The types of internal tables are: standard table, sorted table and hashed table. Hash table is the most efficient of the three with a constant response time.

The internal tables could be catogrised into two.

  indexed   : standard and sorted tables.
  nonindexed: hash tables.

standard table: it is the one we use generally.In this the data is not sorted and the only thing we can do is just process the data with out any restriction on it.

sorted tables: it works in two different manner.
                       Frist one: is similar to standard table but the only difference is the data will be filled in a particular manner either ascending or descending. 
                      Second one: u can also fill the table keeping any field as primary key.now the data will be filled based on that particular key.

Hash tables:   u can use this when u want  to fill your  internal table avoiding the duplication of data.it never permits the duplicate record to be stored in a internal table
