VI. Answer the following (3 × 5 = 15)

1. Timeline of AI:

   • 1950s: Birth of AI (Turing Test, early AI programs)

   • 1960s-70s: Development of problem-solving and logic-based AI

   • 1980s: Expert systems boom

   • 1990s: AI applied in games (chess), machine learning begins

   • 2000s: AI in robotics, natural language processing

   • 2010s-present: Deep learning, AI assistants, smart homes, smart cities

2. How internal linking is done on a web page:

   • Internal links connect sections within the same page.

   • Steps:

     1. Give a section an id, e.g., <h2 id="top">Header</h2>

     2. Link to it using <a href="#top">Go to top</a>

3. Various form controls in HTML:

   • Text box (<input type="text">)

   • Password field (<input type="password">)

   • Radio buttons (<input type="radio">)

   • Checkboxes (<input type="checkbox">)

   • Submit button (<input type="submit">)

   • Reset button (<input type="reset">)

   • Dropdown list (<select>), Text area (<textarea>), File input (<input type="file">)

4. How to specify multiple conditions while designing a query:

   • In SQL, use logical operators like AND, OR, and NOT

   • Example: SELECT * FROM Students WHERE Class='VII' AND Marks>80;

5. Purpose of a key in a relational data model:

   • A key uniquely identifies a record in a table

   • Types: Primary Key (unique identifier), Foreign Key (links tables), Candidate Key (possible unique identifiers)
