Introduction to ICT and its role in daily life

Digital etiquette means behaving respectfully and responsibly in an online environment. Muting the microphone when not speaking, using the class chat for relevant messages, and waiting for one's turn reduce disturbance and help everyone learn. Spreadsheet formulas, print preview, and file extensions are technical features unrelated to behaviour in a remote class.

A camera can unintentionally reveal names, addresses, account details, school records, or other private information in the background. Changing the background, moving to a clear area, or turning off the camera prevents meeting participants from viewing or recording those details. Allowing people to read the documents or sending their picture increases exposure, and saying a password aloud is also unsafe. Thus, option C best protects privacy.

Deleting a post from one account or platform does not undo copies that others may have taken. People may have viewed it, downloaded it, taken a screenshot, or forwarded it before deletion. This lasting possibility is part of a digital footprint, so users should consider privacy and consequences before posting rather than assuming deletion is complete.

A photograph can identify a person and reveal where or how they were photographed. Sharing it without permission removes the person's choice about who sees that personal image and may cause embarrassment or harm. Therefore, the privacy right is involved. Printing speed, mouse control, and spreadsheet calculation do not describe the affected personal right.

An online image is usually created or published by a person, group, or organisation. Naming the source acknowledges that creator and helps readers find the original work. Attribution alone does not automatically grant permission for every use, so users should also follow the image's licence or ask permission when needed. The other choices are unrelated.

Plagiarism means presenting another person's words or ideas as one's own without proper acknowledgement. Copying a complete answer and adding one's name misrepresents authorship and prevents honest assessment of the student's learning. A student should understand the source, write in their own words where appropriate, and cite the source instead of claiming the original work.

Long computer use can cause eye fatigue and physical strain when posture or viewing distance is poor. Sitting comfortably with the screen at a suitable distance, supporting the back, positioning the chair well, and taking short breaks helps reduce these problems. Sitting very close, skipping breaks, or ignoring chair height increases discomfort rather than improving health.

Information and Communication Technology is shortened to ICT. The letters come from the first letters of Information, Communication, and Technology: I, C, and T. ITC, CTI, and TIC use the same letters in a different order, so they do not represent the accepted abbreviation.

ICT includes technologies that help people collect, process, store, retrieve, and communicate information. Computers, phones, networks, and software support these activities in many areas. Games or drawing may be individual uses, but they are not the main purpose. Therefore B correctly describes the broad role of ICT.

A computer is an ICT device because it accepts, processes, stores, and communicates digital information. A spoon, chair, and pencil are useful physical objects, but they do not normally perform digital information functions. Therefore option A is correct. The question tests recognition of a basic digital technology device.

A mobile phone is an ICT device because it can transmit and receive information through calls, text messages, email, and internet services. These functions involve communication and digital information. Telling time or providing light may be possible on some phones, but those are not the main reasons it is classified as ICT.

Email is an electronic communication service used mainly to send and receive digital messages through the internet. A message may also include documents, images, or other attachments. Therefore, option A is correct. Washing clothes, cooking food, and cleaning a room are physical household activities, not the main purpose of email.

An online class uses internet-connected devices and digital platforms to deliver lessons, communicate with teachers, submit work, or join discussions. These activities apply ICT to education. It may sometimes include interactive or entertaining content, but its main purpose here is learning. Therefore B is the correct answer.

The internet is a worldwide network that allows people to access information and communicate with others. Through it, users can search for knowledge, send messages, use online services, and share digital content. It does not provide only electricity, paper, or musical instruments; those options describe neither its main purpose nor its broad capabilities.

A video call enables people in different places to communicate in real time using both sound and moving pictures. Participants can see and hear one another through a connected device and network. Printing photographs, playing games, and binding books are separate activities and do not describe the primary communication function of a video call.

An ATM is a computerized banking system connected to a bank network. After authentication, it can display account information and support permitted transactions such as cash withdrawal or balance checking. Stitching, harvesting, and construction are not ATM functions. Therefore A correctly identifies ICT use in banking.

Online shopping uses websites or apps to display product information, receive an order, process payment, and provide updates about delivery. These digital activities are enabled by ICT. Physical work such as lifting goods may occur later, but it is not the central ICT role. Therefore A is correct.

UPI allows money to be transferred electronically between bank accounts through an authorised app and a secure payment process. No physical cash needs to be exchanged at the moment of payment. Writing, drawing, and reading are not payment methods. Therefore option A is the clear example of digital payment.

GPS, or the Global Positioning System, uses signals from satellites to help determine the position of a receiver on Earth. It is widely used in maps, navigation, route planning, and location-based services; therefore, option A is correct. Heating food is done by an appliance such as a microwave, cutting cloth requires a tool, and filtering water uses a filter. GPS provides location information, not a physical processing function.

Hospitals can use ICT to create, update, store, and retrieve patient records, such as appointments, test results, and treatment details. Proper access controls are important for privacy. Building walls, planting trees, and organising games are not the intended digital record-keeping use. Therefore A is correct.

An online railway booking system uses a website or application, a network, digital records, and often electronic payment to reserve travel. This is a travel service supported by ICT. It is not primarily entertainment, agriculture, or handicraft. Therefore option A correctly identifies the sector and technological use.

Storage means saving data or files so they can be retained and accessed later, using devices or services such as a drive or cloud storage. Printing creates a paper copy, calculation processes numbers, and painting creates an image. Therefore A correctly names the function of keeping information.

Data means raw facts, figures, symbols, or observations collected for possible use. It may include numbers, words, images, or sounds, so it is not limited to pictures or sound. After processing and interpretation, data may become useful information. Therefore A is the best simple definition.

Raw data consists of facts or figures that may not yet have a clear meaning. When data is organized, calculated, or otherwise processed so that it becomes meaningful and useful, it is called information. A keyboard, mouse, and cable are hardware components or accessories, not names for processed data.

A computer mouse is an input device. Moving it generally moves the pointer on the screen, and clicking or double-clicking allows the user to select, open, or operate items. A microphone is used for recording sound, a printer produces paper copies, and a monitor displays video, so those functions do not describe the mouse’s main use.
