Introduction to ICT and its role in daily life

Digital documents, electronic communication and online forms can reduce the need for paper in some activities, helping save paper and the resources used to produce it. ICT can also have negative effects if electricity is wasted or electronic waste is handled carelessly. The question asks for a positive effect, so reduced paper use in A is correct.

ICT has a broad role because it supports communication, education, employment, banking, health services, entertainment, government services and access to information. It can make many tasks faster and more convenient, although responsible use is necessary. Limiting ICT to entertainment or computer sales ignores these applications, while increasing paperwork is not its defining role. Hence B is correct.

Online banking allows customers to access selected banking services through a secure website or application. Depending on the bank, users may view balances, transfer money, pay bills or download statements after authentication. It is not related to making paper, playing games or merely viewing a building, so option A correctly states its purpose.

When an audio message is recorded and sent through a mobile phone, messaging application or internet service, it is represented and transmitted digitally. The receiver can play it electronically. It is not written communication only, painting or weather measurement. Therefore, option A correctly identifies the communication type.

A school website can publish notices, calendars, results, instructions and event information so that many students, parents and staff can access them quickly. It provides wider and more convenient reach than giving the message to one person only. A website is a digital service, not a paper-only system, so option A is correct.

A digital calendar records dates, events and schedules and can provide reminders for meetings, examinations, birthdays or appointments. This helps a person plan activities and avoid forgetting important tasks. It does not perform household work such as cooking or washing clothes, and it is not a paper-cutting tool. Therefore, A is correct.

An online form collects details entered into fields and sends them electronically to an organisation or service. It can be used for applications, registrations, surveys, admissions or feedback. The information may be stored and processed digitally, unlike the physical activities in the other options. Thus option A correctly describes the purpose of an online form.

Radio uses electronic communication to transmit audio programmes such as news, educational talks, music and public announcements to listeners. It is therefore a mass communication medium and an example of ICT used for broadcasting information. It does not primarily create documents, copy paper or provide map-based location finding, so A is correct.

Television communicates information through moving images and sound. It can broadcast news, educational lessons, documentaries, cultural programmes and entertainment to a large audience. Typing, scanning and online payment require other devices or software and are not the main function of television. Therefore, showing news and educational programmes in option A is correct.

Online news services can update reports quickly as events develop, allowing readers to receive recent information through an internet-connected device. Readers should still check the publisher, date and reliability because online information is not automatically true. News is not limited to pictures and internet access is normally needed, so A is the valid benefit.

A digital alarm is programmed to produce a sound, vibration or visual alert at a chosen time. It can help a person wake up, begin a task, attend a class or remember an appointment. Printing, internet searching and video calls are separate functions that need other tools, so option A correctly describes a digital alarm.

An online library provides access to digital books, journals, reference materials and other learning resources through the internet. Users can search for a title or topic and read or download material according to the service's rules. It is an educational information resource, not mainly a gaming, food-ordering or tailoring service. Thus A is correct.

An online food-delivery application connects a customer with restaurants or food providers through the internet. The user can browse available items, place an order and often track delivery, subject to the service and location. Word-processing software creates documents, while scanners and printers handle input and output, so option A is the appropriate daily-life ICT service.

A trusted messaging application or email can share photos with intended family members while allowing the sender to choose recipients and privacy settings. The sender should avoid sharing sensitive images publicly and must never send passwords along with them. Posting on every website removes control over access, so option A is the safest suitable choice.

A digital calendar helps users enter, organise and review meetings, examinations, appointments, holidays and other important dates. It can also send reminders, making planning and time management easier. Drawing pictures, recording music and increasing internet speed are functions of other applications or devices. Therefore, option A correctly describes the calendar's use.

An online map displays locations and can help users search for an address, identify nearby places and plan a route between two points. Many mapping services also provide distance or travel-time information. Repairing computers, creating passwords and printing documents are unrelated activities, so option B correctly identifies the main use of an online map.

A digital alarm is useful because it gives a sound, vibration or screen alert at a selected time. It may remind someone to wake up, take part in a class, begin an activity or attend an appointment. Turning off the internet, opening a bank account and scanning documents require different tools, so option C is correct.

Online news can be updated rapidly, so readers may receive reports about recent events soon after information becomes available. The exact speed and accuracy depend on the connection and publisher, so readers should check the source and date. Online news normally needs internet access and is not limited to old stories; therefore D is correct.

Radio is a communication technology because it uses electronic transmission to send audio programmes and messages to listeners. News, education, public announcements and entertainment can reach many people through radio. Generating electricity, writing on paper and preserving food are not the defining functions of radio. Consequently, option A explains why it belongs to ICT.

Television communicates through a combination of sound and moving or still images. It can deliver news, educational programmes, public information and entertainment to a broad audience. Although modern televisions may include additional digital features, their relevant ICT role here is audio-visual communication. They are not limited to calculation or document storage, so B is correct.

A podcast is a digital audio programme or series that is made available through the internet for streaming or downloading. Episodes may discuss news, education, stories, interviews or entertainment, and listeners can often choose when to hear them. A printed map, cable and written examination are not podcasts, so option C is correct.

An online meeting normally needs a device such as a computer, tablet or smartphone connected to the internet, together with a suitable meeting application or platform. A microphone and camera may be useful, depending on the meeting. Paper, a printer or a scanner alone cannot provide the required online connection, so D is correct.

A digital document is stored as an electronic file and can be edited, corrected, copied and shared using a computer or mobile device. It may be sent by email, messaging service or cloud platform without printing it first. Thus, option A states a genuine benefit. Options B, C and D are false because digital files can be stored electronically, created with software and transmitted directly without a printed copy.

An online collaboration service allows authorised users to access a shared document, add content, edit it and sometimes comment at the same time or at different times. This supports group work while keeping changes in a common digital location. Offline printing, paper mail and a calculator do not provide shared document editing, so B is correct.

A digital receipt is an electronic record generated after a payment, purchase or other transaction. It may be delivered by email, SMS or an application and can be saved to verify what was bought, when it was bought and how much was paid. Therefore, option C is correct. A receipt does not make video calls, start a computer or report weather; those functions belong to different tools or services.
