Hello Prakash, Since your asking so many questions i am sharing links instead of typing to save time,please go through belows 1)List the OOPS in C#: Class, Method, Object, Encapsulation, Abstraction, Information Hiding, Inheritance Polymorphism, Message Passing, Dynamic Binding etc. https://www.aspneto.com/oop-concepts-object-oriented-programming-concepts-with-examples.html 2) Explain the access modifiers and the modifiers are how to protect data: https://www.c-sharpcorner.com/UploadFile/puranindia/what-are-access-modifiers-in-C-Sharp/ https://www.c-sharpcorner.com/blogs/encapsulation-and-access-specifiers-in-c-sharp 3) what is a property (get; set;) please explain: https://www.c-sharpcorner.com/UploadFile/3d39b4/property-in-C-Sharp/ https://www.w3schools.com/cs/cs_properties.asp https://www.c-sharpcorner.com/article/understanding-properties-in-C-Sharp/ https://www.tutlane.com/tutorial/csharp/csharp-properties-get-set 4)what is the difference between LINQ and lambda expression? Language-Integrated Query (LINQ) is a set of features introduced in Visual Studio 2008 that extends powerful query capabilities to the language syntax of C# and Visual Basic. A lambda expression is an anonymous function that you can use to create delegates or expression tree types. By using lambda expressions, you can write local functions that can be passed as arguments or returned as the value of function calls. Linq uses Lambda expression in order to execute some of its functionalities. Example: new [] { "Dan" , "Yossi" , "Ben" }.Where(item => item.Length == 3); Lambda expression: item => item.Length == 3 Linq: (from item in ( new [] { "Dan" , "Yossi" , "Ben" }) where item.Length == 3) 5)how to get a large amount of data from the database properly: https://softmedialab.com/blog/database-choice-for-large-data-volume/ https://dba.stackexchange.com/questions/188667/best-database-and-table-design-for-billions-of-rows-of-data

OOP reflects the real world behavior of how things work. It is important because It make visualization easier because it is closest to real world scenarios. You can reuse the code, this saves time, and shrinks your project. Once you know the concept, it makes you a cooler coder among your friends ;) . There are 3 basic features of object oriented programming language: Inheritance Polymorphism Encapsulation By using these features you can easily reuse your program or part of your program.
