I am quite confused about the difference between an index on table and index on view (Indexed View). Please clarify it.

A view is a database object that allows generating a logical subset of data from one or more tables. A table is a database object or an entity that stores the data of a database. The view depends on the table. The table is an independent data object.
Indexed View(s) An indexed view is a view where the result set from the query (the view definition) becomes materialized in lieu of the virtual table result set of a standard (non-indexed) view. Many times we see that an indexed view would be created to help improve performance.
A table of contents is a list of the parts of a book or document while an index is a list of important words, concepts, and other useful materials in a book or document.
Table indexes work the same way as an index in a book does, allowing you to quickly find information contained in the table. Table indexes are commonly made by using one column in a table, but can also contain more than one column. Indexed columns are the columns that are used within your queries to find information.
There really is none. The index on both table or view basically serves to speed up searches.
The main thing is: views normally do not have indices. When you add a clustered index to a view, you're basically "materializing" that view into a system-maintained, always automatically updated "pseudo-table" that exists on disk, uses disk space just like a table, and since it's really almost a table already, you can also add additional indices to an indexed view.
So really - between a table and an indexed view, there's little difference - and there's virtually no difference at all between indices on tables and an indexed view.
