Health Safety and Security at Workplace

A photograph can identify a person and reveal where, when, or with whom they were present. Sharing it without permission may remove the person’s control over personal information and therefore affect privacy. The appropriate approach is to ask before sharing, especially when the image is in a private group or could embarrass or harm the person.

A network that connects computers within a limited area such as a room, building, school, or small office is called a Local Area Network, or LAN. It supports local file and resource sharing. Email, Recycle Bin, and security scanning are services or tools, not network types.

Cloud storage is normally linked to an online account. A weak or easily guessed password can let an unauthorized person sign in, view, copy, alter, or delete stored files. It does not physically damage a mouse, change the monitor size, or make a printer produce paper.

A payment receipt records transaction evidence. The amount shows how much was transferred, the time helps locate the event, and receiver details help identify where the money went. A transaction or reference number may also help in a dispute. Hardware colours and furniture settings do not verify a payment.

A photograph can identify a person and may reveal information about their activities, location, or circumstances. Sharing it without permission can therefore interfere with that person's privacy and control over personal information. Asking before sharing is respectful, although additional rules may apply for minors or sensitive images. The other options are unrelated technical functions.

Blind carbon copy, or Bcc, sends the message to listed recipients without displaying those addresses to the other recipients. This helps protect address privacy in a group email. The To and Cc fields normally expose the listed addresses, while Subject describes the message and Attachment carries a file rather than controlling recipient visibility.

Healthy self-care means managing physical health, mental well-being, work, study, and rest in a balanced way. It is not the same as avoiding responsibility or working continuously. Proper sleep, nutritious food, breaks, emotional awareness, and planned work help maintain energy and reduce unhealthy stress. Therefore, option D is the complete meaning.

Balanced self-care includes adequate sleep, nutritious food, breaks, and a sustainable work routine. Studying continuously without rest and sleep may reduce attention, energy, memory, and the ability to work safely and effectively. The other three behaviours support healthy preparation. Thus, option D shows the absence of balanced self-care rather than productive self-management.

An unsourced message may be false, outdated, or deliberately misleading. Exam cancellation is important information and should be confirmed through the school, examination authority, official website, or another recognised channel before anyone acts or forwards it. Immediate sharing can spread confusion, while sending a password creates a separate security risk. Hence, B is responsible.

Blind carbon copy, or BCC, sends the message to recipients without displaying the BCC address list to the other recipients. This protects email-address privacy in a group notice. The To and CC fields normally expose the listed addresses to recipients, while Subject describes the message and Attachment carries a file. Therefore, BCC is the suitable field.

Reply All addresses the response to the original sender and the other recipients included in the conversation. If the content was intended to be private, those additional people may see information that was not meant for them, creating a privacy or confidentiality problem. The sender should use Reply and check the address field before sending. Thus, A is correct.

A network limited to a small geographical area, such as one room, building, school, or office, is called a Local Area Network, or LAN. File sharing between computers in the same building is a typical LAN activity. Email, Recycle Bin, and security scanning are services or tools, not network types.

In a public place, an attacker may create a fake wireless network with a name similar to a genuine one. Connecting to it can expose login details or other private information. Therefore, confirm the exact network name with the venue or a trusted person before signing in. The other choices increase risk rather than reduce it.

Both wired and wireless networks transmit data and allow devices or users to access shared resources. Consequently, both can require authentication, permissions, secure settings, and protection from unauthorized access. Wireless connections may face additional radio-signal risks, but a wired connection is not automatically safe. The other statements wrongly claim that security is unnecessary.

Cloud storage is controlled through an online account. A weak or easily guessed password can allow an unauthorized person to sign in, read, copy, alter, or delete stored files. The safer approach is to use a long, unique password and additional verification where available. Hardware changes are unrelated risks.

Local storage keeps data on a device such as a computer, phone, or external drive, so device access, locks, updates, and backups are important. Cloud storage is reached through an online service and usually depends strongly on account credentials, permissions, and secure sign-in. Both need protection; the difference is where access and control are mainly managed.

Cloud storage permits access from different places, so anyone who obtains the account credentials may also reach the stored files. A strong, unique password reduces guessing and reuse risks, while additional verification adds another barrier at sign-in. Sharing the account or choosing an easy password weakens protection; a file name does not secure the account.

Password reuse creates a chain of risk. If the password is guessed, stolen in a data breach, or disclosed through one service, an attacker may try the same password on the email, cloud, and payment accounts. Using a different strong password for each important account limits the damage. Reuse does not make accounts safer and has no effect on a printer or monitor.

Two-step verification adds a second proof of identity, such as a code or approval on a trusted device, but it does not replace the password. A strong, unique password makes the first step harder to guess or steal. If the password is weak, an attacker may still attempt access or exploit another weakness, so both protections should be used together.

A payment PIN, one-time code, or similar secret should not be disclosed to an unexpected caller. Urgent language and claims that an account must be saved are common warning signs of fraud. End the call if necessary, contact the bank or service through its official app or published number, and check the account there. The other choices expose the secret.

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.

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.
