Installation and configuration

The diagram shows the settings panel of a computer, with five visible sections and a sixth unlabelled card, as shown in the diagram.

Indicate which card you would open for each task: changing the desktop background, creating a new user account, connecting the computer to your home Wi-Fi and turning up the volume. Then look at the key icon on the sixth card: what settings do you think it contains? Give it a name and explain two tasks you would perform in it.

In which settings section would you change each item? (a) screen brightness; (b) keyboard language; (c) clock time; (d) notification volume. Explain how you would reach each section from the settings panel.

On your home computer, each person has their own user account. Explain two advantages of having separate accounts instead of everyone using a single shared account.

Put the steps for creating a new user account on the computer in order and explain the difference between an account with administrator permissions and a standard account: (a) choosing the account type, (b) opening the system settings, (c) setting a secure password, (d) choosing the username.

Order these passwords from least to most secure and explain the criteria you followed: '123456', your date of birth, 'Casa2024', 'T9mQ2vL8'. Then write down two simple rules for creating passwords that are both strong and easy to remember.

What is an operating system update? Explain in your own words why it is best to install updates promptly rather than postponing them repeatedly.

Just as you are about to print a piece of schoolwork to hand in, the computer warns that it is going to restart to install an update. What options does the system normally offer you? Explain what you would do at that moment and how you would configure updates so that it does not happen again at the worst possible time.

In the school's administrative office, automatic operating system updates have been disabled "to prevent the computer from restarting on its own or changing appearance while serving the public". Four months later, the computer cannot access the educational management platform due to a "lack of compatible security certificates", and the browser continually shows infection risk warnings.

1. a) Justify how the decision to block updates has directly caused both problems.
2. b) Design a technical solution in the operating system configuration that allows receiving and installing the necessary security patches without interrupting the workday (from 8:00 to 15:00 h).

What is 'flight mode' (or 'aeroplane mode') on a mobile phone and which connections does it turn off? Describe two situations, inside and outside an aeroplane, where it would be useful to turn it on.

A classmate has difficulty seeing close up and has poor hearing in one ear. Indicate which system accessibility settings would help them (text size, high contrast, subtitles, mono audio, screen magnifier), where they are located, and how each one changes their daily use.

The laptop battery does not last until the end of the lesson. Suggest three system settings to extend battery life (lowering the brightness, shortening sleep time, closing background applications) and explain what comfort or convenience each setting "sacrifices".
