Introduction to ICT and its role in daily life

Correct answer: A. Sharing resources and information between devices

Explanation: A computer network connects devices so that authorised users can communicate and share resources such as files, printers, applications, or data. A network does not mean that every computer is isolated, nor does it always remove the need for internet access. Deleting all files is not a benefit and could cause loss. Therefore, resource and information sharing in option A is correct.

Correct answer: A. Digital information access

Explanation: A school website publishes information in digital form, and viewing its timetable means retrieving that information through a connected device. The user can consult an updated schedule without relying only on a paper notice or oral message. Mechanical repair and paper storage describe different activities. Hence, accessing a timetable online is an example of digital information access, as stated in option A.

Correct answer: A. By automating repetitive tasks

Explanation: ICT improves efficiency by automating repetitive activities such as calculations, data entry, scheduling and routine report generation. Software can perform these steps quickly and consistently, allowing people to spend more time on tasks that need judgement or creativity. Therefore, option A is correct. Adding unnecessary steps, recording everything only by hand and stopping communication generally waste time and reduce coordination rather than improving efficiency.

Correct answer: A. Organising events and reminders

Explanation: A digital calendar records dates and appointments and can provide reminders for classes, meetings, examinations, birthdays, or tasks. It supports planning and time management by presenting events in an organised form. It does not cool a computer, edit image quality, or manufacture a screen. Therefore, organising events and reminders is the correct daily-life use in option A.

Correct answer: A. Send it as an email attachment

Explanation: An email attachment is a file included with an email message, allowing the recipient to download or open a copy of the document. The sender should select the intended file and verify the recipient before sending. Turning off the computer, remembering a filename, or leaving a document displayed does not transfer the file. Therefore, option A is the direct method.

Correct answer: A. Customer communication and information updates

Explanation: The company uses a digital messaging system to communicate useful, timely information about an order, such as confirmation, dispatch, or delivery status. This improves customer communication and keeps the customer informed. It does not alter the product’s physical weight or office size, and digital messages do not necessarily eliminate human contact. Thus, option A describes the ICT role.

Correct answer: A. Access to learning material even from a distant location

Explanation: Online education can provide lessons, recorded material, assignments, and classes to learners who are away from a school or unable to attend in person, provided they have suitable access and support. It does not guarantee marks without effort, remove the value of teachers, or remove cybersecurity responsibilities. Accessibility and flexibility make option A the valid benefit.

Correct answer: A. Image editing software

Explanation: Image-editing software is designed to change digital photographs by cropping, resizing, adjusting brightness or colour, and sometimes adding or removing elements. A spreadsheet is mainly used for tabular data and calculations, while a musical instrument and paper cutter are not software at all. The task is therefore matched directly with image-editing software in option A.

Correct answer: A. Listening to music online

Explanation: Listening to music through an online service uses a digital device, software, and a communication network to deliver entertainment content. The other examples may be useful manual activities, but they do not use ICT in the described form. Online music therefore demonstrates how ICT supports entertainment, while the alternatives are unrelated to digital media. Option A is the only suitable answer.

Correct answer: A. Polite and responsible behaviour online

Explanation: Netiquette is the set of courteous and responsible practices used when communicating online. It includes using respectful language, avoiding harassment, checking information before forwarding it, respecting privacy, and considering that messages can affect real people. Measuring speed and repairing a computer are technical tasks, while sharing passwords is unsafe. Hence, option A correctly defines netiquette.

Correct answer: C. Limiting private details through privacy settings

Explanation: Privacy settings can limit who may view personal details, reducing unnecessary exposure of information such as an address, phone number, or profile data. A person should still share carefully because settings are not a complete guarantee. Publishing an address, sending a password to a stranger, or reusing a simple password increases risk. Therefore, option C best protects personal information.

Correct answer: A. It has enabled news to be received quickly through digital media

Explanation: ICT enables news organisations and individuals to publish and receive updates through websites, applications, social platforms, and digital broadcasts. This can increase speed and reach, although readers still need to check sources because online information may be inaccurate or biased. ICT has not eliminated news or limited it to print. Therefore, option A gives the correct broad change.

Correct answer: A. Scanner

Explanation: A scanner captures the text or image on a paper document and converts it into a digital image or file that a computer can store and process. A speaker produces sound, a projector displays visual output, and a mouse pad supports mouse movement. These devices may be used with a computer but do not digitise a paper document. Therefore, option A is correct.

Correct answer: A. To display digital content on a large screen

Explanation: A projector receives visual output from a computer or another source and enlarges it onto a wall or screen so that a class can view slides, images, videos, or diagrams together. It is an output and display device, not a voice recorder or permanent storage device. Password creation is a software or security task. Thus, option A correctly states its school use.

Correct answer: A. Check the secure connection and seller details

Explanation: A shopper should inspect the website address and secure connection, review identifiable seller and contact details, and consider independent reviews and clear return policies. A secure connection alone does not prove that a seller is honest, but checking it together with seller information is a useful precaution. Colourful advertisements, unusually low prices, and unknown requests for bank details can indicate risk. Option A is best.

Correct answer: A. Names and contact details of people

Explanation: A mobile contact list is a digital collection of people’s names and details such as phone numbers, email addresses, or labels. It helps the user find and communicate with saved contacts quickly. The colours of pictures are image data, weather control is not a type of stored contact information, and physical weight is a property of the device. Therefore, A is correct.

Correct answer: A. To quickly send warnings and relief information

Explanation: During a disaster, communication networks, alerts, websites, and mobile applications can distribute warnings, evacuation instructions, shelter locations, and requests for help quickly to many people. ICT cannot guarantee that every disaster will be prevented, and switching off all devices would reduce access to vital information. Entertainment messages are not the priority. Therefore, option A describes the useful role.

Correct answer: A. Online collaboration

Explanation: An online shared document allows several authorised users to view, comment on, or edit the same file, often from different places. This supports communication, division of work, and teamwork, so it is called online collaboration. Personal storage only keeps files for one user, printing creates a physical copy, and mechanical calculation is a different activity. Therefore, option A is correct.

Correct answer: A. Difference in access to digital devices and internet among people

Explanation: The digital divide is the gap between people or communities that have reliable access to digital devices, internet connectivity, skills, and useful online services and those that do not. It can affect education, work, healthcare, and government services. Splitting a screen or copying a file uses digital tools but does not describe this social inequality. Thus, option A is correct.

Correct answer: A. Increased screen time affecting health and routine

Explanation: Long or poorly managed screen use may contribute to eye strain, reduced physical activity, disturbed sleep, poor posture, or disruption of study and daily routines. Effects depend on the person and habits, so balanced use, breaks, suitable posture, and healthy offline activities are important. Excessive ICT use does not make knowledge disappear, change paper weight, or remove the need for internet. Hence, A is correct.

Correct answer: A. To recover information if the original file is lost or damaged

Explanation: A backup is an additional copy of data kept separately from the working copy. If the original is accidentally deleted, corrupted, lost, or affected by device failure, the backup can help restore the information. It is useful only when made and maintained properly, and important backups should be protected. It does not alter a file’s meaning, increase weight, or slow the internet. Option A is correct.

Correct answer: A. Viewing and paying an electricity bill through a mobile application

Explanation: A mobile billing application uses ICT to display the amount due, provide payment choices, record the transaction, and sometimes offer a receipt. This helps a household manage a regular responsibility from a convenient location, though users should verify the recipient and protect payment credentials. The other options are manual household activities rather than ICT-based management. Therefore, A is correct.

Correct answer: A. To explain a topic using slides with text and images

Explanation: Presentation software is used to create and arrange slides containing text, images, charts, audio, or video so that a topic can be explained to an audience. A spreadsheet is generally more suitable for calculating averages, replacing hardware is a physical maintenance task, and disconnecting the internet is a network action. Therefore, the slide-based explanation in option A matches the software’s purpose.

Correct answer: A. When a short immediate response is needed

Explanation: Instant messaging is designed for quick, usually short exchanges and may show delivery or typing status, making it useful when an immediate reply is expected. A formal, detailed application is often better organised and documented through email or another official channel. Both services normally require connectivity, and neither is suitable when digital devices must be avoided. Thus, option A is correct.

Correct answer: A. By reducing paper use through digital documents

Explanation: Digital documents, online notices, and electronic records can reduce the need to print and transport paper in suitable situations, conserving materials. This benefit is not automatic: devices still consume energy and must be used efficiently. Repeated printing, leaving unnecessary equipment on, and dumping electronic waste increase environmental harm. Therefore, responsible paper reduction through digital documents makes option A correct.
