NAT is used in networking to allow multiple devices on a local network to share a single public IP address.
NAT stands for Network Address Translation.
It allows a router to translate private IP addresses on a local network to a single public IP address when communicating over the internet.
NAT helps conserve public IP addresses and adds an extra layer of security by hiding the internal network structure.
Example: A home n...

A pipeline is a series of interconnected steps or stages in a process, where output of one step is input to the next step.
Pipeline is commonly used in software development for continuous integration and continuous delivery processes.
Each step in the pipeline performs a specific task, such as building, testing, and deploying code.
Pipeline automation tools like Jenkins, GitLab CI/CD, and Azure DevOps help in managing and

Abstract classes can have implementation details while interfaces cannot.
Abstract classes can have method implementations while interfaces cannot.
A class can inherit only one abstract class but can implement multiple interfaces.
Abstract classes can have access modifiers on their members while interfaces cannot.
Interfaces are used to define a contract for classes to implement.
Abstract classes are used to provide a commo

A singleton class is a class that can only have one instance created and provides a global point of access to that instance.
Singleton classes are often used for logging, caching, database connections, and thread pools.
They typically have a private constructor to prevent instantiation from outside the class.
The class itself usually provides a static method to access the single instance.
Oops Pillars are the four main concepts of Object-Oriented Programming: Inheritance, Encapsulation, Polymorphism, and Abstraction.
Inheritance: Allows a class to inherit properties and behavior from another class.
Encapsulation: Bundles data and methods into a single unit, protecting data from outside interference.
Polymorphism: Allows objects to be treated as instances of their parent class, enabling flexibility in code.

Dependency injection is a design pattern in which components are given their dependencies rather than creating them internally.
Allows for easier testing by mocking dependencies
Promotes loose coupling between components
Improves code reusability and maintainability
Examples: Constructor injection, Setter injection, Interface injection

I took an MCQ SQL coding test conducted by the company and scored 9 out of 10, demonstrating strong SQL skills and knowledge. It was a positive validation of my abilities in handling SQL queries efficiently.
During the technical round SQL test conducted by the company, I faced predominantly technical questions to assess my SQL proficiency. Additionally, there was a machine round where I had to write and demonstrate SQL code, showcasing my practical skills in a real-world scenario. It was a challenging yet rewarding experience that allowed me to showcase my SQL expertise effectively.
Snapshot is a copy of a system at a specific point in time, while cloning is creating an exact duplicate of a system.
