Health Safety and Security at Workplace

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.

A home router connects local devices such as phones, computers, and smart devices to one another and usually provides access to the internet through the service connection. It directs network traffic between these devices and other networks. Printing, sound recording, and renaming a file are functions of other hardware or software, not the router’s basic role.

A wired network uses physical cables to connect devices. Because the connection is less affected by wireless interference and signal range problems, it can be stable and reliable in many situations. Its benefit is not that it works without wires. Drawing pictures and deleting passwords are unrelated activities and are not network benefits.

A wireless network uses radio communication, such as Wi-Fi, so devices can connect without running a separate cable to each one. This improves mobility and makes adding devices convenient. Wireless convenience does not mean files are deleted or passwords are shared; encryption and a strong network password are still important.

Correct chair and table height helps keep the back supported, shoulders relaxed, and wrists and eyes in a comfortable position. This reduces unnecessary strain during computer work and supports good posture. It has no effect on password secrecy, printer speed, or the size of a file.

ICT devices and online services hold personal information, files, messages, and accounts. Safe practices such as strong passwords, careful clicking, updates, backups, and privacy awareness reduce the chance of loss, fraud, or unauthorized access. The purpose is much broader than games or decoration.

A public computer may be used by strangers after the current session. If the email account remains open or private files and downloads remain saved, another person may read or misuse them. The user should sign out, remove personal files and downloads, and avoid saving credentials. Forwarding messages or leaving the account open creates additional privacy risks.

An unknown link requesting bank details is a strong warning sign of phishing or fraud. The recipient should not open it, enter information, or forward it. Instead, verify the request through the bank’s official app, website, or known contact channel. Passwords, account numbers, and one-time codes should never be supplied through an untrusted message.

On many desktop operating systems, a normally deleted file is first moved to the Recycle Bin rather than immediately erased. The user can open the bin, select the file, and choose Restore to return it to its earlier location. A monitor, keyboard, and speaker are hardware devices and do not store deleted files in this way.

A backup is an additional copy of data kept so that it can be recovered after accidental deletion, hardware failure, corruption, theft, or another loss. It does not change the appearance of a mouse, adjust screen brightness, or replace furniture. Therefore it is most useful when original data is unavailable or damaged.

A strong password should be long, difficult to guess, and different for each important account. Combining varied characters can help, but length and uniqueness are especially important; a memorable passphrase can also be strong. Names and birth dates are easy to guess, while reusing one password allows a breach of one account to endanger all others.

Two-step verification requires an additional check after the password, such as a code, approval, or security key. If someone learns the password, the second factor can still block unauthorized access. It does not rename files, control a printer, or exist mainly to slow a computer. The extra step improves account protection, though it must also be kept secure.

A public wireless network may be poorly secured, falsely named, or monitored by an attacker. Banking involves sensitive credentials and financial information, so exposure could cause serious harm. A trusted private network or suitable secure connection is safer; speed and picture display are not the security issue.
