hi,

  workarea is used to store structure data,i.e. especially we will use workarea to transfer data to internal table ,thereby to data base table....

Internal table is used to store more than one record.Internal table is like a program level  memory area to store one or more records. At the end of each program the internal tables,workarea are deleted from the abap memory...

Select statements are SQL(Structured Query Language) statements used to fetch/select the records from the database into workarea/internal table...
