Health Safety and Security at Workplace

Correct answer: A. When a dispute or checking is needed

A digital receipt records useful details such as the date, amount, transaction reference, and recipient. If a payment fails, is duplicated, or is disputed, these details help with checking and reporting the issue. Cleaning a mouse, changing a chair, or painting a computer has no connection with a payment receipt.

Correct answer: A. When the network is not trusted or secure

An untrusted public wireless network may be misconfigured, monitored, or imitated by an attacker. Logging into a private account there can expose credentials or other information, especially without suitable protections. Screen cleanliness, mouse age, and paper colour do not determine network security.

Correct answer: A. Confirm the trusted network name before connecting

Attackers can create network names that resemble a school, shop, or public service. Confirm the exact name and, when possible, the connection details with the responsible provider before joining. Connecting randomly or publishing passwords increases risk; turning off a printer does not protect a wireless connection.

Correct answer: A. Both may need security

Wired and wireless networks differ in how devices connect, but both carry information and can face unauthorized access, malware, or misuse. Security controls such as strong authentication, permissions, and suitable configuration may be needed in either type. A cable does not guarantee zero risk.

Correct answer: A. Important information may be lost

A computer failure can make stored documents, photographs, or records inaccessible or permanently damaged. Without a separate backup, recovery may be impossible or costly. A backup is an additional copy kept so information can be restored after failure. Mouse colour, printer replacement, and chair weight are unrelated outcomes.

Correct answer: A. Information can be recovered even if the main location fails

If the main computer or room is damaged by hardware failure, theft, fire, or another event, a backup stored in the same place may be lost too. A separate location provides resilience and improves the chance of restoring files. It changes neither computer appearance nor printer or paper behaviour.

Correct answer: A. The eyes and body may become strained

Long, uninterrupted screen use can cause eye fatigue, while poor distance and posture can strain the neck, shoulders, back, or wrists. Regular short breaks, suitable screen placement, and a comfortable posture help reduce discomfort. These physical effects do not automatically change passwords, printers, or file security.

Correct answer: A. Digital health safety

Digital health safety concerns the effect of technology use on the body and well-being. Correct posture supports the back, neck, and wrists, while short breaks reduce eye and muscle strain. Email privacy, file extensions, and spreadsheet filtering concern information or software functions, not physical ergonomics.

Correct answer: A. Using digital tools safely, correctly, respectfully, and effectively

Responsible ICT use combines technical skill with safety, privacy, accuracy, respect, and appropriate communication. A responsible user checks information, protects passwords, respects creators and other people, and uses tools for a suitable purpose. Sharing everything or using technology only for games does not express this complete idea.

Correct answer: A. Account security matters in cloud storage, device security matters in local storage

Cloud storage is usually accessed through an online account, so a strong password, secure sign-in, and careful sharing permissions are important. Local storage is kept on a particular device, so device locks, updates, backups, and protection from theft matter greatly. Neither type is automatically safe; the security focus differs according to how the data is accessed.

Correct answer: A. Because information can be recovered even if the main device fails

A main computer may fail because of hardware damage, malware, loss, or theft. If the only backup is stored on that same computer, it may be lost at the same time. A backup in another location, such as a separate drive or secure cloud service, provides an independent copy that can help restore important information.

Correct answer: A. Unsaved changes may be lost

While a document is open, recent changes may exist only in working memory and may not yet be written to permanent storage. A power failure can therefore remove those unsaved changes, although the previously saved version may remain. Saving regularly, and using recovery features where available, reduces this risk.

Correct answer: A. It may become difficult to detect new harmful programs

Malware changes continuously, and antivirus tools use updated definitions and detection rules to recognise newer threats. Old software may still detect some known harmful programs, but it can miss newer or modified ones. Updating the antivirus and the operating system improves protection, though no security tool can guarantee complete safety.

Correct answer: A. A problem in one account can put many accounts at risk

Reusing one password creates a chain of risk. If an attacker obtains it from a less protected website, the same password may unlock email, cloud files, or a payment account. Unique, strong passwords limit the damage from one breach; a password manager and multi-factor authentication can make this practice easier and safer.

Correct answer: A. Because the password is still the first security layer

Two-step verification adds another proof of identity, such as a code or authentication-device approval, but the password commonly remains the first factor. A weak or reused password can still be stolen, guessed, or used in attacks, and some recovery situations may depend on it. Strong unique passwords therefore remain necessary.

Correct answer: A. To avoid wrong payment and fraud

Checking the recipient’s name, payment amount, and identification details before confirming helps catch typing mistakes, wrong recipients, and suspicious transaction information. It does not guarantee that every fraud will be detected, but it is an important safety step. The user should also use the official payment application and review the confirmation screen.

Correct answer: A. It can provide proof in problem, dispute, or checking

A digital receipt records useful transaction details such as the date, amount, reference number, and often the recipient or service. If a payment is delayed, duplicated, disputed, or sent incorrectly, these details help the user communicate with the bank or service and provide evidence. The receipt should be stored securely and not posted publicly.

Correct answer: A. Save the file first, then close unnecessary applications

The open important file may contain changes that would be lost if the computer were shut down or an application closed unexpectedly. Saving first protects the current work. After that, closing unnecessary applications releases memory and processing resources, which may improve performance. Abruptly cutting power or deleting files is unsafe and unrelated to solving the slowdown.

Correct answer: A. Maintain correct posture, proper distance, and short breaks

Good computer ergonomics combines several habits: sit with the back supported, keep the screen at a comfortable height and distance, position the keyboard and mouse naturally, and take brief regular breaks. These steps reduce eye strain and static load on the neck, shoulders, and back. Sitting very close or ignoring chair height can increase discomfort rather than prevent it.

Correct answer: A. Eye strain and reduced focus

Long, uninterrupted screen viewing can make the eyes feel dry, tired, or uncomfortable, and mental fatigue may reduce attention. Short breaks allow the eyes and mind to relax and can improve comfort and concentration. The effect is not that a printer becomes faster, a password changes, or a file becomes smaller; those options are unrelated to screen habits.

Correct answer: B. Do not share without checking source and facts

Urgent, threatening language is often used to make people react before thinking. If a message has no credible source, its claim should be checked through reliable channels before sharing. Thus option B is correct. Forwarding it to more groups spreads possible misinformation, and replying with a password creates an additional security risk.

Correct answer: A. Correct posture, proper distance, and short breaks

Long computer use is safer when the back and neck are supported, the screen is placed at a comfortable distance and height, and brief breaks are taken regularly. Looking away and changing position can reduce eye and muscle strain. Sitting too close, working continuously, or ignoring chair height can increase discomfort. Good ergonomics combines all three measures in option A.

Correct answer: A. Local area network

A network limited to a small geographical area, such as one room, office, school, or building, is called a Local Area Network, or LAN. File sharing between computers in the same building fits this definition. Email is a service, Recycle Bin is a storage feature, and a security scan is a protective action, not a network type.

Correct answer: A. Confirm the correct and trusted network name

A public place may contain an imitation or unsafe Wi-Fi network whose name resembles the genuine one. Confirming the network name with staff or the authorised provider reduces the chance of exposing login details. Connecting randomly, revealing a password, or opening accounts on many networks increases risk and does not provide protection.

Correct answer: A. Both may need information security and permissions

Both wired and wireless networks carry data and can be exposed to unauthorised access, malware, or misuse. Therefore, both may require authentication, permissions, secure settings, and suitable protection. Wireless networks are not automatically unsafe, and wired networks are not automatically safe; the connection medium alone does not remove security responsibilities.
