What is a shareware programme.Whether we have to purchase the programme to fully use it.

   Shareware is an older term that most software developers now try to steer clear of because of certain bad connotations associated with the term.  Now software developers use the terms full and trial versions (or similar terms) instead of shareware.
   A shareware program is a program that lets you download it and try it for free.  They often have certain limitations on them until you buy them.  The limitation can range from a nag screen to disabling features.  Some shareware programs are fully functional for a certain amount of days.
   The advantage is that you get to see the product and try it before you buy it.
   If the program is totally free and never has to be purchased, it is called freeware.  Shareware includes freeware.
