Difference between CTE(Common Table Expressions) and Table Variable in SQL Server

Difference between CTE(Common Table Expressions) and Table Variable in SQL Server :
  CTE Table Variable
1 CTE is like Derived Table or even like a sub-query. So it doesn't store on disk. Table variable is like Temporary Table. It stores on disk.
2 You cannot create any index on CTE You can create clustered index but can not create Non clustered index
3 Scope of CTE  is within the session Scope of table variable is within the batch
