Question 1Information Technology Fundamentals and Computer Systems

In a computer system, which component is primarily responsible for executing program instructions and performing arithmetic and logical operations?

  1. The hard disk drive
  2. The central processing unit Correct answer.
  3. The power supply unit
  4. The random access memory

Explanation

The central processing unit fetches, decodes and executes instructions and contains the arithmetic logic unit that performs calculations and comparisons. Other components store data or supply power but do not execute instructions.

Question 2Information Technology Fundamentals and Computer Systems

Which of the following best describes the function of RAM in an ITeS workstation?

  1. It connects the computer to the local area network
  2. It converts digital signals into analog output for the monitor
  3. It permanently stores the operating system files
  4. It holds programs and data currently in use for fast access by the CPU Correct answer.

Explanation

RAM is volatile working memory that holds instructions and data the CPU is actively using, giving much faster access than secondary storage. Its contents are lost when power is removed, so it is not permanent storage.

Question 3Information Technology Fundamentals and Computer Systems

A company wants storage that has no moving parts, offers very fast read/write speeds, and is commonly used to boot operating systems quickly. Which technology fits best?

  1. Floppy disk
  2. Optical DVD
  3. Solid state drive Correct answer.
  4. Magnetic tape

Explanation

A solid state drive uses flash memory with no mechanical parts, giving low latency and high throughput, which shortens boot times. Tape, DVD and floppy disks are slower removable or sequential media.

Question 4Information Technology Fundamentals and Computer Systems

Which number system is the native representation used internally by digital computers because it maps directly onto two-state electronic circuits?

  1. Decimal
  2. Roman
  3. Binary Correct answer.
  4. Hexadecimal

Explanation

Digital circuits have two stable states, so binary digits 0 and 1 map directly onto those states. Hexadecimal is a compact shorthand for binary used by humans, and decimal requires conversion.

Question 5Information Technology Fundamentals and Computer Systems

In an ITeS delivery centre, which device is a typical example of an input peripheral?

  1. A monitor
  2. A laser printer
  3. A speaker
  4. A barcode scanner Correct answer.

Explanation

Input peripherals send data from the outside world into the computer, and a barcode scanner converts printed codes into digital data. Printers, monitors and speakers are output devices.

Question 6Information Technology Fundamentals and Computer Systems

Which type of software is an operating system such as Windows or Linux classified as?

  1. System software Correct answer.
  2. Utility firmware
  3. Application software
  4. Programming language

Explanation

An operating system is system software because it manages hardware resources and provides services for application programs. Application software performs user-facing tasks, while a programming language is a notation for writing code.

Question 7Information Technology Fundamentals and Computer Systems

Which protocol is used by a web browser to request and receive web pages from a web server?

  1. FTP
  2. HTTP Correct answer.
  3. DHCP
  4. SMTP

Explanation

HTTP, and its secure form HTTPS, defines how browsers request resources from web servers and how servers respond. FTP transfers files, SMTP sends mail and DHCP assigns network addresses.

Question 8Information Technology Fundamentals and Computer Systems

An employee stores a spreadsheet on a network file server so that colleagues in another office can open the same file. Which characteristic of the file server makes this possible?

  1. It encrypts every file automatically without configuration
  2. It replaces the need for an operating system on clients
  3. It increases the clock speed of the client computers
  4. It provides shared, centrally managed storage accessible over the network Correct answer.

Explanation

A file server offers shared storage that multiple authorised clients can reach across a network, enabling collaboration from different locations. It does not change client processor speed or remove the need for a client operating system.

Question 9Information Technology Fundamentals and Computer Systems

Convert the binary number 1011 to its decimal value.

  1. 11 Correct answer.
  2. 9
  3. 15
  4. 13

Explanation

Reading place values from the left, 1011 equals 1x8 + 0x4 + 1x2 + 1x1, which totals 11. Each position represents a successive power of two.

Question 10Information Technology Fundamentals and Computer Systems

Which memory type is small, extremely fast and located inside the CPU to hold recently used instructions and data?

  1. Virtual memory
  2. Read only memory
  3. Magnetic disk
  4. Cache memory Correct answer.

Explanation

Cache memory sits close to or inside the processor and stores frequently accessed data to reduce the average time to fetch from main memory. Virtual memory is disk-backed, ROM is read-only and disks are secondary storage.

Question 11Information Technology Fundamentals and Computer Systems

A laptop user wants to connect an external monitor and transfer video plus audio through a single cable. Which port type is designed for this?

  1. USB Type-A
  2. RJ-45
  3. HDMI Correct answer.
  4. PS/2

Explanation

HDMI carries both digital video and audio over one cable and is standard for connecting displays. USB Type-A is a general data port, RJ-45 is for Ethernet and PS/2 is a legacy keyboard or mouse connector.

Question 12Information Technology Fundamentals and Computer Systems

Which of the following describes the role of an interpreter during program execution?

  1. It links object files into a single executable
  2. It translates and executes source code one statement at a time Correct answer.
  3. It translates the whole source program into machine code before any line runs
  4. It stores variables permanently on disk

Explanation

An interpreter reads source code statement by statement, translating and executing each in turn, which allows immediate feedback but generally slower execution. A compiler translates the whole program before execution.

Question 13Information Technology Fundamentals and Computer Systems

A user types a website address into a browser. Which service resolves that human-readable domain name into an IP address?

  1. VPN
  2. NAT
  3. DNS Correct answer.
  4. HTTP

Explanation

The Domain Name System maps domain names to IP addresses so clients can reach servers. NAT translates private addresses, VPN creates a secure tunnel and HTTP transfers web content.

Question 14Information Technology Fundamentals and Computer Systems

Which statement correctly distinguishes volatile from non-volatile memory?

  1. Volatile memory keeps data when power is off, while non-volatile loses it
  2. Both types retain data only while the CPU is running
  3. Volatile memory is always read-only, while non-volatile is always writable
  4. Volatile memory loses its contents when power is removed, while non-volatile retains them Correct answer.

Explanation

Volatility refers to whether stored data survives a power loss. RAM is volatile and loses contents on shutdown, whereas ROM, SSDs and hard disks are non-volatile and retain data.

Question 15Information Technology Fundamentals and Computer Systems

In the hexadecimal system, what decimal value does the digit F represent?

  1. 12
  2. 16
  3. 15 Correct answer.
  4. 10

Explanation

Hexadecimal uses sixteen symbols, where A to F stand for decimal 10 to 15. The digit F is the last symbol and equals 15.

Question 16Information Technology Fundamentals and Computer Systems

A technician needs to install an operating system on a new machine. Which component must be functional for the machine to begin the boot process and load the operating system?

  1. The basic input/output system or unified extensible firmware interface Correct answer.
  2. The network printer queue
  3. The graphics card driver
  4. The word processing application

Explanation

Firmware such as BIOS or UEFI runs at power-on, performs hardware checks and locates the bootloader that loads the operating system. Drivers and applications load only after the operating system is running.

Question 17Information Technology Fundamentals and Computer Systems

Which topology connects every device to a single central switch so that a failure of one cable affects only that device?

  1. Star topology Correct answer.
  2. Mesh topology
  3. Ring topology
  4. Bus topology

Explanation

In a star topology each device has its own link to a central switch, so a single cable fault isolates one device. In a bus, one break can disrupt the shared backbone.

Question 18Information Technology Fundamentals and Computer Systems

Which of the following is the primary purpose of an operating system's file management function?

  1. To increase the physical capacity of the hard disk
  2. To compile source code into machine code
  3. To assign IP addresses to network devices
  4. To organise, store, retrieve and control access to files on storage devices Correct answer.

Explanation

File management creates directory structures, tracks where file blocks reside, and enforces access permissions when files are read or written. It organises existing storage rather than enlarging it.

Question 19Information Technology Fundamentals and Computer Systems

A user reports that a computer is running very slowly and the disk activity light stays on almost constantly. Which cause is most consistent with these symptoms?

  1. The monitor resolution is set too high
  2. The keyboard layout is configured incorrectly
  3. The system is heavily using virtual memory because physical RAM is insufficient Correct answer.
  4. The printer driver is out of date

Explanation

When RAM is exhausted, the operating system pages data to disk, causing constant disk activity and severe slowdown. Display, keyboard and printer settings do not produce sustained disk thrashing.

Question 20Information Technology Fundamentals and Computer Systems

Which statement best explains why hexadecimal notation is widely used when working with computers?

  1. It is the only format a processor can execute directly
  2. Each hexadecimal digit corresponds exactly to four binary bits, giving compact representation Correct answer.
  3. It removes the need to convert values to binary
  4. It uses fewer distinct symbols than binary

Explanation

Grouping four binary bits into one hexadecimal digit makes long binary strings shorter and less error-prone to read while preserving exact values. Processors still execute binary machine code.

Question 21Information Technology Fundamentals and Computer Systems

A binary number is shifted left by one position and a zero is appended on the right. What is the arithmetic effect on its value, assuming no overflow?

  1. The value increases by one
  2. The value stays the same
  3. The value is doubled Correct answer.
  4. The value is halved

Explanation

A left shift moves every bit to the next higher place value, which multiplies the number by two, just as appending a zero to a decimal number multiplies it by ten. A right shift performs integer division by two.

Question 22Information Technology Fundamentals and Computer Systems

A delivery team must ensure that a client's data processed at an offshore ITeS centre remains unreadable if intercepted during transmission. Which measure directly addresses this requirement?

  1. Encrypting the data in transit using a secure protocol Correct answer.
  2. Compressing the data before sending
  3. Increasing the network bandwidth
  4. Storing the data in a larger database

Explanation

Encryption transforms data so that intercepted traffic cannot be read without the key, which directly protects confidentiality in transit. Compression, bandwidth and database size affect performance or storage, not confidentiality.

Question 23Information Technology Fundamentals and Computer Systems

A program must store the result of a comparison that can only be true or false. Which data type is most appropriate?

  1. Floating point
  2. Boolean Correct answer.
  3. Integer
  4. String

Explanation

A Boolean holds exactly two logical states, true or false, matching the outcome of a comparison. Integers and floating point hold numbers, and strings hold text.

Question 24Information Technology Fundamentals and Computer Systems

A shared office network slows dramatically whenever a single workstation begins a large file download. Which explanation best fits this behaviour?

  1. The workstation's keyboard has failed
  2. The server's hard disk has been reformatted
  3. The monitor refresh rate has dropped
  4. The workstation is using more than its share of the shared network bandwidth Correct answer.

Explanation

On a shared medium, one host consuming large amounts of bandwidth reduces capacity available to others, causing contention and slowdown. Peripheral faults or display settings do not consume shared network capacity.

Question 25Information Technology Fundamentals and Computer Systems

A technician replaces a failing hard disk with a solid state drive and reinstalls the operating system. Which change in system behaviour is most directly attributable to the new storage device?

  1. Improved keyboard response time
  2. Automatic assignment of IP addresses
  3. Faster application launch and boot times due to lower access latency Correct answer.
  4. Higher monitor resolution being supported

Explanation

An SSD has no moving parts and far lower access latency than a hard disk, so reading the operating system and applications from storage is quicker. Display resolution, addressing and input response are controlled by other subsystems.

Question 26Information Technology Fundamentals and Computer Systems

A payroll application stores each employee's monthly salary in a variable. Which data type should be chosen so that amounts such as 24500.75 are held without losing the fractional part?

  1. Character type
  2. Boolean type
  3. Integer type
  4. Floating-point type Correct answer.

Explanation

A floating-point type is designed to hold numbers that include a fractional part, so values such as 24500.75 are represented with a decimal component. Integer types hold only whole numbers, while character and Boolean types hold text symbols and truth values respectively.

Question 27Information Technology Fundamentals and Computer Systems

A computer lab has 20 workstations that must all share files and a printer without any one machine acting as the central controller. Which network classification fits this arrangement?

  1. Client-server network
  2. Wide area network
  3. Peer-to-peer network Correct answer.
  4. Metropolitan area network

Explanation

In a peer-to-peer network each workstation can act as both a supplier and a consumer of shared resources, so no dedicated central server controls the lab. A client-server design depends on a central server, and WAN and MAN describe geographic reach rather than the sharing model.

Question 28Information Technology Fundamentals and Computer Systems

An ITeS team processes scanned invoices and must convert the printed text into editable digital text automatically. Which technology is designed for this task?

  1. Optical character recognition Correct answer.
  2. Barcode scanning
  3. Disk defragmentation
  4. Voice recognition

Explanation

Optical character recognition analyses the shapes of printed characters in a scanned image and outputs machine-readable text that can be edited or searched. Barcode scanning only decodes encoded symbol patterns, voice recognition works on spoken audio, and defragmentation reorganises files on storage.

Question 29Information Technology Fundamentals and Computer Systems

A spreadsheet cell contains the formula =B2*$C$1. The formula is copied from row 2 down to row 5. Which cell reference appears in the copied formula in row 5?

  1. =B5*$C$4
  2. =B2*$C$4
  3. =B5*$C$1 Correct answer.
  4. =B2*$C$1

Explanation

A relative reference such as B2 shifts by the same number of rows the formula moves, so it becomes B5 after three rows of copying. A reference written with dollar signs on both the column and the row, such as $C$1, is absolute and stays fixed wherever the formula is copied.

Question 30Information Technology Fundamentals and Computer Systems

A company must keep a copy of its customer database at a second site so that operations can resume within hours if the primary data centre is destroyed. Which measure directly satisfies this requirement?

  1. Configuring a redundant array of disks inside the primary server
  2. Installing antivirus software on every database server
  3. Replicating the database in real time to a remote disaster recovery site Correct answer.
  4. Taking a weekly backup onto a tape stored in the same server room

Explanation

Surviving the loss of an entire data centre requires a copy of the data held at a physically separate location, and real-time replication keeps that remote copy current enough for a fast restart. Backups kept in the same room and disk redundancy inside the same server are both lost with that site.

Question 31Office Productivity Software (Word Processing, Spreadsheets, Presentations)

In a word processing document, which feature is used to make a heading appear consistently on every page at the top of the printed output?

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

Explanation

A header is the document area reserved for content repeated at the top of each page, such as chapter titles or page numbers. Footers occupy the bottom margin, while footnotes and endnotes belong to specific text references rather than page margins.

Question 32Office Productivity Software (Word Processing, Spreadsheets, Presentations)

A user wants the first page of a letter to show the organisation logo while later pages show only a page number. Which word-processing setting makes this possible?

  1. Mirror margins
  2. Keep with next paragraph
  3. Different first page header/footer Correct answer.
  4. Widow/orphan control

Explanation

The different-first-page option creates a separate first-page header and footer area, so the logo can appear only on page one while the remaining pages use the default header or footer. The other settings control pagination or margin layout, not header content variation.

Question 33Office Productivity Software (Word Processing, Spreadsheets, Presentations)

In a spreadsheet, a cell displays the value 0.256 when the underlying number is 0.2564 and the cell format is set to two decimal places. What happens to the stored value?

  1. The stored value stays 0.2564; only the display is rounded Correct answer.
  2. The stored value is permanently changed to 0.26
  3. The stored value becomes text "0.256"
  4. The stored value is truncated to 0.25

Explanation

Number formatting in a spreadsheet changes only how a value is displayed, while the underlying stored value retains its full precision. Calculations therefore continue to use 0.2564 rather than the rounded display figure.

Question 34Office Productivity Software (Word Processing, Spreadsheets, Presentations)

Which spreadsheet formula correctly adds the values in cells B2 through B10?

  1. =ADD(B2:B10)
  2. =SUM(B2,B10)
  3. =TOTAL(B2-B10)
  4. =SUM(B2:B10) Correct answer.

Explanation

The SUM function with a colon range such as B2:B10 adds every cell in that contiguous block. A comma between two references would add only those two cells, and a hyphen would subtract them.

Question 35Office Productivity Software (Word Processing, Spreadsheets, Presentations)

A worksheet contains a list of student marks in column C. Which cell reference style must be used so that a formula referring to C2 can be copied down the column and still point to C3, C4 and so on?

  1. Mixed reference such as $C2
  2. Absolute reference such as $C$2
  3. Named range such as Marks
  4. Relative reference such as C2 Correct answer.

Explanation

A relative reference adjusts automatically when the formula is copied, so C2 becomes C3, C4 and so on down the column. Absolute and mixed references lock the column or row and would keep pointing back to the original cell.

Question 36Office Productivity Software (Word Processing, Spreadsheets, Presentations)

A teacher wants a spreadsheet cell to show "Pass" when the mark in A2 is 40 or more and "Fail" otherwise. Which formula achieves this?

  1. =IF(A2>40,"Pass","Fail")
  2. =IF(A2>=40,"Pass","Fail") Correct answer.
  3. =IF("Pass",A2>=40,"Fail")
  4. =IF(A2<=40,"Pass","Fail")

Explanation

The IF function takes a logical test, a value if true and a value if false. Using A2>=40 includes exactly 40 as a pass, matching the stated boundary condition.

Question 37Office Productivity Software (Word Processing, Spreadsheets, Presentations)

Which chart type is most appropriate for showing the percentage contribution of each department to a company's total expenditure?

  1. Histogram
  2. Pie chart Correct answer.
  3. Line chart
  4. Scatter chart

Explanation

A pie chart divides a single whole into proportional slices, which directly communicates each department's share of total expenditure. Line and scatter charts show trends or relationships between variables, and a histogram shows the distribution of one numeric variable.

Question 38Office Productivity Software (Word Processing, Spreadsheets, Presentations)

In a presentation program, what is the purpose of the slide master?

  1. To store the common layout, fonts and background applied to slides Correct answer.
  2. To convert the presentation into a PDF file
  3. To store the animation timeline for one slide only
  4. To record the speaker's notes for each slide

Explanation

The slide master holds the design elements shared across slides, such as placeholder positions, fonts, colours and background, so edits there propagate to all slides using it. Speaker notes, per-slide animation and export settings are handled elsewhere.

Question 39Office Productivity Software (Word Processing, Spreadsheets, Presentations)

A presenter wants each bullet point on a slide to appear one at a time when the mouse is clicked during the slideshow. Which feature should be configured?

  1. Hide slide
  2. Rehearse timings
  3. Slide transition with automatic timing
  4. Custom animation with an on-click start trigger Correct answer.

Explanation

Custom animation applied to individual bullet items, with the start set to on click, reveals each point only when the presenter advances. Transitions affect the change between whole slides, and rehearsal timings record automatic advance intervals.

Question 40Office Productivity Software (Word Processing, Spreadsheets, Presentations)

Which file format is most suitable for sharing a presentation that must open with its exact layout on a computer without presentation software installed?

  1. TXT
  2. PDF Correct answer.
  3. CSV
  4. PPTX

Explanation

A PDF preserves the visual layout and can be opened with a free universal reader on almost any system. The native PPTX format requires compatible presentation software, and TXT or CSV cannot retain slide design.

Question 41Office Productivity Software (Word Processing, Spreadsheets, Presentations)

A user needs to insert the same paragraph of standard terms at the end of many different documents. Which feature avoids retyping it each time?

  1. Thesaurus
  2. Track changes
  3. Spell check
  4. AutoText or a reusable building block Correct answer.

Explanation

AutoText and building blocks store reusable chunks of content that can be inserted into any document on demand. Spell check, track changes and the thesaurus serve proofing and review purposes and do not store reusable text.

Question 42Office Productivity Software (Word Processing, Spreadsheets, Presentations)

In a word processor, what does the Find and Replace feature with the "Match case" option enabled do?

  1. It replaces only text in headers and footers
  2. It replaces only occurrences with identical capitalisation Correct answer.
  3. It replaces only whole words but ignores case
  4. It replaces every occurrence regardless of case

Explanation

Match case restricts searching and replacing to text whose uppercase and lowercase letters exactly match the search term. Without it, the tool treats upper and lower case letters as equivalent.

Question 43Office Productivity Software (Word Processing, Spreadsheets, Presentations)

A spreadsheet contains a long list of sales records, and the user wants to display only records where the region is "North". Which feature should be used?

  1. Freeze panes
  2. Conditional formatting
  3. AutoFilter Correct answer.
  4. Data validation

Explanation

AutoFilter adds drop-down controls to column headings so that rows matching a chosen criterion are shown and the rest are hidden. Freeze panes, conditional formatting and data validation change visibility or appearance but do not filter rows by value.

Question 44Office Productivity Software (Word Processing, Spreadsheets, Presentations)

Which spreadsheet function counts the number of cells in range D2:D50 that contain numeric values only?

  1. =COUNTBLANK(D2:D50)
  2. =COUNT(D2:D50) Correct answer.
  3. =SUM(D2:D50)
  4. =COUNTA(D2:D50)

Explanation

COUNT tallies only cells containing numbers, ignoring text and blanks. COUNTA counts all non-empty cells, SUM adds the values, and COUNTBLANK counts empty cells.

Question 45Office Productivity Software (Word Processing, Spreadsheets, Presentations)

A user wants the row of column headings to remain visible while scrolling through a large worksheet. Which feature is designed for this?

  1. Freeze panes Correct answer.
  2. Wrap text
  3. Merge cells
  4. Split cells

Explanation

Freeze panes locks specified rows or columns in place so they stay visible as the user scrolls through the rest of the sheet. Merging, splitting and wrapping affect cell content and layout rather than scroll visibility.

Question 46Office Productivity Software (Word Processing, Spreadsheets, Presentations)

In a presentation, a chart pasted with a link to the source spreadsheet is edited in the spreadsheet. What happens to the chart in the presentation?

  1. It converts automatically into a table
  2. It is deleted from the slide
  3. It remains unchanged until pasted again as a picture
  4. It updates to reflect the changed spreadsheet data Correct answer.

Explanation

A linked chart maintains a connection to its source data, so changes made in the spreadsheet are reflected in the presentation. An unlinked chart pasted as a picture would not update.

Question 47Office Productivity Software (Word Processing, Spreadsheets, Presentations)

Which word-processing feature is used to add a numbered citation reference in the body text that corresponds to an entry at the bottom of the same page?

  1. Insert bookmark
  2. Insert hyperlink
  3. Insert comment
  4. Insert footnote Correct answer.

Explanation

A footnote places a reference marker in the text and the corresponding note at the bottom of the same page. Comments are review remarks, bookmarks mark locations and hyperlinks navigate to other content.

Question 48Office Productivity Software (Word Processing, Spreadsheets, Presentations)

A user applies the Heading 1 style to chapter titles. What is the main benefit for navigation and document structure?

  1. The titles are converted into footnotes
  2. The titles are locked against editing
  3. The titles appear in the navigation pane and automatic table of contents Correct answer.
  4. The titles are automatically spell-checked

Explanation

Applying built-in heading styles marks text as structural headings, which the navigation pane and automatic table of contents use to build an outline. Styles do not lock text, trigger spell check or convert text into footnotes.

Question 49Office Productivity Software (Word Processing, Spreadsheets, Presentations)

In a spreadsheet, which operator has the highest precedence in the formula =2+3*4^2?

  1. All operators are evaluated left to right
  2. Exponentiation (^) Correct answer.
  3. Multiplication (*)
  4. Addition (+)

Explanation

Spreadsheet formulas follow standard mathematical precedence: exponentiation first, then multiplication and division, then addition and subtraction. The expression therefore evaluates 4^2 first, then multiplies by 3, then adds 2.

Question 50Office Productivity Software (Word Processing, Spreadsheets, Presentations)

A user wants to ensure that only dates are entered into a column of a worksheet. Which feature should be configured?

  1. Goal seek
  2. Pivot table
  3. Data validation Correct answer.
  4. Conditional formatting

Explanation

Data validation restricts the type and range of values that can be entered into a cell, so a date rule will reject non-date input. Conditional formatting only changes appearance, pivot tables summarise data and goal seek adjusts inputs to reach a target.
