Introduction to ICT and its role in daily life

Captions represent spoken words as written text, allowing a learner with hearing impairment to understand information in a video. This shows how ICT can remove barriers and support equal participation in education and communication. Option A is correct because it expresses accessibility and inclusion together. Captions are not data theft, merely entertainment, or a hardware-repair activity.

The governing concept is inclusive access to ICT-enabled communication. A school should use more than one channel so that families without smartphones can still receive timely and understandable notices. SMS, printed notices, telephone calls or a notice board can supplement the application. Ignoring those parents, forcing one technology or stopping communication increases exclusion rather than solving the access barrier.

The governing concept is responsible sharing of personal information online. A public address reveals where a person may live, while a daily schedule can reveal when the home may be empty or when the person can be located. Together they increase privacy and physical-safety risks. Such posts do not strengthen a password, secure an account or improve network speed, so option A is the only valid evaluation.

The governing concept is backup and risk management. A backup is a separate copy of important data stored in another safe location, such as an encrypted external device or a trusted cloud service. If the original phone fails, the family can recover the documents from that copy. Renaming the phone or reducing brightness does not protect files, while deleting images causes further loss. Therefore option D is correct.

The governing concept is automation: using software to perform a repetitive, rule-based task with little manual effort. Automatically calculating a bill total and tax saves time, produces consistent results and can reduce arithmetic errors, thereby improving efficiency. Options A and C repeat work manually, while B makes file management poorer. Automation supports human work; it does not mean that every decision must be surrendered to a machine.

The governing concept is the speed and reach of digital information. A digital notice can be edited quickly and shown to many viewers through connected screens or systems, so option A is correct. However, staff must still check accuracy before publishing. Option B is false because students must read the notice; C is false because digital errors remain possible; and D is false because electronic displays need power.

The governing concept is resource sharing through a computer network. When computers are connected, they can access a common peripheral such as a printer instead of requiring one printer for each machine. Therefore, option B is correct. Option A describes isolation, which prevents sharing; option C concerns deletion rather than connectivity; and option D is too narrow and unrelated to the stated office use.

The governing concept is password security through unpredictability. A name and birth year are often available to classmates, acquaintances, or through public profiles, so attackers can try them easily. Option B is correct. A safer password should be long, unique, and difficult to predict, ideally using a mixture of character types and protected by multi-factor authentication where available. Length alone or the presence of letters does not guarantee safety.

The governing concept is accessibility through assistive technology. A screen reader converts on-screen text into spoken output, allowing a visually impaired user to access information and navigate digital content. Therefore, option C directly removes a visual barrier. Reducing image size does not provide access by itself, while printed-only text and removing the keyboard can make access more difficult.

The governing concept is balanced ICT use and its effect on social relationships. Technology can connect distant people, support teamwork, and deliver urgent messages, but excessive device use may replace meaningful face-to-face conversation and shared time. Thus, option D describes the harmful situation. The other examples use ICT to strengthen communication or cooperation rather than to avoid personal interaction.

Automation means using a programmed system, software, or machine to perform a defined and often repetitive task with less direct human intervention. Option A is correct because it includes both technology and rule-based work. Automation may improve speed and consistency, but it does not eliminate every human decision; people still design, monitor, and review systems. It is also broader than making devices or merely saving electricity.

Two-step verification strengthens authentication by requiring two separate forms of evidence, commonly something the user knows, such as a password, and something the user has or receives, such as a device code. Option A is correct because the extra identity check makes unauthorised access harder even if a password is exposed. It does not increase transaction value, publish account details, or intentionally slow the website.

The governing concept is data integration: combining information from different systems so it can be viewed and used together. If the systems use incompatible formats or identifiers, records cannot be joined easily, so preparing one complete student report becomes difficult and may require manual conversion. Therefore, option C is correct. Option B is opposite to the situation, while A and D do not follow from incompatibility.

The governing concept is responsible use of ICT services and transaction verification. A payment display may show a pending, failed, or delayed settlement, so the user should first record the transaction reference and check the bank or payment-service status. Option D is correct because it helps confirm whether money was debited and supports a formal complaint. Repeating payment may cause duplication; blaming someone or abandoning digital payments is unjustified.

The governing concept is personalised or adaptive learning. Such a platform uses information about a learner’s pace or responses to select suitably paced or challenging questions. This can support different learning needs instead of forcing every student through exactly the same sequence. Therefore, option A is correct. Option B describes uniform learning, C is an unrelated and excessive claim, and D states only a possible data function rather than the benefit described.

The governing concept is data currency, meaning that information-based ICT services depend on current and accurate inputs. A map can calculate a route correctly from the data it has, yet still mislead a traveller when a recent road closure is missing. Therefore, option B is correct. Option A is false because maps contain data, C is an unjustified generalisation, and D ignores the purpose of route planning.

The governing concept is that ICT improves efficiency only when the system fits the task and users can operate it. A complex system introduced without training may create errors, delays, repeated work and dependence on technical help, so the expected benefit is lost. Option C is correct. Options A, B and D describe conditions that generally support efficient use rather than reduce it.

The governing concept is effective communication: information must be accurate, understandable and timely. A disaster warning is meant to support immediate action, such as evacuation or seeking shelter. If it arrives after the danger has passed or action is no longer possible, its practical value is greatly reduced even when its content is correct. Therefore, option D is correct; A and C are absolute false claims, while B is not essential.

The governing concept is the sensor-data-response cycle. A sensor detects a condition such as temperature, light, motion or moisture and converts it into data. The smart system then processes that information and may trigger an action, such as switching a device on or sending an alert. Thus option A is correct. Printing is not essential, and the system neither works without data nor removes every human responsibility.

The governing concept is information retrieval. A digital document can scan its stored text for a chosen word, phrase or identifier and locate matching places much faster than manually checking many paper pages. Therefore, option B correctly identifies the benefit. Search does not guarantee that the document is accurate, does not automatically grant editing permission, and does not remove the need to store the file.

The governing concept is digital information literacy: popularity and truth are different properties. Thousands of shares show that content circulated widely, but people may share material without checking it, and false or misleading claims can spread quickly. Option C is correct because verification requires a credible source, supporting evidence and, where possible, comparison with reliable reporting. Options A and B trust popularity blindly, while D is an equally unjustified absolute claim.

The governing concept is dependence of connected ICT services on network connectivity. Remote commands and current device information usually travel through the home network or internet, so a failure can prevent control, status updates or notifications even though the physical devices are not destroyed. Therefore, option D is correct. Options A, B and C claim effects that do not normally follow from a network outage.

The governing concept is the use of ICT to collect and process real-time information. A transport application combines the vehicle’s location, current speed, route, traffic conditions and sometimes historical travel patterns to estimate the remaining journey time. Therefore, option C is correct. Vehicle colour and passenger age do not calculate travel duration, while an estimate without data would have no reliable basis.

The governing concept is traceability in digital records. A timestamp stores the date and time associated with an entry or modification, helping users arrange events chronologically, review activity, and investigate errors or disputes. Therefore, option B is correct. A timestamp does not choose a file’s colour, reveal a password, or shut down the internet; those options confuse record metadata with unrelated functions.

The governing concept is the role of operating-system interface elements. The taskbar normally displays buttons or indicators for open and minimized programs and helps the user switch between them, so option D is correct. A title bar identifies one window, a scroll bar moves through content, and a menu bar contains commands rather than a list of open programs.
