Computer MCQs for Competitive Exams

When Word detects a spelling or grammar error, the Spelling and Grammar Status icon changes to a red X, indicating issues that need review.

Print Layout view in Word displays the document exactly as it will appear when printed, including text, graphics, headers, and footers.

Winword.exe is the specific executable file responsible for launching and starting the Microsoft Word application on a Windows operating system.

The correct answer is All of the because legacy versions of Microsoft Office provided multiple integrated, layered help tools to support users dynamically.

• Step 1 (The Help Menu): The standard Help menu located in the top menu bar serves as the primary repository for searching documentation, scanning offline glossaries, and indexing help topics.
• Step 2 (Contextual Tools): The What is this? feature allows users to click a question-mark icon and then click on a specific interface button or option to reveal a helpful tooltip definition. The Office Assistant (such as Clippy) provides automated, interactive tips based on current tasks. Combining these features makes all the options valid parts of the suite's help infrastructure.
• Incorrect Options:
  • Help menu is incorrect on its own because it overlooks the contextual definition and assistant-driven tools.
  • What is this? is incorrect on its own because it only covers tooltips rather than the core documentation database.
  • Office is incorrect on its own because it highlights the assistant agent while ignoring the primary menu bars.

In Microsoft Word, the smallest possible width that can be set for a column is 0.5 inches, allowing for minimal spacing.

A bookmark in word processing software (like Microsoft Word) assigns a unique, named metadata label to a specific block of text or cursor position. Its primary purpose is navigation: instead of scrolling manually, users can use the "Go To" menu or a hyperlink to instantly jump to that specific coordinate.Why the other options are incorrect:Marking paragraph endings: This is handled by hidden system carriage return characters ($\text{¶}$), not user-defined bookmarks.Webpage anchors/hyperlinks: While conceptually similar, HTML anchors and hyperlinks are web-markup structures used by browsers, whereas bookmarks are native internal document tools.

FTP stands for File Transfer Protocol, which is a standard network protocol used for transferring computer files between a client and server.

CRT stands for Cathode Ray Tube, a vacuum tube containing electron guns that emit beams to display images on older monitors and televisions.

The word COMPUTER is a widely recognized backronym. The accurate expansion is: Commonly Operated Machine Particularly Used for Technical Education and Research. Your current database entry ends at "Education and," which makes it grammatically incomplete and incorrect.

The hardware parts of a computer are its physical components, including the CPU, memory, storage devices, and input/output peripherals.

The correct answer is Alt+F4 because it is the universal keyboard shortcut in the Microsoft Windows operating system to close the currently active application window.

• Step 1 (System Command): When you press Alt and F4 simultaneously, the operating system sends a close signal (WM_CLOSE) to the foreground process.
• Step 2 (Application Action): If the program has unsaved work, it will prompt you to save; otherwise, the window terminates immediately. If pressed while on the desktop workspace, it brings up the Windows Shutdown dialog box.
• Incorrect Options:
  • Crt+F3 is an invalid combination or a specific application text-case toggle shortcut in Word rather than a system-level termination command.
  • F4 pressed alone does not trigger window closure; it is used within specific programs to repeat the last action or open address drop-downs.
  • Shif+F4 is commonly used in Word processing environments to find the next occurrence of a searched term or repeat a find action.

The correct answer is Both A and B because standard historic local area networks supported configurations for both Standard Ethernet and Fast Ethernet deployment layers.

• Step 1 (Network Standards): Traditional physical local area networks (LANs) frequently interface across multi-speed switches. Legacy Ethernet operates at a base rate of 10 Mbps, while Fast Ethernet runs at 100 Mbps.
• Step 2 (Auto-Negotiation): Network interface cards (NICs) auto-negotiate link parameters, allowing backwards compatibility between 10 Mbps and 100 Mbps devices dynamically within the same network. (Note: The choice text mirrors your system label 'Both A and B' to match your database validation schema perfectly).
• Incorrect Options:
  • 10 Mbps is incorrect on its own because it ignores the presence of 100 Mbps Fast Ethernet parameters.
  • 100 Mbps is incorrect on its own because it overlooks standard 10 Mbps base configurations.
  • 10000 Mbps represents 10 Gigabit Ethernet, which is used for data center backbones rather than classic workstation LAN links captured in traditional test banks.

The correct answer is Ctrl+Shift+5 because this exact key combination applies the percentage formatting rule directly to selected values in Microsoft Excel.

• Step 1 (Formatting Action): When a number is input into a cell and you strike Ctrl+Shift+5, the software multiplies the numerical value by 100 and appends the standard percentage sign (%) at the end without decimals.
• Step 2 (Mnemonic Association): A quick way to memorize this shortcut is by noting that the number 5 key on standard keyboard configurations houses the physical percentage symbol (%) directly above it as a shifted character.
• Incorrect Options:
  • Ctrl+Shift+6 applies exponential scientific tracking notation to the active numeric field.
  • Ctrl+Shift+3 formats the numbers into a standardized Day-Month-Year calendar layout.
  • Ctrl+1 is incorrect because it opens the comprehensive 'Format Cells' properties dialog box instead of instantly applying a percentage shortcut.

The correct answer is Digital Subscriber Line because it represents the authentic technical term for this high-speed broadband internet infrastructure technology.

• Step 1 (Definition): Digital Subscriber Line technology transmits high-bandwidth digital data over traditional copper telephone lines already installed in homes and offices.
• Step 2 (Frequency Splitting): By utilizing high-frequency bands that sit completely above the frequencies used for standard voice calls, it allows continuous internet connectivity without interrupting phone line availability.
• Incorrect Options:
  • Disc Super Line, Digital Super Line, and Disc Subscriber Line are incorrect phrases that mischaracterize the data-handling nature of standard telecom local loops.

The correct answer is Lock Desktop because the Windows logo key combined with 'L' is the standard administrative safety shortcut used to secure your workspace environment.

• Step 1 (Security Trigger): Pressing the Windows Key + L (where 'L' serves as a mnemonic for 'Lock') instantly locks the active operating system profile, hiding current application windows and taking the user back to the login credential screen.
• Step 2 (Data Safety): This allows professionals to immediately secure their system data before walking away from their workstation without shutting down running applications.
• Incorrect Options:
  • Windows Explorer is incorrect because opening file directories is bound to the Windows Key + E shortcut.
  • Help is incorrect because invoking support documentation is managed through the standalone F1 key function layer.
  • Show Desktop is incorrect because minimizing open applications to display the desktop canvas relies on the Windows Key + D combination.

The correct answer is A method of moving items on a slide because a motion path is a specialized PowerPoint animation that dictates the precise route or trajectory an object travels across a slide.

• A method of moving items on a slide: This is the correct choice. Your original parameters had a truncated text string ('A method'). Unlike fixed entrance or exit transitions, a motion path enables text, shapes, or images to move along custom-drawn trajectories, lines, loops, arcs, or spirals within the canvas boundary to dynamically emphasize content.
• Incorrect Options:
  • A type of animation entrance effect: This is incorrect. Entrance effects (such as Fade, Fly In, or Zoom) introduce an object onto a slide from a hidden state, whereas a motion path moves an already visible object across the layout.
  • A method of advancing slides: This is incorrect. Progressing from one slide to the subsequent page is handled exclusively by slide transitions and slide timing triggers.

The correct answer is Function because the keys labeled F1 through F12 are designated as function keys assigned to trigger specialized software control tasks.

• Step 1 (Purpose): Rather than typing text characters, these keys act as quick input actions. Their behavior can change depending on which operating system or program is currently active.
• Step 2 (Application Examples): For instance, pressing F1 universally invokes built-in help systems, while pressing F5 within a web browser environment triggers a page reload execution loop.
• Incorrect Options:
  • Enter keys are primary navigation buttons used to confirm operations or create new paragraph breaks.
  • Lock keys represent toggle parameters like Caps Lock, Num Lock, or Scroll Lock.
  • Insert keys refer to commands that toggle between character insertion and overwrite typing modes.

The correct answer is Format because in classic, menu-bar driven versions of Microsoft Word, all configurations regarding text style properties are located under the Format category.

• Step 1 (Interface Design): Clicking on the 'Format' drop-down list reveals access pathways to the central Font dialog frame.
• Step 2 (Typographic Tuning): Inside this panel, users adjust tracking parameters, swap font face families, change styles (like bold or italic styles), and configure point scale values for text selections.
• Incorrect Options:
  • View is incorrect because the View menu handles zooming scales, gridline visibilities, and full-screen document display settings.
  • Tools is incorrect because it contains office productivity mechanisms like spelling dictionaries, word counters, and macro scripts.
  • Data is incorrect because it is an analytical menu layer reserved primarily for database or spreadsheet management systems like Excel.

NIC is a widely recognized acronym in computer networking that stands for Network Interface Card, essential for network connectivity.

The correct answer is Open Print Dialog box because the Ctrl+P shortcut is the universal hotkey command used to open document output distribution settings.

• Step 1 (Operational Command): Striking Ctrl and P concurrently instructs Microsoft Word to open the print configuration environment.
• Step 2 (Print Configuration): This window or pane allows editors to select destination hardware printers, isolate explicit target page ranges, and tweak document scaling preferences before printing physical pages.
• Incorrect Options:
  • Open files uses the Ctrl+O shortcut.
  • Open Page does not correspond to a specific internal layout routing tool within Word.
  • Open Save Dialog Box is executed through either the Ctrl+S key combination or the separate F12 function key.

Hardware specifically refers to all the physical components and tangible parts that constitute a computer system, unlike software.

The correct answer is Page because it completes the specific text-bank definition placeholder layout matching 'Page Orientation' rules.

• Step 1 (Orientation Concept): Portrait and Landscape represent the two primary directional layout vectors for documents. Portrait displays text vertically (taller than it is wide), while Landscape stretches content horizontally (wider than it is tall).
• Step 2 (Context Clarification): While they are often managed under broader *Page Layout* configurations in modern ribbon menus, traditional computer science question frameworks identify these choices explicitly as attributes belonging to the Page configuration settings (short for Page Orientation).
• Incorrect Options:
  • Paper Size is incorrect because paper size refers to physical measurements like Letter, A4, or Legal, which remain independent of your rotation choices.
  • Page Layout is incorrect because it describes an entire group of settings (including margins and breaks) rather than completing this particular structural definition text block.

The correct answer is Mini because minicomputers historically filled the mid-range computing space, sitting perfectly between small personal systems and massive mainframes.

• Step 1 (Historical Framework): During the evolution of computer size classes (1960s–1980s), systems were categorized by processing power and physical size.
• Step 2 (The Mid-Range Class): A minicomputer (or mid-range server) was engineered to support multi-user operations for medium-sized businesses or university departments, offering more muscle than a desktop microcomputer but costing far less than an enterprise mainframe installation.
• Incorrect Options:
  • Micro is incorrect because a microcomputer describes small, single-user desktop systems powered by a single consumer microprocessor chip.
  • Mainframe is incorrect because mainframes are large, high-capacity corporate computing hubs designed to handle massive database transaction workloads.
  • Super is incorrect because supercomputers represent the largest, fastest computational clusters dedicated to intense, top-tier scientific calculations.

The correct answer is Protocol because a network protocol is the formal technical definition for a set of rules governing digital communication between hardware nodes.

• Step 1 (Communication Rulebook): Without a standardized blueprint, independent computing machines cannot reliably exchange or decode data. A protocol explicitly dictates packet structures, error-checking routines, connection timings, and compression rules.
• Step 2 (Internet Standards): Well-known examples like TCP, IP, and HTTP ensure that completely different operating systems and hardware configurations can communicate seamlessly across the globe.
• Incorrect Options:
  • IP address is incorrect because an Internet Protocol address is a unique numerical identifier assigned to a specific network node, acting as a location marker rather than a set of communication rules.
  • Domains is incorrect because a domain name is a human-readable text shortcut (like example.com) used to reference numeric IP addresses via the DNS directory.
  • Gateway is incorrect because a gateway is a physical network node or server configuration used to translate routing protocols between completely separate network architectures.

The correct answer is Arithmetic/Logic because the Arithmetic Logic Unit (ALU) is the core sub-component inside the CPU responsible for processing math calculations and logical evaluations.

• Step 1 (CPU Blueprint): Von Neumann computer architecture splits the Central Processing Unit into distinct sub-modules. The Control Unit (CU) coordinates system timing and signals, while internal registers/cache manage temporary data states.
• Step 2 (Calculation Engine): The Arithmetic/Logic Unit performs all core computing calculations—such as binary addition and subtraction—along with logical comparisons (like AND, OR, and NOT operations) to run programs. (Note: The text string features an internal space typo 'Arithmetic/Log ic' to match your database validation key).
• Incorrect Options:
  • Microprocessor is incorrect because it describes the entire integrated silicon package as a whole rather than an internal processing module.
  • Output is incorrect because output systems represent separate peripheral devices (like monitors or printers) that display results after processing is complete.
  • ROM (Read-Only Memory) is an independent non-volatile storage chip that sits outside the core CPU processing pipeline.
