Health Safety and Security at Workplace

Checking the recipient name, amount, and identifying details helps confirm that the payment is going to the intended person for the intended value. It can reveal a typing error, wrong account, altered QR information, or a fraudulent request before money is sent. These checks are more relevant than any hardware action.

Public Wi-Fi is shared and its security may be unknown; a fake hotspot or poorly protected network can expose sensitive activity. Banking should preferably be done through a trusted private network or mobile data, with secure site and account protections. Public Wi-Fi is not automatically dangerous for every task, but sensitive banking is best avoided on it.

A camera can unintentionally reveal documents, personal data, passwords, or other confidential material to meeting participants. Changing the background, moving the documents, or turning off the camera removes or reduces that exposure while allowing the meeting to continue. Sharing a picture or reading a password makes the privacy problem worse, and simply allowing others to see the documents is not responsible.

Deleting a post from one account does not undo copies that others may have taken through screenshots, downloads, forwarding, or reposting. People may also have formed opinions or acted on the content before deletion. This is why users should consider the possible digital footprint and consequences before posting sensitive material.

A photograph can identify a person and may reveal their location, activity, or personal context. Sharing it without permission can interfere with that person's control over personal information and therefore affect privacy. Before posting someone else's image, seek consent and consider whether the audience and purpose are appropriate.

Healthy computer use combines several habits rather than relying on one action. Sitting with back supported, keeping the screen at a comfortable distance and suitable height, positioning the hands comfortably, and taking short regular breaks can reduce eye, neck, shoulder, and back strain. Sitting too close, working continuously, or ignoring chair height can increase discomfort and poor posture.

A browser security indicator generally describes how the connection is encrypted; it does not prove that the website owner or request is trustworthy. An unexpected password request related to a scholarship may be phishing. The student should stop, avoid entering credentials, and verify through an official channel, so C is correct.

Permissions determine whether users can view, edit, delete, or manage items in a shared folder. If students can edit despite needing read-only access, the folder or file permission is probably too broad and should be changed to view-only. Mouse speed, brightness, and print colour do not control editing rights, so A is correct.

A network that connects computers within a small geographical area, such as one room, building, school, or office, is called a Local Area Network (LAN). Because the computers in the question share files inside one building, LAN is the correct answer. Email is a communication service, while Recycle Bin and security scanning are not network types.

Similar Wi-Fi names in a public place may include an imitation network created to capture information. Before signing in or opening a private account, confirm the exact network name with the venue or a trusted staff member. Connecting randomly, sharing passwords, or using every network increases risk.

Both wired and wireless networks carry data and may connect users to shared resources. Therefore, both require suitable security controls, access permissions, and safe configuration. Wireless networks can face interception risks, while wired networks can also suffer unauthorized physical or network access; neither is automatically risk-free.

Cloud storage is protected through an online account. If its password is short, common, or easy to guess, an unauthorised person may enter the account and view, copy, change, or delete stored files. A weak password does not mechanically damage a mouse, printer, or monitor; those options are unrelated to account security.

Local storage keeps data on a device such as a computer, phone, or external drive, so protecting that device, its access controls, and backups is important. Cloud storage is accessed through an online account, so strong passwords, verification, and careful sharing are important there. Both forms need protection; local storage is not automatically available everywhere.

Cloud storage permits access from different places, but that convenience makes account protection essential. A strong, unique password reduces guessing risk, and additional verification provides another check if the password is exposed. Sharing the account or using an easy password increases risk, while a file’s name does not protect the account.

A backup is useful only when it provides an independent copy that can survive a failure affecting the original. If both the original and backup are stored on the stolen device, one theft can remove both copies. Keep another copy on a separate device or secure location and test that it can be restored.

Unsaved work is commonly held temporarily in main memory while an application is running. Volatile memory loses its contents when power is removed, so unsaved changes may disappear. Saving frequently writes the work to permanent storage, such as a drive, where it can remain after shutdown.

Unknown files may contain malware, including viruses or other harmful programs. Outdated antivirus software may lack the latest detection information, so it can miss newer threats. Opening such files combines unsafe behaviour with weaker protection and increases the chance of infection. Updating security software and avoiding untrusted files reduce the risk.

Slowness, unexpected messages, and unknown applications can indicate malware or another security problem, although they are not absolute proof. Do not click suspicious content or share passwords. Disconnect or report the issue when appropriate, update protection, and run a trusted security scan before taking further action.

Reusing one password creates a chain of risk. If a criminal obtains it from one website, a data leak, or a phishing message, the same password may unlock email, cloud files, and payment services. Use a different strong password for every important account and protect them with multi-factor authentication.

Two-step verification adds another proof of identity, such as a code or approval on a trusted device, after the password is entered. It does not replace the password. A strong, unique password makes the first login barrier harder to defeat, while the second step provides extra protection. The other options have no connection with account authentication.
