Question 1Computer Fundamentals and Hardware

A student wants to store the binary value of decimal 45 in a single byte. Which 8-bit pattern represents 45 in unsigned binary?

  1. 00101101 Correct answer.
  2. 00101011
  3. 00110101
  4. 01001011

Explanation

Decimal 45 decomposes as 32 + 8 + 4 + 1, so the bits for places 32, 8, 4 and 1 are set (64, 16 and 2 remain 0). Reading place values 128 down to 1 gives 00101101. Checking the sum 32+8+4+1 confirms 45.

Question 2Computer Fundamentals and Hardware

In the CHSE IT syllabus treatment of computer generations, which technology is correctly paired with the generation in which it first dominated?

  1. Integrated circuits - third generation Correct answer.
  2. Microprocessors - second generation
  3. Transistors - fourth generation
  4. Vacuum tubes - second generation

Explanation

The standard generation sequence is vacuum tubes (first), transistors (second), integrated circuits (third), and microprocessors/VLSI (fourth). Integrated circuits therefore belong to the third generation. Each later generation brought smaller size, lower heat and greater reliability.

Question 3Computer Fundamentals and Hardware

Which unit inside a computer is responsible for fetching an instruction from memory, decoding it, and directing its execution?

  1. Accumulator register
  2. Memory Management Unit
  3. Control Unit Correct answer.
  4. Arithmetic Logic Unit

Explanation

The Control Unit coordinates the fetch-decode-execute cycle by issuing timing and control signals to other components. The ALU performs arithmetic and logic operations but does not decode instructions. The MMU handles address translation, and the accumulator only holds operands and results.

Question 4Computer Fundamentals and Hardware

A candidate is comparing primary and secondary memory. Which statement correctly describes a key difference between RAM and a hard disk?

  1. RAM is non-volatile while a hard disk loses its contents when power is switched off
  2. A hard disk is faster than RAM because it uses magnetic media
  3. RAM stores data permanently while a hard disk needs refreshing
  4. RAM is directly accessible by the CPU and is volatile, while a hard disk is non-volatile secondary storage Correct answer.

Explanation

RAM is semiconductor primary memory that the CPU addresses directly and whose contents vanish when power is removed. A hard disk is secondary storage that retains data without power but must be accessed through input/output operations. This combination of direct access plus volatility is what distinguishes RAM.

Question 5Computer Fundamentals and Hardware

Which of the following is an example of system software rather than application software?

  1. An operating system such as Linux Correct answer.
  2. A spreadsheet program used for marks calculation
  3. A web browser used for email
  4. A photo editing package

Explanation

System software manages hardware and provides a platform on which other programs run; an operating system is the classic example. Spreadsheets, browsers and photo editors are application software written to perform user tasks. The distinction rests on whether the program manages the machine or serves an end user directly.

Question 6Computer Fundamentals and Hardware

Which input device is most appropriate for reading the pre-printed marks sheet of an examination in which bubbles are filled with a pencil?

  1. Light pen
  2. Optical Mark Reader Correct answer.
  3. Bar code reader
  4. Digitizer tablet

Explanation

An Optical Mark Reader detects the presence or absence of marks at fixed positions on a form, which is exactly how bubble-type answer sheets are scored. Bar code readers decode stripes, digitizers capture freehand drawing, and light pens select positions on a screen. Only OMR is designed for positional pencil marks.

Question 7Computer Fundamentals and Hardware

Which of the following best describes the function of cache memory in a computer system?

  1. It holds frequently used instructions and data close to the CPU to reduce access time Correct answer.
  2. It converts analog signals into digital form
  3. It expands the capacity of the hard disk
  4. It permanently stores the operating system files

Explanation

Cache is a small, fast memory placed between the CPU and main memory that keeps recently or frequently used items. Because it is faster than RAM, a cache hit shortens the average time the CPU waits for data. It is volatile and does not store files permanently or extend disk capacity.

Question 8Computer Fundamentals and Hardware

A decimal number is repeatedly divided by 2 and the remainders are collected. Which conversion is being performed, and in what order should the remainders be read?

  1. Decimal to hexadecimal, read remainders bottom to top
  2. Binary to decimal, read remainders top to bottom
  3. Decimal to binary, read remainders bottom to top Correct answer.
  4. Decimal to octal, read remainders top to bottom

Explanation

Repeated division by 2 produces remainders that are the binary digits from least significant to most significant. The final quotient's remainder is the most significant bit, so remainders must be read from the last obtained to the first. Division by 8 or 16 would be used for octal or hexadecimal conversion.

Question 9Computer Fundamentals and Hardware

The hexadecimal value 2F is to be converted to decimal. What is the result?

  1. 31
  2. 47 Correct answer.
  3. 62
  4. 45

Explanation

In hexadecimal the digit F stands for 15, and the place values are 16 and 1. So 2F equals 2×16 + 15 = 32 + 15 = 47. Converting to binary first (0010 1111 = 32+8+4+2+1) gives the same total.

Question 10Computer Fundamentals and Hardware

A byte 11010110 is interpreted as a signed 8-bit number in two's complement form. What decimal value does it represent?

  1. 214
  2. -74
  3. -41
  4. -42 Correct answer.

Explanation

The leading bit is 1, so the value is negative. Inverting the bits gives 00101001 and adding 1 gives 00101010, which is 42; therefore the original pattern represents -42. Equivalently, -128 + 64 + 16 + 4 + 2 = -42.

Question 11Computer Fundamentals and Hardware

Which statement about the fetch-decode-execute cycle is correct?

  1. Decoding is performed by the ALU before the instruction is fetched
  2. The instruction register stores the address of the next instruction
  3. Execution always writes a result back to secondary storage
  4. The program counter holds the address of the next instruction to be fetched Correct answer.

Explanation

During fetch, the Program Counter supplies the address of the instruction to memory, and the PC is then incremented. The Instruction Register receives the fetched instruction itself and holds it for decoding by the control unit. Execution results normally go to registers or main memory, not directly to secondary storage.

Question 12Computer Fundamentals and Hardware

Which characteristic distinguishes SRAM from DRAM in a typical computer?

  1. SRAM is faster and needs no refreshing, but is costlier per bit Correct answer.
  2. SRAM uses capacitors and needs constant refreshing
  3. DRAM is non-volatile and keeps data without power
  4. DRAM is used for cache while SRAM forms the main memory

Explanation

SRAM cells are built from flip-flop circuits that hold a bit as long as power is applied, so no refresh is needed and access is fast, but each cell uses more transistors and costs more. DRAM stores charge in capacitors, must be refreshed, and is cheaper and denser, which suits main memory. Both are volatile.

Question 13Computer Fundamentals and Hardware

A computer has 12 address lines. What is the maximum number of distinct memory locations it can address directly?

  1. 8192
  2. 2048
  3. 1024
  4. 4096 Correct answer.

Explanation

Each address line doubles the number of addressable locations, so n lines give 2^n locations. With 12 lines this is 2^12 = 4096. The width of each location (word size) affects total capacity in bytes but not the count of addresses.

Question 14Computer Fundamentals and Hardware

Which of the following correctly orders the storage devices from fastest to slowest access?

  1. Solid-state drive, cache, main memory, magnetic hard disk
  2. Cache, main memory, solid-state drive, magnetic hard disk Correct answer.
  3. Magnetic hard disk, solid-state drive, cache, main memory
  4. Main memory, cache, magnetic hard disk, solid-state drive

Explanation

The memory hierarchy places the fastest and smallest storage nearest the CPU. Cache is fastest, followed by RAM, then flash-based SSDs, and finally mechanical hard disks with moving heads. This ordering also roughly follows increasing cost per bit decreasing and capacity increasing.

Question 15Computer Fundamentals and Hardware

A dot-matrix printer is chosen for printing multi-part carbon invoices in a school office. Which property of the device makes it suitable?

  1. It strikes a ribbon against the paper, creating an impact that transfers to all copies Correct answer.
  2. It sprays tiny ink droplets through fine nozzles
  3. It produces high-resolution photographic colour output
  4. It uses a laser and toner to fuse images onto paper

Explanation

Dot-matrix printers are impact printers: pins strike an inked ribbon and the mechanical impact marks the carbon copies beneath the top sheet. Laser printers use toner and heat, and inkjet printers spray droplets; neither can create multi-part carbon copies. This impact property is the reason such printers survive in billing and examination offices.

Question 16Computer Fundamentals and Hardware

Which of the following correctly states the purpose of an interrupt in a computer system?

  1. To allocate disk blocks to a newly created file
  2. To convert a high-level program into machine code before execution
  3. To signal the CPU that an event needs attention so it can suspend the current task and service it Correct answer.
  4. To increase the clock speed of the processor during heavy load

Explanation

An interrupt is a signal, from hardware or software, that temporarily diverts the CPU from its current program. The CPU saves its state, runs the appropriate interrupt service routine, and then resumes. This mechanism lets devices request service without the CPU constantly polling them.

Question 17Computer Fundamentals and Hardware

A school purchases a pen drive labelled 64 GB. Which explanation best accounts for the usable formatted capacity being slightly less than 64 GB?

  1. The USB interface loses one byte in every thousand during transfer
  2. The drive contains cache memory that reduces its capacity
  3. Flash memory always reserves exactly half its capacity for error correction
  4. Manufacturers count 1 GB as 10^9 bytes while the operating system reports using powers of 2, and file-system structures consume some space Correct answer.

Explanation

Drive makers usually define 1 GB as one billion bytes, whereas an operating system reports GiB (2^30 bytes), so the same physical capacity shows a smaller number. Formatting also writes file-system metadata that occupies some space. The difference is a matter of units and overhead, not data loss.

Question 18Computer Fundamentals and Hardware

Which of the following is the correct expansion and role of BIOS in a personal computer?

  1. Basic Input Output System; firmware that initialises hardware and starts the boot process Correct answer.
  2. Basic Integrated Operating System; a graphical shell loaded after login
  3. Binary Input Output Storage; a partition where the operating system is installed
  4. Buffered Input Output Service; a driver that controls only the printer

Explanation

BIOS stands for Basic Input Output System and is firmware stored on a chip on the motherboard. At power-on it runs the power-on self-test, initialises essential hardware, and hands control to the boot loader. Modern systems often use UEFI firmware for the same role.

Question 19Computer Fundamentals and Hardware

Which motherboard component is used to hold the processor and provides the electrical connections between the processor and the rest of the board?

  1. CPU socket Correct answer.
  2. DIMM slot
  3. CMOS battery
  4. PCIe slot

Explanation

The CPU socket is the mechanical and electrical receptacle into which the processor is seated. PCIe slots accept expansion cards, DIMM slots hold memory modules, and the CMOS battery maintains clock and setup settings. Only the socket is designed for the processor itself.

Question 20Computer Fundamentals and Hardware

A user reports that the computer powers on, the fans spin, but nothing appears on the monitor and no beep is heard. Which component should be checked first as the most likely cause of a failure before the boot process completes?

  1. The hard disk's file system
  2. The printer driver installation
  3. The screen saver settings
  4. The RAM modules and their seating in the DIMM slots Correct answer.

Explanation

POST runs before any operating system loads, so file-system, driver and screen-saver settings cannot be the cause at this stage. Memory faults or poorly seated RAM commonly stop POST before video initialisation, producing a blank screen. Reseating or swapping RAM modules is the standard first diagnostic step.

Question 21Computer Fundamentals and Hardware

A logic circuit is required whose output is 1 only when both of its two inputs are 1. Which gate implements this, and what is its Boolean expression?

  1. AND gate, output A · B Correct answer.
  2. OR gate, output A + B
  3. XOR gate, output A ⊕ B
  4. NOT gate, output A'

Explanation

The AND gate produces a high output only when every input is high, written as A · B. The OR gate is high when at least one input is high, and XOR is high when the inputs differ. A NOT gate has a single input and inverts it.

Question 22Computer Fundamentals and Hardware

In the IEEE 754 single-precision format, how many bits are allocated to the sign, exponent and fraction fields respectively?

  1. 1, 8, 23 Correct answer.
  2. 2, 8, 22
  3. 1, 11, 20
  4. 1, 7, 24

Explanation

Single precision uses 32 bits in total: one sign bit, eight exponent bits with a bias of 127, and twenty-three fraction bits. The double-precision format instead uses 1, 11 and 52 bits. Remembering that the fields sum to 32 helps confirm the split.

Question 23Computer Fundamentals and Hardware

A hard disk has 4 platters, 512 tracks per surface, and 64 sectors per track, with 512 bytes per sector. Using both surfaces of every platter, what is the approximate unformatted capacity?

  1. 512 MB
  2. 64 MB
  3. 128 MB Correct answer.
  4. 256 MB

Explanation

Four platters give eight recording surfaces. Capacity = surfaces × tracks × sectors × bytes = 8 × 512 × 64 × 512 bytes = 134,217,728 bytes, which is 128 MiB. Multiplying the factors step by step (8×512 = 4096 tracks, ×64 = 262,144 sectors, ×512 bytes) confirms the result.

Question 24Computer Fundamentals and Hardware

A program contains a loop that is executed many times, and the designer wants the frequently executed loop body to remain in fast memory. Which memory arrangement best achieves this, and why?

  1. Place the loop in a slower secondary store so that it is protected from overwriting
  2. Rely on cache locality so that the repeatedly used instructions stay in cache across iterations Correct answer.
  3. Increase the number of address lines so that the loop occupies more addresses
  4. Move the loop into ROM so that it can be read faster than RAM

Explanation

Temporal locality means recently executed instructions are likely to be executed again, so a loop body tends to stay resident in cache after the first iteration. This reduces average access time without any program change. Secondary storage is far slower, extra address lines add no speed, and ROM is generally not faster than cache.

Question 25Operating Systems and File Management

In a typical Windows file system, which character is used to separate the drive letter from the directory path in a location such as C:\Users\Student?

  1. The pipe (|)
  2. The forward slash (/)
  3. The colon (:)
  4. The backslash (\) Correct answer.

Explanation

Windows uses the backslash as the path separator, so a full path appears as C:\Users\Student. The colon only follows the drive letter to mark the volume, and the forward slash is the separator used in Linux and other Unix-like systems.

Question 26Operating Systems and File Management

A student wants to rename a folder in Windows File Explorer while keeping its contents unchanged. Which action accomplishes this?

  1. Select the folder and press Ctrl+C, then Ctrl+V
  2. Drag the folder into the Recycle Bin and restore it
  3. Select the folder, press Delete, and then create a new folder with the new name
  4. Select the folder, press F2, type the new name, and press Enter Correct answer.

Explanation

The F2 key in Windows File Explorer places the selected item's name in edit mode without altering its contents. Typing a new name and pressing Enter renames the folder while its files remain inside. The other actions either remove the folder or copy it rather than renaming it.

Question 27Operating Systems and File Management

Which of the following best describes the function of an operating system's file management component?

  1. It organises, stores, retrieves, and tracks files and folders on storage devices Correct answer.
  2. It manages the physical cooling of the processor
  3. It assigns IP addresses to devices on a network
  4. It converts high-level source code into machine instructions

Explanation

File management is responsible for creating, naming, storing, locating, and tracking files and directories on storage media. Compilation, thermal control, and network addressing belong to other system or application functions, not file management.

Question 28Operating Systems and File Management

In Windows, what is the primary purpose of the Recycle Bin?

  1. To compress files so they occupy less disk space
  2. To hold files that are currently open by another program
  3. To store backup copies of the operating system files
  4. To temporarily hold deleted files so they can be restored before permanent removal Correct answer.

Explanation

When a file is deleted in Windows, it is moved to the Recycle Bin rather than erased immediately, allowing the user to restore it. Files remain there until the bin is emptied or its size limit is exceeded. It is not a backup, compression, or file-locking mechanism.

Question 29Operating Systems and File Management

Which file extension typically identifies a plain text file that can be opened in Notepad without special formatting?

  1. .exe
  2. .dll
  3. .txt Correct answer.
  4. .iso

Explanation

The .txt extension marks a plain text file containing unformatted characters, which Notepad can open directly. The .exe and .dll extensions denote executable and library files, and .iso denotes a disc image.

Question 30Operating Systems and File Management

Which key combination is commonly used in Windows to copy selected files to the clipboard without removing them from their original location?

  1. Ctrl+Z
  2. Ctrl+C Correct answer.
  3. Ctrl+V
  4. Ctrl+X

Explanation

Ctrl+C copies the selected items to the clipboard while leaving the originals in place. Ctrl+X cuts them for moving, Ctrl+V pastes, and Ctrl+Z undoes the last action.

Question 31Operating Systems and File Management

A user has a folder named Reports on drive D:. They want a shortcut on the Desktop that opens this folder quickly. Which approach is correct?

  1. Right-click the folder, choose Send to, then Desktop (create shortcut) Correct answer.
  2. Copy the folder and paste it onto the Desktop
  3. Move the folder to the Desktop
  4. Rename the folder to Desktop

Explanation

The Send to > Desktop (create shortcut) command creates a link that points to the original folder while leaving its contents in place. Copying duplicates the data, moving relocates it, and renaming does not create any link.

Question 32Operating Systems and File Management

What distinguishes an absolute path from a relative path in a file system?

  1. An absolute path always uses fewer characters than a relative path
  2. An absolute path starts from the root or drive and is valid regardless of the current directory Correct answer.
  3. A relative path can only refer to files, never to folders
  4. A relative path always begins with a drive letter

Explanation

An absolute path specifies the complete location starting from the root directory or drive letter, so it resolves the same way from any current directory. A relative path is interpreted from the current working directory and therefore depends on where the user is. Length and file type do not determine which kind of path is used.

Question 33Operating Systems and File Management

Which Windows file attribute prevents a file from being modified until the attribute is cleared, while still allowing it to be read?

  1. Read-only Correct answer.
  2. Hidden
  3. System
  4. Archive

Explanation

The read-only attribute blocks changes to a file's contents while permitting it to be opened and read. Hidden controls visibility in listings, Archive marks files for backup tools, and System marks files used by the operating system.

Question 34Operating Systems and File Management

A user searches for *.docx in a folder. Which files will the search return?

  1. All folders that contain docx files
  2. Only files named exactly docx
  3. All files whose names contain the letters docx anywhere
  4. Only files whose names end with the .docx extension Correct answer.

Explanation

In wildcard searching, the asterisk matches any sequence of characters, so *.docx matches every file name ending in .docx. The pattern does not match names merely containing docx elsewhere, and it targets files rather than folders containing them.

Question 35Operating Systems and File Management

What is the main advantage of the NTFS file system over FAT32 on a Windows computer?

  1. It can be read by any device without drivers
  2. It removes the need for folders entirely
  3. It stores files only in RAM for faster access
  4. It supports file permissions, larger files, and journaling for better reliability Correct answer.

Explanation

NTFS provides access control lists, support for very large volumes and files, and journaling that helps recover from crashes. FAT32 lacks these features and limits individual file size to about 4 GB. Neither file system stores data only in RAM or eliminates folders.

Question 36Operating Systems and File Management

A student wants to free disk space by removing temporary files created by Windows and applications. Which built-in tool is designed for this purpose?

  1. Disk Cleanup Correct answer.
  2. Device Manager
  3. Task Manager
  4. Character Map

Explanation

Disk Cleanup scans a drive for temporary files, cached data, and other unneeded items and lets the user delete them to reclaim space. Device Manager manages hardware, Task Manager monitors running processes, and Character Map inserts special characters.

Question 37Operating Systems and File Management

Which statement correctly describes how folders differ from files?

  1. Folders and files are identical in function but differ in name length
  2. Folders can only exist on removable drives, while files exist on internal drives
  3. Folders group files and other folders, while files hold data such as text or images Correct answer.
  4. Folders hold data, while files only hold other folders

Explanation

A folder is a container used to organise files and subfolders, whereas a file stores actual content such as text, images, or programs. Folders do not themselves contain user data, and both types can reside on any storage device.

Question 38Operating Systems and File Management

A user copies a file from an NTFS drive to a FAT32 USB drive. The file is 6 GB in size. What is the most likely outcome?

  1. The file is compressed to fit within the FAT32 limit
  2. The copy fails because FAT32 cannot store a single file larger than about 4 GB Correct answer.
  3. The file is copied successfully because file size limits apply only to NTFS
  4. The file is automatically split into two parts by Windows

Explanation

FAT32 enforces a maximum file size of roughly 4 GB, so a 6 GB file cannot be written to a FAT32 volume. Windows reports an error rather than splitting or compressing the file automatically. The limitation belongs to FAT32, not NTFS.

Question 39Operating Systems and File Management

A file named notes.txt is created inside C:\School\IT. Which of the following is the full path of this file?

  1. C:\School\IT\notes.txt Correct answer.
  2. notes.txt\C:\School\IT
  3. C:\notes.txt\School\IT
  4. School\notes.txt

Explanation

A full path lists the drive, then each folder from the root down to the file, with backslashes separating the components. The file name appears last, so C:\School\IT\notes.txt is correct. The other options place the file name or folders in the wrong order.

Question 40Operating Systems and File Management

What does the file extension in a name such as report.pdf tell the operating system?

  1. The date on which the file was last modified
  2. The user account that created the file
  3. Which application is associated with opening the file by default Correct answer.
  4. The exact size of the file in bytes

Explanation

The extension associates a file with a default application, so double-clicking report.pdf opens a PDF reader. File size, modification date, and owner are stored as separate metadata and are not encoded in the extension.

Question 41Operating Systems and File Management

A user deletes a file by pressing Shift+Delete in Windows File Explorer. What is the result?

  1. The file is moved to the Recycle Bin and can be restored
  2. The file is renamed with a .bak extension
  3. The file is moved to the Desktop
  4. The file is removed permanently without being placed in the Recycle Bin Correct answer.

Explanation

Shift+Delete bypasses the Recycle Bin and deletes the file directly, so it cannot be restored from the bin. A normal Delete key press sends the file to the Recycle Bin instead. Renaming and moving to the Desktop are unrelated actions.

Question 42Operating Systems and File Management

Which of the following best explains why two files with the same name cannot exist in the same folder on a Windows NTFS volume?

  1. Windows automatically renames the second file by appending a random number
  2. The file system stores only one file per folder regardless of size
  3. The folder acts as a namespace in which each name must be unique, though the same name may appear in a different folder Correct answer.
  4. NTFS forbids all duplicate names on an entire drive, including different folders

Explanation

Within a single directory, the file name is the key that identifies an entry, so names must be unique there. The same name can be reused in a different directory because the full path differs. NTFS does not restrict duplicates across the whole drive, and it does not silently rename files.

Question 43Operating Systems and File Management

A user reports that a file they can see in File Explorer cannot be deleted because it is 'in use by another program'. Which explanation is most accurate?

  1. The file extension is not recognised, so the system refuses to delete it
  2. The file has been marked read-only, which prevents deletion by any user
  3. The file is stored on a FAT32 volume, which never allows deletion
  4. An open process holds a lock on the file, so the operating system blocks deletion until the handle is released Correct answer.

Explanation

When a program opens a file, the operating system grants it a handle and may lock the file against deletion. Closing the program releases the handle and allows deletion. Read-only attributes can be cleared, FAT32 supports deletion, and unknown extensions do not block removal.

Question 44Operating Systems and File Management

Which sequence of steps correctly creates a new folder inside an existing folder in Windows File Explorer?

  1. Right-click the existing folder and choose Delete, then create a new folder elsewhere
  2. Double-click the existing folder until it opens in a new window, then press F5
  3. Open the existing folder, right-click an empty area, choose New, then Folder, type a name, and press Enter Correct answer.
  4. Open the existing folder and press Ctrl+V without copying anything first

Explanation

The New > Folder command in the context menu creates a subfolder in the current location, after which the user types a name and confirms with Enter. Deleting, pasting with an empty clipboard, or refreshing the view does not create a folder.

Question 45Word Processing and Documentation

In a word processor, which feature automatically moves a word that does not fit at the end of a line down to the beginning of the next line?

  1. Track changes
  2. Spell check
  3. Mail merge
  4. Word wrap Correct answer.

Explanation

Word wrap is the automatic line-breaking behaviour of a word processor: when the current line is full, the whole word is carried to the next line without the user pressing Enter. Manual line breaks inserted with Enter are called hard returns and are not the same thing.

Question 46Word Processing and Documentation

Which alignment setting produces text that is flush with both the left and right margins by adding extra space between words?

  1. Right aligned
  2. Centred
  3. Left aligned
  4. Justified Correct answer.

Explanation

Justified alignment stretches or compresses the spaces between words so that every line except the last is flush with both margins. Left, right and centred alignment leave one or both edges ragged, so they cannot produce even edges on both sides.

Question 47Word Processing and Documentation

A student wants every page of a report to show the title and page number at the top. Which part of the document should be edited?

  1. Footer
  2. Header Correct answer.
  3. Footnote
  4. Endnote

Explanation

The header is the area at the top of each page that repeats automatically on every page of the section. Editing it once applies the content to all pages that share that header.

Question 48Word Processing and Documentation

What is the main purpose of the Find and Replace dialog in a word processor?

  1. To locate specified text and optionally substitute other text for it Correct answer.
  2. To convert the document to a different file format
  3. To change the font of the whole document at once
  4. To compare two documents and list their differences

Explanation

Find and Replace searches the document for a specified string and can substitute a replacement string wherever it occurs, either one at a time or all at once. It works on text content, not on formatting of the whole document or on file conversion.

Question 49Word Processing and Documentation

Which file extension is the default native format for a document saved by common word processing software such as LibreOffice Writer?

  1. .odt Correct answer.
  2. .odp
  3. .odg
  4. .ods

Explanation

The OpenDocument family uses distinct extensions per application: .odt for text documents, .ods for spreadsheets, .odp for presentations and .odg for drawings. A word-processed document therefore uses .odt.

Question 50Word Processing and Documentation

In a word processor, what does a paragraph style store?

  1. The keyboard shortcut assigned to a menu command
  2. A list of words added to the spell-check dictionary
  3. Only the font name and size of the selected characters
  4. A named set of formatting attributes applied to whole paragraphs Correct answer.

Explanation

A paragraph style is a named collection of paragraph-level and character-level settings, such as alignment, spacing, indents and font, that is applied to an entire paragraph. Because the settings are stored in the style, changing the style updates every paragraph that uses it.
