Societal Impacts of Information Technology
The rapid growth of information technology (IT) and the internet has transformed the way people live, work, learn, and communicate. This chapter explores the positive and negative impacts of computing on individuals and society, along with the ethical and legal dimensions of using technology responsibly.

Digital Footprint
- Every time you use the internet — browsing, posting, shopping, or logging in — you leave a digital footprint: a trail of data about your online activity. This can be:
- Active: data you deliberately share (social media posts, form submissions).
- Passive: data collected without explicit action (cookies, IP addresses, browsing history).
Awareness exercise
When you search for a product online and then see its advertisement on a different website, that is passive digital footprint data being used by advertisers through tracking cookies.

Net Etiquette (Netiquette)
- Netiquette refers to the accepted code of polite behaviour on the internet. Key rules include:
- Respect others in online communication; avoid offensive language.
- Do not share misinformation or fake news.
- Respect privacy — do not share others' personal information.
- Avoid CAPS LOCK in messages (considered "shouting").
- Give credit when sharing others' work.

Data Protection and Privacy
Personal data (name, address, Aadhaar, financial info) must be protected. Key concepts:
- Confidentiality: information is accessible only to authorised persons.
- Integrity: data must be accurate and unaltered.
- Availability: data must be accessible to authorised users when needed.
The CIA Triad
Confidentiality + Integrity + Availability = CIA Triad of information security.

Cybercrime
Cybercrime is any criminal activity carried out using computers or the internet.
| Type | Description |
|------|-------------|
| Hacking | Gaining unauthorised access to systems |
| Phishing | Fake emails/sites to steal credentials |
| Cyberbullying | Using digital media to bully or harass |
| Identity theft | Stealing personal info for fraudulent use |
| Malware | Viruses, worms, trojans, ransomware |
Phishing scenario
You receive an email claiming to be from your bank asking you to "verify your account" by clicking a link. The link goes to a fake site designed to steal your password — this is phishing.

Cybersecurity Practices
Safe computing habits
- Use strong passwords (mix of uppercase, lowercase, digits, symbols; at least 8 characters).
- Enable two-factor authentication (2FA).
- Keep software and antivirus updated.
- Do not open attachments from unknown senders.
- Use HTTPS websites for transactions.
- Log out of shared computers.

Intellectual Property and Licences
Intellectual Property (IP) refers to creations of the mind — software, music, literature, inventions.
- Copyright: automatic legal right protecting original creative works.
- Patent: protects inventions and new processes.
- Trademark: distinguishes brands (logos, names).
- Open Source Software: source code is freely available to use, modify, and distribute (e.g., Linux, Python).
- Freeware: free to use but source code is not shared.
- Proprietary Software: paid; usage governed by a license agreement.
Comparing licences
Microsoft Windows is proprietary — you buy a licence. The Linux kernel is open source — you can download, modify, and redistribute the source code under the GNU GPL licence.

E-Waste
Electronic waste (e-waste) is discarded electrical or electronic equipment. It contains hazardous materials (lead, mercury, cadmium) that harm the environment and human health if not disposed of properly.
Responsible e-waste disposal
- Return old devices to authorised recyclers (e-Daan Kendras in India).
- Donate working equipment to schools or NGOs.
- Erase personal data before discarding devices.

Health Concerns
Technology and physical health
Prolonged use of computers and smartphones can cause:
- Computer Vision Syndrome: eye strain, headaches from screen glare.
- Repetitive Strain Injury (RSI): wrist/finger pain from prolonged typing.
- Posture problems: back/neck pain from poor seating.
Preventive measures: follow the 20-20-20 rule (every 20 minutes, look at something 20 feet away for 20 seconds); use ergonomic furniture; take regular breaks.
---
Common mistakes
- Confusing copyright and patent — copyright protects expression (books, code); patents protect inventions/processes.
- Assuming open source = free of cost — open source refers to freedom to view/modify source code, not necessarily zero price.
- Ignoring passive digital footprint — even without actively posting, browsing itself generates data.

Summary
IT impacts society through digital footprints, cybercrime, privacy concerns, intellectual property rights, and e-waste. Responsible digital citizenship requires following netiquette, practising cybersecurity, respecting IP rights, disposing of e-waste properly, and being mindful of health impacts of prolonged technology use.
