Big picture
Every time we go online, we leave traces, use other people's work, and face risks from people who misuse technology. Responsible computing means using computers and the internet safely, legally and ethically: protecting your own data and others', respecting intellectual property, avoiding and reporting cyber crime, and disposing of devices properly.
Questions in this area are short and concept-based: identify the type of cyber crime, licence or malware from a description, or suggest a safe practice.
Learning goals

Distinguish proprietary, freeware, shareware and open source software, and common licences.
Identify cyber crimes and malware and explain how to stay safe.

Core ideas
1. Digital footprints
A digital footprint is the trail of data a person leaves while using the internet.
Active footprint: data you share intentionally: posts, emails, comments, form entries.
Passive footprint: data collected without your direct action: browsing history, cookies, location data, IP address.
Digital footprints are hard to erase and can be used for targeted advertising, profiling or even fraud. Think before posting, and review privacy settings.
2. Net and communication etiquette
Net etiquette (netiquette): be ethical (no copyright violation, share expertise), be respectful (respect privacy, respect diversity), and be responsible (avoid cyberbullying, don't feed trolls).
Communication etiquette: be precise (respect others' time and data, avoid unnecessary attachments), be polite, and be credible (check facts before commenting or sharing).
3. Data privacy and protection
Data privacy means a person's control over how their personal information is collected, used and shared.
Good practices: use strong, unique passwords and change them periodically; enable two-factor authentication; don't share OTPs, passwords or bank details; log out from public computers; check that websites use HTTPS before entering details; read app permissions carefully; and keep software updated.
India's Digital Personal Data Protection Act, 2023 sets rules for how organisations process personal data.
4. Intellectual property rights (IPR) and plagiarism
Intellectual property is creations of the mind: software, music, writing, inventions, designs, logos.
Right | Protects | Example |
|---|---|---|
Copyright | Original creative works, including software code | A novel, a song, a computer program |
Patent | Inventions (new and useful processes or products) | A new algorithm built into a device |
Trademark | Distinctive names, logos and symbols | A company logo |
Violations of IPR:
Plagiarism: presenting someone else's work or ideas as your own without credit. Avoid it by citing the source.
Copyright infringement: using copyrighted work without permission (for example, using a photo or song from the internet in a commercial video).
Trademark infringement: unauthorised use of another's trademark.
5. Software licensing
Type | Meaning |
|---|---|
Proprietary software | Owned by a company; source code is closed; must be bought or licensed; can't be modified or redistributed (e.g. Microsoft Windows) |
Freeware | Free to use, but source code is not available and modification isn't allowed |
Shareware | Free for a trial period, after which payment is required |
Free and Open Source Software (FOSS) | Source code is available; users may use, study, modify and redistribute it (e.g. Linux, Python, LibreOffice, Firefox) |
Common licences:
GNU GPL (General Public License): users may modify and redistribute the software, but derived works must also be released under the GPL (a "copyleft" licence).
Apache License: permissive; allows modification and distribution, including in proprietary products, with attribution.
Creative Commons (CC): used for creative content (images, text, music), with options such as attribution (BY), non-commercial (NC), share-alike (SA) and no derivatives (ND).
6. Cyber crime
Cyber crime is any criminal activity that uses a computer, network or the internet.
Crime | Meaning |
|---|---|
Hacking | Gaining unauthorised access to a computer system. Ethical (white hat) hackers do it with permission to find weaknesses; unethical (black hat) hackers do it to cause harm |
Phishing | Fraudulent emails, messages or websites that imitate trusted organisations to steal passwords, card numbers or OTPs |
Ransomware | Malware that encrypts a victim's files and demands payment to unlock them |
Cyberbullying | Harassing, threatening or humiliating someone online |
Identity theft | Stealing personal information to impersonate someone, often for financial fraud |
Denial of service (DoS) | Flooding a server with requests so it can't serve genuine users |
Cyber stalking and online fraud | Repeated online harassment; scams involving fake offers or payments |
Reporting: cyber crimes in India can be reported at the national cyber crime portal (cybercrime.gov.in) or the helpline 1930.
7. Malware and protection
Malware (malicious software) includes:
Malware | Behaviour |
|---|---|
Virus | Attaches itself to a program or file and spreads when the file is run |
Worm | Spreads by itself across networks without needing a host program |
Trojan horse | Looks like useful software but performs harmful actions in the background |
Spyware | Secretly collects information about the user |
Adware | Displays unwanted advertisements |
Protection: install and update antivirus software; use a firewall (which monitors and filters network traffic); avoid downloading from untrusted sources; don't open suspicious attachments or links; keep backups; and update the operating system.
8. The IT Act, 2000
The Information Technology Act, 2000 (amended in 2008) is India's main law on electronic records and cyber crime. It gives legal recognition to electronic documents and digital signatures, provides for e-governance, and defines offences such as hacking, identity theft, publishing obscene material and data theft, with penalties. Cyber appellate tribunals handle disputes.
9. E-waste management
E-waste is discarded electronic equipment: computers, phones, batteries, monitors. It contains toxic substances like lead, mercury and cadmium that can contaminate soil and water and harm health if dumped or burnt.
Management: reduce (buy only what is needed, use devices longer), reuse (donate or refurbish), and recycle through authorised e-waste recyclers. India has E-Waste (Management) Rules that make producers responsible for collecting and recycling their products (extended producer responsibility).
10. Health concerns
Long hours of computer and phone use can cause eye strain, neck and back pain (poor posture), repetitive strain injury in wrists, sleep problems, and internet addiction. Ergonomics (correct desk and screen height, good posture, regular breaks, and the 20-20-20 rule for eyes) reduces these problems.
A reliable approach to questions
For a cyber crime, look for the key action: fake message to steal details (phishing), files locked for money (ransomware), unauthorised access (hacking), online harassment (cyberbullying).
For malware, decide whether it needs a host (virus), spreads alone (worm) or pretends to be useful (Trojan).
For a licence, decide whether the source code is open and whether derived work must stay open (GPL).
For IPR, match the type: work (copyright), invention (patent), brand (trademark).
Connections that matter
Computer networks explains HTTPS and the protocols attackers exploit.
Informatics Practices: societal impacts covers the same issues from a data angle.
Business Studies: small business covers intellectual property rights in business.
Common mistakes
Calling freeware open source. Freeware is free of cost but closed source.
Confusing a virus with a worm. A worm spreads without a host program.
Thinking ethical hacking is illegal. It is done with permission.
Throwing old electronics in household waste.
