The document discusses various types of software licenses: - Commercial software licenses which allow software to be sold for profit and include licenses like single-user, multi-user, and site licenses. They use mechanisms like activation codes and serial numbers to prevent piracy. - Freeware which is free to use but the copyright is maintained. It cannot be resold. - Shareware which is low-cost or free for a trial period. - Public domain which allows users to modify and redistribute the software. - Free and open source software (FOSS) which allows users freedom to modify and redistribute the software under the same license.
