1 Question 1 of 10

An event organiser at an exhibition centre in Malkerns issues entry tickets. What design trait makes QR codes superior to 1D barcodes for ticket validation?

A QR codes can generate an audible chime directly from the paper ticket surface when held near an attendee's ear channel. B QR codes can be scanned reliably from various angles, and error correction allows them to work even if the ticket gets slightly smudged. C QR codes automatically encrypt the user's personal banking password into the image pattern when printed from a household printer. D QR codes change their physical printed colour dynamically over time to indicate whether the gate ticket has expired.

2 Question 2 of 10

When an expert system is used to diagnose a complex fault in a car engine at a workshop in Matsapha, what is the primary purpose of the explanation system?

A To allow the mechanic to input new mechanical engineering rules directly into the engine database without using keyboard hardware. B To translate the mechanical error messages into multiple different international languages automatically using web-based translation tools. C To prevent the system from displaying incorrect solutions if the user accidental enters conflicting facts during data capture stages. D To show the user step-by-step logic and reasons why specific engine faults were suggested as the final solutions.

3 Question 3 of 10

Match the communication feature to its correct application: Which feature describes a characteristic true of video calls but not true of standard VoIP audio calls?

A It converts acoustic voice vibrations into digital binary data packets. B It requires a stable internet protocol connection to establish a link. C It necessitates continuous compression of real-time visual frames. D It allows two or more individuals to converse synchronously online.

4 Question 4 of 10

Which scenario illustrates a vulnerability associated with the use of contactless RFID payment cards or Near Field Communication devices?

A An unauthorized reader hidden close by could intercept unencrypted card signals to skim financial credentials. B Strong cellular network towers can permanently erase all stored data files from an RFID card's internal memory bank. C The card chip might overheat and catch fire if it is scanned more than three times within a single business day. D The card data cannot be read at all if there are multiple standard paper labels attached to the same product box.

5 Question 5 of 10

Which hardware component produces the images that are sent to a monitor?

A Sound card B Network Interface Card (NIC) C Random access memory (RAM) D Graphics card

6 Question 6 of 10

Which input device is mainly used to enter text and numbers by pressing keys?

A Light pen B Keyboard C Scanner D Joystick

7 Question 7 of 10

Which sequence correctly shows how data moves through a computer system?

A Input, then processing by the CPU, then output B Output, then processing by the CPU, then input C Processing by the CPU, then input, then output D Input, then output, then processing by the CPU

8 Question 8 of 10

Which statement accurately describes a core characteristic of Radio Frequency Identification Device (RFID) systems?

A It requires a direct optical line of sight between the tracking tag and the reader device to process data. B It uses radio waves to transmit data wirelessly between a tracking tag and a reading apparatus without contact. C It relies on manual physical swiping of a magnetic strip through a dedicated slot to update terminal records. D It translates physical black and white parallel lines into text data using an optical laser scanning mechanism.

9 Question 9 of 10

A secondary school matches its student data structure across different systems. Which pair correctly links the system with its typical performance data metric?

A Library Database: Records the total number of minutes a student spends typing an essay during an evening ICT lesson. B Biometric System: Tracks the percentage accuracy achieved by a student when completing a physics multiple-choice module. C Computer Aided Learning: Stores individual module completion percentages and automated quiz scores for review by staff. D Attendance Register: Tallies the precise breakdown of marks awarded for a physical education practical gymnastics assessment.

10 Question 10 of 10

Which is a similarity between an intranet and an extranet?

A Both are open to anyone in the world B Both are public networks C Neither can use the internet D Both are private networks that restrict who can access them
