Health Safety and Security at Workplace

Before clicking a link or opening an attachment, check whether the sender is genuine, the address is correct, and the request is expected. Be cautious about urgency, unusual wording, mismatched domains, or requests for passwords and money. Font size, screen brightness, and receipt time do not establish safety. Suspicious messages should be reported or deleted safely.

Confidential records, customer details, employee information, and passwords should be protected from unauthorised access. Sharing should follow the need-to-know principle: verify the person’s authority and provide only what is necessary for the assigned work. Public posting or sending information without verification can cause privacy breaches and harm.

Phishing messages often use urgency, fear, or a false request from an organisation to trick people into revealing passwords or other sensitive information. A message demanding that a password be shared immediately is therefore suspicious. The other examples describe ordinary, expected communication, though every attachment and sender should still be checked carefully before opening.

A suspicious link may lead to a fake login page, download harmful software, or exploit a security weakness. If a user enters details there, personal or account information may be stolen. The link cannot normally change a fan, chair, or paper. Users should verify the sender and destination and avoid entering credentials on an unexpected page.

Cyber security protects computers, networks, accounts, and digital information from unauthorised access, damage, theft, and disruption. Passwords, updates, safe browsing, access controls, and backups are examples of protective measures. Folding paper, increasing music volume, and decorating a table do not protect digital systems. Thus, protecting information and systems is the correct purpose.

Online information may be accurate, outdated, biased, or false. Checking the author, date, evidence, and agreement with reliable sources helps a student judge its quality before using or sharing it. Believing everything, ignoring the source, or spreading rumours can pass on misinformation. Therefore, checking information against a reliable source is responsible digital behaviour.

Responsible use means using digital devices safely, legally, respectfully, and according to applicable rules. It includes protecting passwords, respecting privacy and copyright, checking information, and communicating politely. Stealing information, spreading rumours, and sharing passwords can harm people and reduce security. Therefore, safe and rule-based use is the correct description.

Two-factor authentication requires a password plus a second proof of identity, such as a one-time code, authenticator-app approval, security key, or biometric check. If a password is stolen, the second factor can still block unauthorised access. It does not remove every password requirement, increase internet speed, or print files. Its main benefit is stronger account security.

A digital footprint is the broad trail of data created by a person’s online activities. It can include posts, comments, searches, purchases, account actions, and information collected by websites or services. Browser history is only one possible part of this trail, not the whole concept. A screen icon and a physical footprint are unrelated meanings of the word footprint.

An unknown sender cannot be assumed to be trustworthy. The message may attempt phishing, spread false information, request money, or contain a link or attachment carrying malware. The email should be checked carefully rather than opened or answered impulsively. Thus, option A gives the valid reason.

Two-step verification requires a second proof of identity after the password, such as a code from an authenticator or a registered device confirmation. If someone obtains the password, this extra check can still block entry. Shutting down a computer, changing a mouse, or printing does not provide this account protection, so A is correct.

An urgent password request from an unknown sender is a common phishing warning sign. Riya should not use the embedded link or disclose her password; she should independently type the organisation's official web address or contact its known support channel. This verifies the request without trusting the suspicious message, so C is correct.

Cloud-storage files are reached through an online account, so an attacker who gains access may read, change, delete, or share them. A strong unique password, multi-factor verification, and careful sign-in practice reduce this risk. The physical table, keyboard, and printer are unrelated; therefore A is correct.

A payment PIN, one-time code, or other secret credential helps authorize a transaction. If it is shared, another person may use it to approve payments or take over an account. Such details should be entered only in the trusted payment service and never disclosed to callers or messages. Thus A is correct.

An open public Wi-Fi network may allow others to observe traffic or create a fake access point. Avoid banking and other sensitive activities unless a trusted, protected connection is used; never send passwords or leave accounts open. These precautions reduce exposure, making option A the safest answer.

Personal information belongs to an identifiable person and may affect privacy, safety, or reputation. Before sharing it online, obtain the person's informed permission and consider whether sharing is necessary and appropriate. Forwarding immediately, hiding the source, or changing the name does not provide consent, so option A is correct.

Several wireless names may appear in a public place, and an attacker can create a look-alike network to collect information. Confirm the correct name and, when possible, ask the provider or use a trusted protected connection. This has nothing to do with a mouse, document thickness, or printer colour, so A is correct.

To judge a website responsibly, examine who created or publishes the information, when it was updated, and whether the author or organization is identifiable and credible. Compare important claims with other reliable sources before accepting or sharing them. Visual design and advertisements do not prove accuracy, and sharing unread information can spread errors or scams.

Software from an unknown website or person may be modified, counterfeit, or bundled with malware such as spyware, ransomware, or a virus. It may steal information, damage files, or weaken system security. Trusted stores, official developer websites, reviews, and security scans reduce this risk. The other options are not normal or guaranteed results of installation.

Antivirus updates add newer malware signatures, detection rules, and security improvements. These updates help the program recognise threats that were created or discovered after the earlier version was installed. They do not increase hard-disk capacity, change screen resolution, or directly improve internet speed. Keeping updates enabled therefore improves the chance of detecting current threats.

Sudden slowness and unfamiliar pop-ups can be signs of unwanted software, malware, or another system problem, although they are not proof by themselves. Running an updated security scan is a safe first step; the user should also avoid unknown links and seek technical help if needed. Sharing passwords or deleting files blindly could worsen the situation or destroy evidence.

Cloud files are linked to an online account, so anyone who obtains the account password may be able to view, change, delete, or share them. A strong, unique password makes guessing and password reuse attacks more difficult; multi-factor authentication adds another layer. Password strength does not affect screen brightness, printer speed, or mouse weight.

Local storage keeps data on a device such as a computer’s drive, USB drive, or memory card. Cloud storage keeps data on remote servers operated by a service and normally allows access through a network, often after signing in. Cloud access may depend on connectivity and account security, while local access depends on the storage device. Thus, A states the key distinction.

Digital work involves creating, finding, storing, sharing, and protecting information. Communication helps people exchange information, management keeps it organised and usable, and safety protects accounts, devices, and personal data. These skills therefore support one another in study, work, and daily life. ICT is not limited to games or printers, and these skills are directly related to learning and responsible technology use.

Unexpected warnings and sudden slowness can have several causes, including unwanted software or malware. A security scan is a sensible first diagnostic step, followed by disconnecting from suspicious activity and seeking trusted technical help if needed. Opening unknown links or sharing a password increases risk, while deleting important files may destroy evidence and data without solving the cause.
