10+ PERFORMALYTIC (INDIA) Interview Questions and Answers

Key concepts of Object-Oriented Programming (OOP) include encapsulation, inheritance, polymorphism, and abstraction.

• Encapsulation: Bundling data and methods that operate on the data into a single unit (object).

• Inheritance: Allowing a class to inherit properties and behavior from another class.

• Polymorphism: The ability for objects of different classes to respond to the same method in different ways.

• Abstraction: Hiding the complex implementation details and showing only the nec...read more

Linux is preferred over Windows in high security systems due to its open-source nature, strong security features, and minimal attack surface.

• Linux is open-source, allowing for greater transparency and customization to meet security needs.

• Linux has a strong permission system, making it easier to control access to sensitive data and resources.

• Linux has a smaller attack surface compared to Windows, reducing the risk of vulnerabilities being exploited.

• Linux distributions like Cen...read more

• Identifying the root cause of the problem

• Breaking down the problem into smaller tasks

• Collaborating with team members to brainstorm solutions

• Seeking advice from subject matter experts

• Testing different solutions to find the most effective one

The candidate is asked to write code for generating Fibonacci series and finding the second largest number in an array.

• For Fibonacci series, start with 0 and 1, then add the previous two numbers to get the next number in the series.

• To find the second largest number in an array, sort the array in descending order and return the element at index 1.

TCP (Transmission Control Protocol) and UDP (User Datagram Protocol) are two different protocols used for transmitting data over the internet.

• TCP is a connection-oriented protocol that guarantees delivery of data packets in the correct order.

• UDP is a connectionless protocol that does not guarantee delivery of data packets or their order.

• TCP is used for applications that require reliable and ordered delivery of data, such as web browsing and email.

• UDP is used for applications ...read more

The OSI Model is a conceptual framework that standardizes the functions of a telecommunication or computing system into seven distinct layers.

• The OSI Model stands for Open Systems Interconnection Model.

• It helps in understanding how different networking protocols work together.

• The seven layers are: Physical, Data Link, Network, Transport, Session, Presentation, and Application.

• Each layer has specific functions and communicates with adjacent layers.

• For example, HTTP operates at...read more

OOPS (Object-Oriented Programming) concept is a programming paradigm based on the concept of objects.

• OOPS focuses on creating objects that contain data and methods to manipulate that data.

• Encapsulation, inheritance, polymorphism, and abstraction are key principles of OOPS.

• Encapsulation involves bundling data and methods that operate on the data into a single unit.

• Inheritance allows one class to inherit properties and behavior from another class.

• Polymorphism enables objects to...read more

Opps in Java stands for Object-Oriented Programming concepts.

• Opps in Java refers to the principles of Object-Oriented Programming such as Inheritance, Encapsulation, Polymorphism, and Abstraction.

• It allows for creating modular, reusable, and maintainable code by organizing data and behavior into objects.

• Example: Creating classes and objects, using inheritance to create subclasses, and implementing interfaces.
