normally we have to buy a program, but sometimes software is free. software is called freeware if its author chooses to provide it free to all. however, freeware may or may not copyrighted that is, have restriction of use placed upon it. uncopyrighted software is considered to be in the public domain and may be used, or even altered, without restriction. sometime freeware, perhaps written by a student or educator,is offered without free and without copyright. other freeware may be offered to the public as a marketing tool by a major manufacturer, who will most certainly copyright it and maintain all ownership rights. software called shareware is also given away free, but the maker hopes for voluntary payment that is,he or she hope that you like it well enough to send him some money.
