Health Safety and Security at Workplace

Digital payments are often processed quickly, and an incorrect account, UPI ID, phone number, or amount may send money to the wrong person. Checking the receiver’s details and the amount before confirming reduces avoidable mistakes. A user should also review the final confirmation screen and never share a PIN or OTP. The other options are unrelated to payment safety.

A transaction receipt usually records useful details such as the date, amount, transaction ID, and recipient or merchant. If a payment is delayed, duplicated, disputed, or not reflected in an account, these details help the user check the transaction and contact the bank or service provider. A receipt has no role in moving a mouse, shutting down a computer, or recording sound.

Cloud files are linked to an online account, so anyone who obtains the account password may be able to view, change, delete, or share them. A strong, unique password makes guessing and password reuse attacks more difficult; multi-factor authentication adds another layer. Password strength does not affect screen brightness, printer speed, or mouse weight.

Local storage keeps data on a device such as a computer’s drive, USB drive, or memory card. Cloud storage keeps data on remote servers operated by a service and normally allows access through a network, often after signing in. Cloud access may depend on connectivity and account security, while local access depends on the storage device. Thus, A states the key distinction.

Continuous screen work can contribute to eye strain, dryness, headaches, reduced concentration, and discomfort from remaining in one posture. Short breaks allow the eyes to look at distant objects and let the body move and relax. Good lighting, suitable screen distance, and an ergonomic posture also help. Breaks are not for sharing passwords, deleting files, or stopping a printer.

A suitable posture keeps the back supported, shoulders relaxed, feet stable, and screen at a comfortable height and distance. This can reduce unnecessary strain on the neck, back, wrists, and eyes during computer work. Posture should be combined with movement and short breaks because no position is healthy if maintained continuously for too long. It does not affect printer speed, passwords, or filenames.

Digital work involves creating, finding, storing, sharing, and protecting information. Communication helps people exchange information, management keeps it organised and usable, and safety protects accounts, devices, and personal data. These skills therefore support one another in study, work, and daily life. ICT is not limited to games or printers, and these skills are directly related to learning and responsible technology use.

A payment PIN, one-time code, or other secret number is used to prove that the transaction is authorised. If it is disclosed, another person may use it to attempt an unauthorised payment or account access. It does not improve pictures, printer speed, or page refreshing. Such details should be entered only on the genuine payment screen.

A digital receipt can record important transaction details such as the amount, date, time, reference number, and recipient. If the payment is delayed, duplicated, or sent to the wrong person, these details help in checking the transaction and reporting the issue. A receipt has no effect on mouse speed, file colour, or furniture.

A public wireless network may be used by many unknown people and may be fake, poorly protected, or monitored by an attacker. Sensitive activities such as banking can expose account details if the connection or website is not secure. Public networks are not always slow and they can open documents, so A, C, and D are not reliable reasons.

A long password or passphrase containing a varied combination of letters, numbers, and symbols is generally harder to guess or crack. A name and birth date are often easy to discover, while reusing one password lets a breach of one account endanger others. Strong, unique passwords should be protected and, where appropriate, stored in a trusted password manager.

Two-step verification uses two different kinds of evidence, commonly a password plus a code, approval, or biometric check. Therefore, a person who learns only the password may still be stopped at the second step. It does not mean that the account is permanently closed, files are deleted, or the website cannot open; it adds protection during login.

Unexpected prize messages that request passwords, bank details, identity information, or payment are common warning signs of fraud and phishing. The sender may be trying to create excitement or urgency so that the receiver acts without checking. Do not click unknown links or share details; verify the offer through an official channel. The other options do not explain this suspicious pattern.

Malware changes over time, and antivirus programs use updated definitions and detection methods to recognise newer harmful files or behaviour. Updating cannot guarantee complete protection, but it improves the chance of detecting current threats and fixing security weaknesses. It has no connection with chair decoration, mouse colour, or document length.

Unexpected warnings and sudden slowness can have several causes, including unwanted software or malware. A security scan is a sensible first diagnostic step, followed by disconnecting from suspicious activity and seeking trusted technical help if needed. Opening unknown links or sharing a password increases risk, while deleting important files may destroy evidence and data without solving the cause.

Local storage means data saved on a device such as a computer drive, phone, memory card, or external disk. Cloud storage keeps data on remote servers accessed through a service and usually a network connection, although it may also provide offline copies. Cloud services commonly involve an account, so B, C, and D are incorrect.

Cloud files are protected through the account that controls access to them. A strong unique password and multi-factor verification make unauthorised entry harder, while careful sharing permissions provide another layer of control. Sharing the account, choosing an easy password, or opening unknown links can expose files to theft or alteration and therefore weakens cloud security.

Attackers can create a network name that resembles a trusted café, school, or office network and use it to observe traffic or trick users. Checking the exact name with the responsible organisation and using secure websites reduces this risk. Selecting a network name does not change a mouse, print paper, or document colour, so A is the only relevant reason.

Deleting a post from one account or platform does not erase copies that others may have viewed, downloaded, screenshotted, forwarded, or archived. Search results and reposts may also remain for some time. This is why people should consider privacy, audience, and possible consequences before posting. The other options do not explain the persistence of digital content.

Personal information can identify a person, reveal their location or contacts, or expose them to embarrassment, harassment, or fraud. Asking permission respects the person's privacy and gives them control over how the information is used. Some situations also involve legal or institutional rules. Sharing it does not improve computer speed, printer operation, or screen size.
