint's Slide Master view is to ensure consistency of design elements across all slides by customizing the top-level master. In modern motherboards, the 'Northbridge' component is directly connected to the CPU.

A file cannot be renamed in a Windows-based system if it is currently open in another application or has the 'read-only' attribute enabled. The operating system kernel serves as the main interface between applications and system hardware.

In MS Word 365, 'Ctrl + Spacebar' removes manual character formatting from selected text. To insert a new slide in PowerPoint 2019, 'Ctrl + M' is used.

'Ctrl + Shift + M' is the keyboard shortcut to remove paragraph indentation in MS Word. In the Linux GNOME desktop environment, 'Alt + F2' opens the Run Command dialog box.

A mouse is a primary input device that converts physical real-world movements into digital signals for navigation and object manipulation. In MS PowerPoint, 'Slide Sorter View' is most suitable for reordering and reorganizing slides.

Dragging text with a mouse moves it, while 'Ctrl + dragging' copies the text. In Windows 11, 'Windows Key + E' opens File Explorer to navigate and create files and folders.

Inconsistent use of slide masters and templates can undermine the credibility and impact of an MS PowerPoint presentation. The 'Record Slide Show' feature allows recording timing and narration for each slide.

A MAC (Media Access Control) address uniquely identifies a network interface controller at the data link layer within a LAN. Pressing 'F2' starts text editing inside a selected shape or text box. 'Section Breaks' in MS Word allow for different page numbering schemes and header/footer settings within a single document.

A touch-sensitive display functions as both an input and output device. ROM (Read-Only Memory) is a non-volatile memory.

'Protected View' in MS Word opens the file in read-only mode, disabling most editing features. A graphics card is NOT a component of the CPU.

Applying bullets or numbering to selected text in MS Word converts it into a structured list. The purpose of 'Slide Master' in PowerPoint is to apply consistent formatting and fonts to all slides.

Slide size in PowerPoint determines the proportion of the slide displayed on the screen and how content will be laid out. The default name given to a newly created folder is 'New Folder'.

'Alt + F4' is used to close the current window in Windows applications. The 'Layout' tab in MS Word 365 contains options to change page margins, orientation, and size.

If another presentation is already open, starting a new blank presentation in PowerPoint will open it in a new PowerPoint window. To customize bullets in MS Word, go to 'Home > Bullets > Define New Bullet'.

'Format Painter' is NOT a valid way to move selected text in MS Word. PCB stands for 'Printed Circuit Board'.

To create a new folder from the desktop in Windows 11, right-click, select 'New', then 'Folder'. The main purpose of the 'Taskbar' in Windows is to provide quick access to open and frequently used programs.

A touch screen can function as both an input and output device. A graphics card is NOT a part of the CPU.

Pressing 'Enter' while typing inside a text box in PowerPoint starts a new line within the same text box. The 'Format Painter' tool in MS Word copies formatting from one section of text to another.

Pressing 'Enter' in a text box in PowerPoint 2019 moves the cursor to the next line of the same text box. The correct way to save a new workbook is to click the 'File' tab and then 'Save As'.

A GPU (Graphical Processing Unit) is primarily responsible for rendering visual elements displayed on the monitor. 'Ctrl + Shift + V' performs 'Paste Special' in applications like Google Docs or web browsers where normal paste might not preserve desired formatting.

In a multitasking OS, RAM temporarily holds active program data and instructions, enabling rapid switching between tasks. 'Ctrl + O' is the shortcut to open an existing PowerPoint file directly from the application.

Page orientation in MS Word 2019 can be changed using the 'Page Layout' tab. The correct statement regarding RAM and ROM is that RAM temporarily stores data and active programs, while ROM permanently stores firmware.

The simplest way to rename a file is to right-click on it and select 'Rename'. The main purpose of 'cache memory' is to store frequently accessed data for quick retrieval.

'Ctrl + N' is used to quickly create a new blank PowerPoint presentation. The most effective way to organize files and folders in an OS is by creating a logical folder structure with clear, descriptive names.

The ALU (Arithmetic Logic Unit) handles calculations and logic operations, while the Control Unit manages instruction flow and coordination. 'Ctrl + F' is used to find text.

If a file is deleted and sent to the Recycle Bin, it can be restored by right-clicking it and selecting 'Restore'. To create a new text file in a Windows folder, open the folder, right-click, select 'New', then 'Text Document'.

The main purpose of the 'Tab' button on a standard keyboard is to move the cursor to the next field or tab position. Windows 10 is an example of a commonly used operating system on desktop computers.

'Ctrl + X' is the shortcut to cut text. The fundamental difference between input and output devices is that input devices enable users to send data to the computer, while output devices present processed data to the user.

A touch screen is considered both input and output because it allows users to interact with visual data and send touch signals. 'Ctrl + P' opens the print dialog box.
