Hi Srk's

I = parameters like logos, pfstatus ,sy-repid,structure name,User Command,Buffer and so on.( input to function modules )

IT = internal tables like fieldcat,sorting,filtering,hide,save ,variantand events in Itab ( input to function module as internal tables )

IS = layout ( input to function module as structures )

Plz refer the below link for better understanding,

its naming convention..

I represent Input to function module, and O represent 'Output' from function module. In same way IS represent input with structure , IT represent Input with internal table.

You can use this convention while defining FORM or METHODS, its a good practice..
