Best Practices to Minimize Risk:

1. Regularly audit and delete third-party browser cookies.
2. Use private browsing / incognito mode on shared workstations.
3. Enable Multi-Factor Authentication (MFA / 2FA) across all digital accounts.

2. Intellectual Property Rights (IPR)

Intellectual Property (IP) refers to creations of the mind: inventions, literary and artistic works, symbols, names, and images used in commerce.

IPR Category	What It Protects	Validity / Term	Real-World Example
Copyright	Original literary works, source code, books, music, artistic films.	Lifetime of author $+60\text{ years}$	Python library code, a novel
Patent	Novel, non-obvious industrial inventions, processes, and machines.	$20\text{ years}$ from filing date	New semiconductor manufacturing method
Trademark	Distinctive signs, logos, brand names, slogans identifying commercial origin.	$10\text{ years}$ (Renewable indefinitely)	Apple logo ($\text{text{textregistered}}$), Nike 'Swoosh'

Plagiarism vs Copyright Infringement

• Plagiarism: Stealing another person's ideas or writing and claiming them as your own work without attribution (ethical violation).
• Copyright Infringement: Unauthorized copying, distribution, or commercial use of copyrighted material without the owner's legal permission (legal offense).

Key Differences: Hacker vs Cracker

• Ethical Hacker (White Hat): A cybersecurity specialist who penetrates systems with prior authorization to identify and fix security vulnerabilities.
• Cracker (Black Hat): A cybercriminal who illegally breaks into computer networks with malicious intent to steal, deface, or destroy data.

6. E-Waste Management & Green Computing

Electronic Waste (E-Waste) refers to discarded electronic devices like old computers, mobile phones, printers, and monitors.

Toxic Heavy Metals in E-Waste

• Lead ($\text{Pb}$): Found in CRT monitors and solder; causes severe central nervous system and kidney damage.
• Mercury ($\text{Hg}$): Found in flat-panel switches and backlights; causes brain and neurological disorders.
• Cadmium ($\text{Cd}$): Found in rechargeable batteries and resistors; damages bone structure and kidneys.

Safe E-Waste Disposal Protocols

1. Reduce, Reuse, Recycle: Upgrade components rather than replacing whole units.
2. Authorized E-Waste Recyclers: Dispose through government-certified e-waste collection centers.
3. Manufacturer Buy-Back / Take-Back Programs: Return old electronics to original manufacturers for safe disassembly.

7. Ergonomics & Health Guidelines

• Screen Distance: Keep monitor $20-24\text{ inches}$ away, with top of screen at or slightly below eye level.
• 20-20-20 Rule: Every 20 minutes, look at an object 20 feet away for at least 20 seconds to avoid digital eye strain.
• Postural Health: Use an ergonomic chair with lumbar support; keep thighs and forearms parallel to the floor to prevent Repetitive Strain Injury (RSI).
