### 1. What is the difference between the == and = operators?

**Answer:** The single equals sign = is the assignment operator that stores a value in a variable. The double equals == is the equality comparison operator that returns true or false. Confusing them is a common bug in conditions.

**Explanation:** = assigns; == compares for equality.

### 2. What is normalization in databases and why is it used?

**Answer:** Normalization organises tables to reduce redundancy and avoid update, insert, and delete anomalies by applying normal forms. It splits data into related tables linked by keys, trading extra joins for cleaner, consistent data.

**Explanation:** Reduce redundancy and anomalies via normal forms.

### 3. What is the difference between a class and an object?

**Answer:** A class is a blueprint that defines attributes and methods. An object is a concrete instance of a class with its own state. Many objects can be created from one class.

**Explanation:** Class is the blueprint; object is an instance of it.

### 4. What is exception handling and why is it important?

**Answer:** Exception handling manages runtime errors gracefully using constructs like try, catch, and finally, so the program can recover or fail cleanly instead of crashing. It separates error handling from normal logic and keeps resources released.

**Explanation:** Handle runtime errors gracefully with try, catch, finally.

### 5. What is the difference between TCP and UDP?

**Answer:** TCP is connection oriented and reliable, with handshakes, ordering, and retransmission, suited to web and email. UDP is connectionless and unreliable but faster and lower overhead, suited to streaming, gaming, and DNS.

**Explanation:** TCP reliable and ordered; UDP fast and connectionless.

### 6. What is an API?

**Answer:** An API (Application Programming Interface) is a defined set of rules that lets software components communicate. It exposes operations and data formats (for example a REST API over HTTP) so clients can use a service without knowing its internals.

**Explanation:** A contract that lets software components communicate.

### 7. Coforge includes a spoken communication round (SpeechX). How should you prepare for it?

**Answer:** Practise speaking clearly at a steady pace, read passages aloud, and record yourself to check pronunciation and fillers. Ensure a quiet room, a working mic and webcam, and a stable connection. Focus on clarity and confidence rather than a heavy accent.

**Explanation:** Practise clear speech; ready a quiet room, mic, and webcam.

### 8. Tell me about yourself.

**Answer:** Give a crisp 60 to 90 second overview: your degree, key skills, a project or internship with its result, and why Coforge interests you. Keep it structured and relevant to the role.

**Explanation:** Structured pitch: background, skills, project, fit.
