Difference between IEnumerable and IQueryable #Csharp #techinterviews #interviewpreparation #java

In C#, IEnumerable and IQueryable are both used to query collections of data, but they have different behaviors:

Execution: IEnumerable executes queries on the client-side, meaning that the query is performed after all the data is returned from the server. IQueryable executes queries on the server-side, meaning that the query is performed on the database before the data is returned to the client.

Deferred execution: IEnumerable supports deferred execution, which means that the query is not executed until the data is actually needed. IQueryable also supports deferred execution, but because it executes queries on the server-side, it can often optimize the query before executing it.
