  • Online Education & E-Learning: Facilitates distance learning through virtual classrooms, tutorials, and online courses.

  • Entertainment: Offers access to streaming media, music, online games, and social media networks.

2. Describe unethical practices on the internet.

Unethical practices refer to actions on the internet that violate moral standards, breach privacy, or harm others. Key examples include:

  • Plagiarism: Copying someone else's work, text, or ideas without proper attribution and presenting them as your own.

  • Cyberbullying: Using digital media to harass, intimidate, threaten, or humiliate others online.

  • Piracy: Unauthorized downloading, copying, or sharing of copyrighted content (such as software, movies, or music) without paying.

  • Phishing & Fraud: Deceiving users to steal sensitive personal information like banking credentials or passwords.

3. Explain phishing with a real-life scenario.

Phishing is a cyber attack technique where fraudsters send fake emails or messages that appear to come from legitimate organizations (like banks or popular websites) to trick individuals into revealing sensitive personal or financial information.

  • Real-life Scenario:

    Suppose Rahul receives an urgent email that looks exactly like it came from his bank, warning him that his account will be suspended unless he updates his password immediately. The email contains a link to a fake bank website. When Rahul enters his login details on this page, the attacker captures his username and password, gaining unauthorized access to his real bank account.

4. Why is it important to use a strong password?

  • Prevents Unauthorized Access: A strong password makes it significantly harder for hackers or malicious software to guess or crack your account credentials.

  • Protects Personal & Financial Data: It safeguards sensitive personal information, online payment details, and private communications from identity theft.

  • Prevents Account Hijacking: It reduces the risk of attackers taking over your social media or email accounts to spread malware or impersonate you.

5. Explain digital footprint and its types.

A digital footprint is the trail of data and online activity left behind by a user while navigating the internet, including visited websites, social media posts, and online communications.

Types of Digital Footprint:

  • Active Digital Footprint: Created when a user intentionally submits data online.

    • Example: Posting photos on social media, filling out online registration forms, or sending emails.

  • Passive Digital Footprint: Created when data is collected about a user without their explicit or active involvement.

    • Example: Websites tracking browsing history via cookies, or logging IP addresses and location data automatically.
