4 ideas in Class 12 Informatics Practices, explained in plain words, with games and quizzes to practise.
Footprints and Digital Citizenship
Part of: Living Well Online
Every visit, mail and post leaves a data trail called a digital footprint. Trails we create on purpose are active, while sites and apps silently record passive trails, and neither can be fully erased afterwards.
Why it matters. Employers, colleges and strangers can read old trails. Posting carefully today protects tomorrow.
Key words
- Digital footprint
- : The data trail left behind by online activity.
- Active footprint
- : Data shared deliberately, like posts and mails.
- Passive footprint
- : Data recorded silently, like visits and location.
- Netizen
- : A citizen of the digital world using online tools.
Try it in two minutes
- Open browser history together and read the trail aloud.
- Sort recent acts into deliberate posts and silent records.
- Draft one polite disagreement reply.
- Check a forwarded message for signs of fakery before sharing.
Try at home. Audit one social profile and delete or privatise anything you would not show a teacher.
Respecting Work Online
Part of: Living Well Online
Ideas get legal shields: copyright guards creative expression automatically, patents guard inventions for 20 years after filing, and trademarks guard brand marks. Licenses rent out usage rights, plagiarism copies without credit, and open licenses like GPL and Creative Commons invite sharing under clear terms.
Why it matters. Copying a picture into homework without checking its license is already an offence. Knowing the shields keeps projects legal.
Key words
- Copyright
- : Automatic legal rights of creators over their expression.
- Patent
- : A filed right guarding an invention for 20 years.
- Trademark
- : A registered mark distinguishing one brand from others.
- Plagiarism
- : Presenting borrowed work as your own without credit.
- Open source
- : Software shared with code open for study and change.
Try it in two minutes
- Credit one borrowed sentence aloud with its source.
- Compare a copied paragraph with a cited one.
- Read one free license condition together.
- Decide which family photos may be shared publicly.
Try at home. Recheck one school project and add missing source credits to every borrowed item.
Cyber Crime and the Law
Part of: Staying Safe and Green
Cyber crime uses computers as target or tool, from break-ins to fake bank mails to data-locking ransom demands. White-hat hackers test defences legally, black-hat crackers break in to steal, and the IT Act punishes online offences.
Why it matters. One careless click can empty an account. Spotting fakes and knowing where to complain limits the damage.
Key words
- Hacking
- : Gaining entry to systems without permission.
- White-hat hacker
- : Tests defences legally to improve security.
- Phishing
- : Fake mails or sites that steal secret details.
- Ransomware
- : Malware that locks data and demands payment.
Try it in two minutes
- Compare a real and a fake sender address dot by dot.
- Practise refusing an urgent money demand received by mail.
- List three people to inform after a suspected fraud.
- Back up one important folder to show ransom-proofing.
Try at home. Check older family mails for phishing signs and report one spam message through the proper channel.
E-waste and Healthy Habits
Part of: Staying Safe and Green
Dead gadgets pile into e-waste rich in recoverable metals but also toxic like lead and mercury. Safe handling means reducing, reusing and routing waste to authorised recyclers, while healthy habits mean upright posture, screen breaks and real-world play.
Why it matters. Dumped gadgets poison soil and water, and marathon screen hours strain young bodies. Small habits protect both planet and person.
Key words
- E-waste
- : Discarded electronic devices and parts.
- Hazardous fraction
- : The toxic share needing special handling.
- Authorised recycler
- : A licensed handler that recovers e-waste safely.
- Screen break
- : A short rest distancing eyes from the display.
Try it in two minutes
- Gather dead batteries and chargers into one box.
- Locate the nearest authorised e-waste collector.
- Set a 20-minute screen-break timer together.
- Straighten chairs and screens to eye level.
Try at home. Hand one dead device to an authorised collector and log a week of screen breaks.
