What is Full Stack development?
Full Stack development involves developing both the front end and back end of the web application/website at the same time. This process includes three layers:
-
Presentation layer (frontend part responsible for user experience)
-
Business logic layer (backend part refers to the server side of the application)
-
Database layer

What is Inversion of Control (IoC)?
Inversion of Control (IoC) is a broad term used by software developers for defining a pattern that is used for decoupling components and layers in the system. It is mostly used in the context of object-oriented programming. Control of objects or portions of a program is transferred to a framework or container with the help of Inversion of Control. It can be achieved using various mechanisms such as service locator pattern, strategy design pattern, factory pattern, and dependency injection.
What is Dependency Injection?
Dependency Injection is a design pattern by which IoC is executed. Injecting objects or connecting objects with other objects is done by container instead of by the object themselves. It involves three types of classes.
- Client class: It depends on the service class.
- Service class: It provides service to the client class.
- Injector class: It injects service class objects into the client class.
What is multithreading and how it is used?
The main purpose of multithreading is to provide multiple threads of execution concurrently for maximum utilization of the CPU. It allows multiple threads to exist within the context of a process such that they execute individually but share their process resources.

What is the Observer pattern?
The purpose of the Observer pattern is to define a one-to-many dependency between objects, as when an object changes the state, then all its dependents are notified and updated automatically. The object that watches on the state of another object is called the observer, and the object that is being watched is called the subject.
What’s the difference between a Full Stack Engineer and a Full Stack Developer?

What is polling?
Polling is a method by which a client asks the server for new data frequently. Polling can be done in two ways: Long polling and Short Polling.
- Long polling is a development pattern that surpasses data from server to client with no delay.
- Short polling calls at fixed delays and is based AJAX-based.
