IEnumerable:
It is the parent interface for all non-generic collections in System.Collections namespace like ArrayList, HasTable etc. that can be enumerated. For the generic version of this interface as IEnumerabel<t> which a parent interface of all generic collections class in System.Collections.Generic namespace like List<> and more.

Some key points should know:
1. It belongs to System.Collections namespace.
2. It is the best way to write query on collections data type like List, Array etc.
3. It is the return type for LINQ to Object and LINQ to XML queries.
4. It doesn't support lazy loading. So it's not a recommended approach for paging kind of scenarios.
5. Extension methods are supports by IEnumerable takes functional abjects for LINQ Query's.

IQueryable:
IQueryablel interface is intended for implementation by query providers. It is only supposed to be implemented IQueryable<t>, the standard query operators cannot be used on the provider's data source.

The IQueryable interface inherits the IEnumerable interface so that if it represents a query, the result of that query can be enumerated.

Some key points should know:
1. It belongs to System.Linq namespace.
2. It is the best way to write query data like remote database, service collections.
3. It is the return type of LINQ to SQL queries.
4. It support lazy loading so we can also use in paging kind of scenarios.
5. It implements IEnumerable so indirectly it's also supports Extensions methods.
