Health Safety and Security at Workplace

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.

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.

The Bcc field sends a copy to the listed recipients while hiding those addresses from the other recipients. This is useful when sending one message to many people who do not need to know one another’s email addresses, such as a group announcement. It supports privacy and reduces unnecessary exposure of contact details. Cc does not hide addresses, while the other options are unrelated to Bcc.

A digital footprint is the trail of information created by a person’s online activities. Posts, comments, searches, uploaded photographs, and shared files may be stored or copied by services or other users. Therefore, online actions can leave records. The other options are incorrect because a digital footprint is not made only on paper, does not always disappear immediately, and is not limited to printers.

A photograph can reveal a person’s face, identity, location, activity, or personal circumstances. Sharing it without consent may violate that person’s privacy and can cause embarrassment or harm. Asking first respects the person’s choice and is part of responsible digital etiquette. A photo is not automatically public, and sharing it does not shut down a computer or speed up a printer.

Online messages can be forwarded to many people within seconds, even when they are false, incomplete, or taken out of context. Checking the source, date, author, and supporting evidence helps prevent misinformation and possible harm. The other choices describe unrelated actions: verification does not change a mouse, shorten a password, or print a file.

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.
