TCS Computer Engineer Interview Questions, Process, and Tips

It is very easy to clear aptitude in tcs

We need to learn little coding techniques

Q1. How mant normalization forms are there
Ans. 
There are 5 normalization forms in database design.
• 1. First Normal Form (1NF) - Eliminate repeating groups and ensure each field contains only atomic values.

• 2. Second Normal Form (2NF) - Meet 1NF requirements and all non-key attributes are fully functional dependent on the primary key.

• 3. Third Normal Form (3NF) - Meet 2NF requirements and eliminate transitive dependencies.

• 4. Boyce-Codd Normal Form (BCNF) - Meet 3NF req...read more

Q2. Explian about 3 normalization
Ans. 
Normalization is the process of organizing data in a database to reduce redundancy and improve data integrity.
• Normalization helps in reducing data redundancy by organizing data into multiple tables.

• It improves data integrity by ensuring that each piece of data is stored in only one place.

• There are 3 main forms of normalization: 1NF, 2NF, and 3NF.

Q4. What is the use of abstract class?
Ans. 
Abstract class is used as a blueprint for other classes to inherit from, providing common methods and properties.
• Provides a template for other classes to follow

• Can contain abstract methods that must be implemented by child classes

• Cannot be instantiated on its own, only used for inheritance

• Allows for code reusability and organization

• Example: Shape class with abstract method calculateArea, Circle and Square classes inher

Q5. What is the sue of interface?
Ans. 
Interfaces in computer engineering are used to define a contract for classes to implement, allowing for polymorphism and loose coupling.
• Interfaces define a set of methods that a class must implement.

• They allow for polymorphism, where objects of different classes can be treated as objects of the same interface.

• Interfaces promote loose coupling between classes, making code more modular and easier to maintain.

• Examples of ...read more
