    Downloading files from an unknown source poses a risk of malware infecting a computer. When files are downloaded from an unknown source, there is a higher chance of those files containing malicious software or viruses.

When accessing the Internet, whether through browsing websites, downloading files, or using online services, there is a possibility of encountering malicious content or websites that can infect the smartphone with a virus. This can happen through clicking on malicious links, downloading infected files, or visiting compromised websites. Therefore, using the Internet on a smartphone increases the vulnerability to potential virus infections.

    To reduce eyestrain you should...

    • Use a colour screen

    • Sit closer to the screen

    • Take frequent breaks

    • Close your eyes

    Correct Answer
    A. Take frequent breaks
    Explanation
    To reduce eyestrain, taking frequent breaks is recommended. This is because staring at a screen for extended periods can cause strain on the eyes, leading to discomfort and fatigue. By taking regular breaks, such as looking away from the screen every 20 minutes or so, the eyes are given a chance to rest and refocus. This can help prevent eye strain and reduce symptoms like dryness, blurred vision, and headaches.

    A good password policy will force users to...

    • Always keep the same password

    • Change passwords once a year

    • Share password with only one or two people

    • Change password every month

    Correct Answer
    A. Change password every month
    Explanation
    A good password policy will force users to change their password every month. This is because regularly changing passwords helps to enhance security by reducing the risk of unauthorized access. By changing passwords frequently, it becomes more difficult for hackers to guess or crack passwords, as they have less time to exploit them. This practice also helps to mitigate the impact of compromised passwords, as they become outdated and less useful over time. Additionally, changing passwords regularly encourages users to create stronger and more complex passwords, further strengthening the overall security of the system.

    Explanation
    Setting the screen to switch off automatically if idle helps in saving energy because when the screen is not in use, it consumes unnecessary power. By enabling the automatic switch-off feature, the screen will turn off after a certain period of inactivity, reducing energy consumption and contributing to energy savings.
