Internal Tables are:
STANDARD table : Key access to a standard table uses a
linear search. This means that the time required for a
search is in linear relation to the number of table entries.
You should use index operations to access standard tables.
SORTED table: Defines the table as one that is always saved
correctly sorted. Key access to a sorted table uses a binary
key. If the key is not unique, the system takes the entry
with the lowest index. The runtime required for key access
is logarithmically related to the number of table entries.
HASHED table: Defines the table as one that is managed with
an internal hash procedure You can only access a hashed
table using the generic key operations or other generic
operations ( SORT, LOOP, and so on). Explicit or implicit
index operations (such as LOOP ... FROM oe INSERT itab
within a LOOP) are not allowed.
INDEX table:
A table that can be accessed using an index. Index table is
only used to specify the type of generic parameters in a
FORM or FUNCTION. That means that you can't create a table
of type INDEX. Standard tables and sorted tables are index
tables.
Syntax : DATA itab TYPE table type of line type [WITH
UNIQUE/NON-UNIQUE KEY ] [Iinitial size n] [WITH HEADER LINE]

Ans : DESCRIBE TABLE <itab-Name> LINES <variable>

internal table
