Introduction to ICT and its role in daily life

The governing concept is visual bias through selective presentation. A communicator can influence interpretation not only by changing numbers but also by deciding which evidence is prominent, large, or easy to notice. Option A is correct because supporting data are emphasised while contrary evidence is minimised. That practice is not complete neutrality; it does not prove that the scale is appropriate or that the design is accessible.

The governing concept is decision support: ICT becomes more than a display tool when data is processed and interpreted to guide a choice. In A, the farmer analyses weather and market data and then selects a suitable selling time. B only displays an image, C opens an unused document, and D performs a system operation without supporting a decision.

The governing concept is efficient digital information retrieval. A properly organised electronic record system allows hospital staff to locate an older report quickly when it is needed for care or reference. Therefore B is correct. Entertainment is unrelated, the situation involves finding existing data rather than creating it, and digital retrieval generally reduces unnecessary paperwork instead of increasing it.

The governing concept is the difference between raw data and meaningful information. Individual marks are raw data; calculating their average and using it to describe class performance processes those data into an interpretable result. Thus C is correct. A only records unsorted values, B creates an empty structure, and D changes a file label without analysing the marks or producing meaning.

A communication tool mainly carries messages, whereas a strategic resource helps an organisation understand conditions and choose better actions. Analysing digital data can reveal trends, demand, risks and performance, which supports planning and evidence-based decisions. Thus option A is correct. Email, typing and unrevised storage may support routine work, but they do not by themselves create strategic insight or direction.

An automated banking system can compare transaction details such as amount, location, timing and frequency with expected patterns. Unusual combinations may be flagged for review because they indicate possible fraud or other risk. Thus option C describes the central ICT role: processing and analysing data to identify patterns and support decisions. Storage, messaging and receipt printing may occur, but they do not perform the key detection task.

The governing concept is the filter-bubble effect created by personalised content systems. When an online platform repeatedly selects material similar to past preferences, the user may see fewer opposing or unfamiliar viewpoints and may develop a narrow understanding. Option D is correct. Personalisation does not guarantee verification, does not remove privacy risks, and certainly does not provide every possible perspective.

The governing concept is user autonomy, meaning that people should understand important choices and retain meaningful control over them. Convenience becomes harmful when an application makes significant decisions automatically without clear consent, explanation, or an opportunity to change the result. Option C is correct. Understanding choices, clear settings, and the ability to reverse a decision all support autonomy rather than reduce it.

A mature evaluation recognises both the benefits and the conditions that shape ICT outcomes. Digital tools can improve access, speed, communication, learning, and efficiency, but unequal access, unreliable data, privacy risks, cyber threats, unethical design, or careless behaviour can reduce or harm those benefits. Option B is balanced and evidence-aware. A is exaggerated, while C and D ignore ICT’s social and practical effects.

Overall performance is limited by the slowest important part of the workload, not by the processor alone. If RAM is very low, the system may constantly move data to storage; if that storage is also slow, this bottleneck remains even after a CPU upgrade. Option C is therefore correct. A clean screen, new mouse, or muted speakers has no meaningful effect on processing speed.
