2. Technical Questions (For IT & Engineering)
Q8: Explain object-oriented programming principles.
A: OOP principles include:
Encapsulation: Hiding data inside a class and restricting direct access.
Abstraction: Showing only essential details while hiding complexity.
Inheritance: Acquiring properties of one class in another.
Polymorphism: Using the same method in different ways.
Q9: What is the difference between SQL and NoSQL databases?
A:
SQL (Structured Query Language) databases use tables and structured data (e.g., MySQL, PostgreSQL).
NoSQL databases are schema-less and handle unstructured data, suitable for scalability (e.g., MongoDB, Cassandra).
Q10: How does a compiler work?
A: A compiler converts high-level code into machine code in multiple phases: Lexical Analysis, Syntax Analysis, Semantic Analysis, Optimization, and Code Generation.
Q11: What is the time complexity of quicksort?
A:
Best/Average Case: O(n log n)
Worst Case: O(n²) (when pivot selection is poor)
Q12: Explain the concept of normalization in databases.
A: Normalization reduces redundancy by dividing tables into smaller, related tables (1NF, 2NF, 3NF, etc.).
Q13: What is the difference between TCP and UDP?
A:
TCP (Transmission Control Protocol): Reliable, connection-based, used for emails, web browsing.
UDP (User Datagram Protocol): Faster, connectionless, used for gaming, streaming.
Q14: How does garbage collection work in Java/Python?
A: Garbage collection automatically deallocates unused memory. Java uses JVM’s GC, while Python’s GC uses reference counting and cyclic garbage collection.
