Health Safety and Security at Workplace

A backup is a separate copy of important data. If the original is deleted accidentally, damaged by hardware failure, corrupted by malware, or made unavailable, the copy can help restore it. Backup is not intended to change computer weight or mouse speed, so recovering lost information makes option A 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.

A digital receipt or transaction record allows the user to check whether the payment succeeded and whether the amount, date, reference number, and recipient are correct. It can also support a complaint if a problem occurs. It does not shut down a computer or change equipment, so option 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.

Keeping a comfortable distance from the screen helps reduce visual strain caused by viewing the display from too close for a long time. Good workplace practice also includes sitting upright, adjusting screen height and brightness, and taking regular eye breaks. Distance does not shorten passwords, hide files, or stop a printer. Thus, option A gives the relevant health and safety reason.

Continuous screen work and sitting can tire the eyes, muscles, and mind. Short breaks allow a person to change posture, relax the eyes, stretch, and regain attention. A break should not be used to delete data, damage equipment, or leave an account exposed. Thus, reducing tiredness makes option A correct.

The Cc, or carbon copy, field sends a visible copy of an email to additional recipients besides the main To recipients. Everyone receiving the message can normally see the addresses listed in Cc. It is useful for keeping people informed, but confidential addresses should usually be placed in Bcc instead.

Bcc, or blind carbon copy, sends a copy to a recipient while hiding that recipient’s address from the other recipients. This is useful for protecting addresses in a group message. It does not hide an email password, enlarge a file, or clean a keyboard, so those options do not describe Bcc.

An effective email reply should address the subject and the information or question in the original message. It should be clear, polite, and contain only the necessary details. A reply does not need to contain pictures, passwords, or no text. Passwords and other sensitive information should not be shared casually by email.

An unexpected prize message from an unknown sender may be a phishing or fraud attempt. The learner should inspect the sender and message through a trusted method, avoid suspicious links, and never provide passwords, bank details, or unnecessary personal information. Immediate clicking or sharing would increase the risk of account theft.

If the same password is reused and an attacker learns it, several accounts can be opened. Different passwords limit the damage because a compromised password does not automatically unlock other accounts. The practice does not delete accounts, slow the computer, or control a printer.

A suspicious message that asks for personal, financial, or login information may be attempting fraud or phishing. The safe response is to stop, verify the sender through an independent trusted method, and avoid clicking links or sharing details. The other options do not describe this warning sign.

A lock symbol in the browser normally indicates that the connection uses HTTPS encryption, which helps protect data while it travels between the device and the website. It does not prove that the site is honest, safe in every way, or free from scams. The address and source must still be checked carefully.

Software from an unknown source may be modified, fake, or bundled with malware such as a virus or spyware. After installation, it could damage files, steal information, or allow unauthorized access. Therefore, software should be downloaded from trusted websites or official app stores, and its publisher and security warnings should be checked. The other options describe unrelated or false effects.

A separate backup remains available if the main computer, drive, or location is damaged, lost, stolen, or affected by a serious event. This supports recovery of important information. A backup does not change a computer’s color, alter mouse sound, or cut paper; its purpose is to preserve and restore data.

A public computer can be used by many people after you leave. A private downloaded file may expose personal information, and an open account may allow another person to use it. Delete the local file when appropriate, sign out of every account, and avoid saving passwords. These actions protect privacy better than leaving the data behind.

A digital footprint is the record created by online searches, posts, messages, and other activities. Sharing private details impulsively can expose a person to misuse, embarrassment, or future harm because copies may remain online. Checking sources, using strong passwords, and signing out improve safety.
