Introduction to ICT and its role in daily life

The governing concept is the digital divide, meaning unequal access to digital devices, connectivity, skills, or useful online services. When some students lack a suitable device or reliable internet, they cannot participate in online lessons as fully as their peers, creating an educational gap. Equal access, a computer lab, or a teacher using slides does not by itself show inequality. Therefore, option D is the clearest example.

The governing concept is continuity of care through reliable information access. When an authorised doctor can view a patient’s earlier digital records, medicines, and relevant reports, the doctor can understand the treatment history and make better-connected decisions. Thus option A is correct. Creating a new record repeatedly loses context, destroying reports removes useful evidence, and removing identity can create safety and identification problems. Privacy controls must still be followed.

The governing concept is responsible digital citizenship. Before sharing a post, a user should check whether the information is credible and should respect the privacy, consent, and dignity of other people. Option C combines both essential behaviours, so it is correct. Sharing unknown news can spread misinformation, posting a private image without permission violates privacy, and giving away a password weakens account security. Responsible use balances communication with safety and respect.

The governing concept is safe and informed use of digital services during disruption. A temporary outage should first be confirmed through the service’s official website, app notice, or verified support channel. The user can then wait, retry later, or use a trusted alternative without exposing credentials. Option D is correct. Repeated wrong passwords may lock an account, publicising personal data creates risk, and unknown links may lead to phishing or malware.

The governing concept is that ICT can perform more than one information function in a connected process. Saving the file in cloud storage preserves the information for later access, while sending its restricted link transmits the information to the teacher. Therefore option A includes both storage and communication. Keeping paper in place is not digital communication, turning off a screen performs neither function, and an empty message carries no meaningful information.

The governing concept is the chain effect of credential compromise. If the same password is used on several websites and one service suffers a breach or phishing attack, an attacker may try that password on the other accounts. Thus option B is correct: one leak can expose multiple accounts. Reuse does not automatically improve security, does not make the password impossible to remember, and has no direct effect on internet speed. Unique strong passwords and multi-factor authentication reduce the risk.

The governing concept is evaluating online trust and reducing transaction risk. A secure connection helps protect data while it is transmitted, and verified seller information gives the buyer a way to assess the business and seek support. Therefore option D is the best answer, although users should also check reviews, return policies, and payment warnings. Bright advertising, very low prices, or free gifts can be used to attract users and do not by themselves prove legitimacy.

The governing concept is effective emergency communication: a warning must be accurate, timely, and capable of reaching the affected population. Option A combines all three requirements, so people can understand the danger and act before conditions worsen. Attractive images do not ensure safety, a late warning reduces available response time, and unverified messages can create panic or spread false information.

The governing concept is the efficient use of ICT for storing and retrieving information. Digital records can be searched, filtered, sorted, copied, and updated quickly, which is especially valuable when thousands of entries are involved. Thus option C is correct. Lack of electricity or a device prevents digital access, never searching removes the main advantage, and public exposure without security is unsafe rather than useful.

The governing concept is transparency through wider and more timely access to information. When a farmer compares current prices from several digital sources, it becomes easier to identify differences, question unreliable claims, and make an informed selling decision. Therefore option A is correct. Hiding prices, showing only old data, or relying on an unsupported statement reduces transparency and may mislead users.

The governing concept is authentication, the process of checking whether a user is the authorised person. In an online class, identity verification can prevent unauthorised access and help connect attendance, assignments, and progress records with the correct student. Option B states both purposes. Changing screen colour or turning off the internet is unrelated, while using one shared password weakens security.

The governing concept is selecting a communication channel according to purpose, formality, urgency, and confidentiality. Email is suitable for a formal document because it preserves a structured record and attachments, while instant messaging is useful for a brief urgent update. Option C makes this appropriate distinction. The other choices ignore the task, create unnecessary duplication, or expose confidential information.

The governing concept is access control and data integrity. If every viewer can edit a shared document, someone may accidentally or deliberately alter, delete, or corrupt important information. Restricting editing permission allows only authorised users to make approved changes, so option D is correct. The restriction does not increase file size or internet speed, and allowing everyone to delete content creates the very risk being prevented.

The governing concept is network security and protection of sensitive data. Public Wi-Fi may be poorly secured, allowing attackers on the same network to attempt interception, fake access points, or other attacks against users who transmit payment details. Thus option B is correct, although risk is not automatic in every public network. Payment failure, screen damage, and automatic account closure are unrelated claims.

The correct answer is C because computer speed only reduces processing time; it cannot transform inaccurate, incomplete, or misleading input into reliable information. This illustrates the principle “garbage in, garbage out”: poor input generally produces poor output, even when processing is extremely fast. Accurate data and reliable sources support quality, while careful review can detect errors. Software updates may improve security or performance, but they do not automatically correct wrong data.

The correct answer is D, privacy. A medical record contains sensitive personal and health information, so it should be accessed or shared only by authorised people for a valid purpose. Sending it to the wrong person exposes confidential information and represents a privacy breach. Entertainment and productivity describe possible uses or outcomes of technology, not protection of personal data. Automation concerns work being performed automatically and does not identify the harm in unauthorised disclosure.

The correct answer is A. A spreadsheet validation rule compares an entry with preset conditions, such as an allowed range, format, or list, and blocks or flags an invalid value. This automated check reduces common entry errors before the data is used. Guesswork can introduce mistakes, and sending an unchecked file leaves errors undiscovered. Repeating calculations manually may sometimes verify work, but it also creates additional opportunities for copying or arithmetic errors.

The correct answer is C because ICT can produce a mixed environmental outcome. Digital documents and online communication may reduce paper use, printing, and physical transport. However, servers and personal devices require electricity, and discarded electronics create e-waste that may contain harmful materials. The other choices describe impossible or incomplete conditions: devices need energy, and merely storing old equipment does not solve its environmental impact or ensure safe recycling.

The correct answer is D. An unexpected message may contain a fake website designed to imitate a bank and collect usernames, passwords, card numbers, PINs, or one-time codes. This social-engineering method is called phishing. Entering details through the suspicious link can give them directly to a criminal. The other options are unrelated to the action and do not describe a security consequence. Users should verify the sender and open the bank through its official app or address.

The correct answer is C. A shared document lets several people contribute to the same work, which supports collaboration. Its version history records what was changed, when it was changed, and often which account made the change; that trace makes responsibility easier to identify and review. Anonymous editing removes accountability, and having no history removes evidence. Verbal discussion may support teamwork but does not by itself create a reliable record of file changes.

The correct answer is D because access depends on both connectivity and service design. Improving network infrastructure addresses the underlying connection problem, while lightweight pages and offline-supported features use less data and continue to help when the signal is intermittent. Closing services removes access, expensive devices can deepen the digital divide, and blaming users solves nothing. An inclusive ICT approach adapts technology to local conditions rather than assuming fast internet is available everywhere.

A balanced evaluation considers both advantages and limitations. ICT can make communication faster, services more accessible and everyday tasks more convenient, but users must also manage privacy, security, excessive use, misinformation and unequal access. Option B includes benefits as well as the need for responsible use, so it is correct. Options A, C and D are absolute or excessively narrow claims and ignore important real-life conditions.

The system first captures the student's arrival time, so it performs data collection. It then records and handles that information to determine the attendance event, which is processing. Finally, it sends the result to parents, which is communication. Thus option C correctly identifies the complete sequence. Options A and B describe only one part of the process, while D is unrelated because the system is retaining and using the record.

Remote consultation is an ICT-enabled service that depends on several connected elements. The patient's report is digital data, devices capture or display information, a network transfers it, and a communication service supports the video interaction. Therefore option B is correct because it includes the required combination. A, C and D may be parts of healthcare work, but none alone can transmit the report and conduct a live remote consultation.

A reservation system keeps seat information in a shared, centrally managed record. When one passenger books a seat, the system updates its status immediately, so another booking request sees that the seat is unavailable. Option A correctly combines centralised control with real-time updating. Handwritten copies, disconnected records and verbal confirmation cannot reliably synchronise availability across booking locations, so options B, C and D are unsuitable.
