what are all the different types of indexes in sql

1"There are two types of Indexes in SQL Server
2
31.	Clustered Index
4
5A clustered index defines the order in which data 
6is physically stored in a table. Table data can 
7be sorted in only way, therefore, there can be only 
8one clustered index per table. In SQL Server, 
9the primary key constraint automatically creates a 
10clustered index on that particular column.
11
122.	Non-Clustered Index
13
14A non-clustered index doesn’t sort the physical 
15data inside the table. In fact, a non-clustered 
16index is stored at one place and table data is 
17stored in another place. This is similar to a 
18textbook where the book content is located in o
19ne place and the index is located in another. 
20This allows for more than one non-clustered index per table."
