Introduction to ICT and its role in daily life

Correct answer: C. When it meets user needs safely, accessibly and effectively

Explanation: The governing concept is user-centred evaluation of ICT. A solution is successful when it solves a genuine problem and can be used safely, reliably and effectively by the intended people, including users with different abilities or access conditions. Therefore, option C is correct. High price and novelty are not proof of value, while a large number of unused features can make a system confusing rather than useful.

Correct answer: D. The service did not account for users with low network capacity

Explanation: The governing concept is inclusive and context-sensitive ICT design. A service intended for broad public use should consider slow networks, limited data, shared devices and other local conditions. If it functions only with fast internet, its design has failed to support users with low bandwidth, so option D is correct. Colour choice does not explain the access barrier, and the other statements are unsupported or overly general.

Correct answer: A. It improves speed, access and collaboration, but requires safe use, skills and reliable information.

Explanation: ICT includes digital tools used to create, store, process and communicate information. It can improve speed, access, learning and collaboration, but its benefits depend on digital skills, privacy, security and reliable information. Therefore, option A is balanced because it recognises both advantages and responsible-use conditions. Options B, C and D make absolute claims that ignore human judgement, wider uses and the continued value of traditional methods.

Correct answer: B. Collecting, processing, storing, communicating and applying data to useful decisions.

Explanation: An ICT system is useful when it handles information through connected stages rather than performing only one isolated action. Data may be collected, processed into meaningful information, stored for later use, communicated to people and applied to decisions or actions. Option B contains this complete functional sequence. The other choices describe starting a device, limited messaging or unnecessary replacement, not an information cycle.

Correct answer: B. Digital divide.

Explanation: The digital divide is the gap between people who can access and effectively use digital technologies and those who cannot. In this case, unstable internet prevents some students from participating equally in online lessons, so option B is correct. A processing problem concerns handling data, a software error concerns faulty programs, and information overload means receiving too much information; none explains unequal access.

Correct answer: C. A farmer chooses an unsuitable sowing time because of incorrect weather data.

Explanation: The quality of a decision depends partly on the accuracy, timeliness and relevance of the information used to make it. If weather data are incorrect, a farmer may select the wrong sowing time and suffer avoidable loss. Therefore, option C demonstrates a direct data-quality effect. The other options concern document appearance, naming or hardware operation and do not show an information-based decision being distorted.

Correct answer: D. The user has received view-only permission.

Explanation: Cloud services control what a person can do through access permissions. A user with view-only or read-only permission can open and inspect a file but cannot change its contents; an owner or editor must grant editing rights. Thus option D is correct. A file name, a small file size and a monitor state do not normally determine whether the account is authorised to edit the cloud file.

Correct answer: A. To link the correct record with the correct patient.

Explanation: A patient identification number acts as a unique or controlled identifier in a digital health-record system. It helps staff retrieve the correct medical history, test results and prescriptions while reducing the risk of confusing records belonging to different patients. Option A is therefore correct. It does not make a name public, alter report colours or replace professional medical judgement, so B, C and D are unsuitable.

Correct answer: B. When an unverified message has been shared many times.

Explanation: Popularity measures how widely content is circulated, not whether the claim is accurate. An unverified message can become viral because it is emotional, surprising or repeatedly forwarded, while still lacking evidence. Option B therefore shows why popularity fails to prove reliability. Official support, independent confirmation, and identifiable authorship or dates provide stronger checks, although each should still be evaluated critically.

Correct answer: D. The person making changes and earlier versions can be traced.

Explanation: Version history records earlier states of a document and may show which collaborator made particular changes and when. This supports accountability, helps identify mistakes and often allows an earlier version to be restored. Option D is correct because it captures both change tracking and access to previous versions. It does not automatically reduce file size, improve internet speed or make a private document public.

Correct answer: A. Mobile banking provides service from home but creates a phishing risk

Explanation: The governing concept is that ICT can improve access and convenience while introducing new digital risks. Mobile banking lets a customer use banking services without travelling to a branch, so access increases. However, fake messages or websites may steal login details through phishing. Therefore, option A correctly presents both the benefit and the security challenge; the other options do not show this combination.

Correct answer: B. Because incorrect input, the data-entry process, or user error may also be responsible

Explanation: The governing concept is the input-process-output model. A wrong result may come from incorrect or incomplete input, a data-entry mistake, an unsuitable instruction, faulty processing, hardware trouble, or user error—not only from the software. Option B is correct because it identifies several possible causes. Option A is false because software can contain bugs, while C and D contradict how digital systems work.

Correct answer: C. When hands-on practice with physical laboratory equipment is necessary

Explanation: The governing concept is that ICT improves communication but cannot reproduce every physical experience. Video conferencing can deliver short updates, share screens, and connect people in different cities. It cannot provide the same direct handling, movement, safety practice, or sensory feedback as working with laboratory equipment. Therefore, option C is correct; the other situations are strengths or normal uses of video conferencing.

Correct answer: D. Only an authorised person can view private records after verification

Explanation: The governing concept is authentication: a system checks identity before granting access. Option D protects privacy because personal records are not exposed to everyone, and it improves security because only an authorised, verified person can view them. Options A, B, and C weaken protection by exposing passwords, removing individual accountability, or allowing access without identity checks. Thus D is the only complete example.

Correct answer: A. The system changes practice difficulty according to student performance

Explanation: The governing concept is personalised or adaptive learning, in which digital content responds to an individual learner’s needs and performance. Option A is correct because the system changes practice difficulty using evidence about that student’s progress. The other choices either provide unsuitable material, remove interaction, or delete learning resources; none adapts instruction to the learner. Personalisation means purposeful adjustment, not merely using a digital device.

Correct answer: B. Because records can be recovered if a device fails or data is deleted

Explanation: The governing concept is data protection through backup and recovery. A separate copy allows a record to be restored after accidental deletion, device failure, corruption, theft, or another loss event. Option B correctly explains this practical value. A is not necessarily true, while C describes exposure rather than protection and D confuses storage with network performance. A backup is useful only when it is stored safely and can be recovered.

Correct answer: C. A teacher checks unusual results after automated mark calculation

Explanation: The governing concept is human oversight of automation. Automated mark calculation can process many entries quickly, but incorrect data, unusual values, or a programming problem may still produce an unreliable result. In option C, the teacher uses automation for speed and reviews exceptions for accuracy and fairness. Option D removes necessary checking, while A and B do not demonstrate meaningful automation or review.

Correct answer: D. Violation of privacy and data ethics

Explanation: The governing concept is informed consent and responsible data use. Personal information should be collected and used for a clear, legitimate purpose that the user understands and agrees to. Reusing it without consent violates privacy and weakens trust, so option D is correct. Reduced productivity, the digital divide, and screen fatigue are different concerns and do not describe unauthorised secondary use of personal data.

Correct answer: A. Remote meetings reduce unnecessary travel and fuel use

Explanation: The governing concept is an indirect environmental benefit of ICT. Remote meetings replace some journeys, which can reduce fuel consumption, traffic, and associated emissions when travel would otherwise be necessary. Thus option A is correct. Discarding devices creates e-waste, leaving screens on wastes electricity, and printing many copies consumes paper and energy; these choices do not show conservation.

Correct answer: B. When the user receives excessive unorganised and conflicting information

Explanation: The governing concept is information overload: receiving more material than a person can efficiently evaluate, especially when it is disorganised or contradictory. Option B is correct because the user may struggle to identify reliable facts, compare alternatives, and decide confidently. Necessary verified facts, a clear summary, and organised sources reduce cognitive burden rather than create overload. The problem is not simply having information, but having too much of poor structure or uncertain relevance.

Correct answer: C. Decision quality depends on updated data

Explanation: The governing concept is that an ICT system depends on the quality and freshness of its data. A map may calculate the shortest route correctly from its stored information, yet a recently closed road makes that information incomplete or outdated. Therefore, option C is correct. Options A, B, and D are overgeneralised: digital maps are not always useless, location data is not always wrong, and paper maps are not automatically better.

Correct answer: D. Lack of inclusion and support for diverse learning needs

Explanation: The governing concept is inclusive and accessible ICT. A school system should accommodate different learning speeds, abilities, and support requirements through clear instructions, adjustable pace, accessibility features, or teacher assistance. If only fast learners benefit, the system excludes other students; therefore, option D is correct. The colours, number of computers, and teachers’ use of tools do not directly identify this inclusion problem.

Correct answer: A. A farmer uses weather forecasts along with local soil conditions and past experience

Explanation: The governing concept is that ICT supports human judgement rather than automatically replacing it. In option A, the farmer checks a weather forecast, which is digital information, and combines it with local soil conditions and past experience before deciding. That comparison improves reliability and relevance. B relies on one unverified source, while C and D reject useful information, so A is the only balanced example.

Correct answer: B. It becomes difficult to identify who performed an action

Explanation: The governing concept is the connection between digital identity and accountability. With separate accounts, a system can normally associate a change, deletion, or upload with the responsible user. A shared account hides that identity, so investigating an error or misuse becomes difficult; option B is correct. Sharing does not make an account faster, guarantee file security, or make users equally skilled.

Correct answer: C. When members repeatedly erase one another's changes without coordination

Explanation: The governing concept is that effective ICT collaboration requires coordination, role clarity, and controlled editing. If members repeatedly overwrite or erase one another’s work without communicating, useful content can disappear, conflicts can arise, and the final document can become inconsistent. Therefore, option C describes the harmful situation. Clear roles, version history, and controlled permissions generally help preserve quality rather than reduce it.
