11. Application Software
Software can be purchased or acquired as:
 Shareware:
 Usually intended for sale after a trial period.
 Freeware:
 Free software but with copyright restrictions .
 Licenses:
A software is a legal instrument (usually by way of contract law)
governing the usage or redistribution of software. All software is
copyright protected, except material in the public domain
 Key Generator
A license or product key generator (keygen) is a computer program
that generates a product licensing key, serial number, or some other
registration information necessary to activate for use a software
application

12. Shareware
 Is provided to users without payment on a trial basis and
is often limited by any combination of functionality.
 Shareware is often offered as a download from an
Internet website or as a compact disc to give buyers the
opportunity to use the program and judge its usefulness
before purchasing a license for the full version of the
software.

13. Shareware cont’d
 Firms with superior software thus have an incentive to
offer samples, except if their product is already well
known,
 or as a full version but for a limited trial period of time.
Once the trial period has passed, the program may stop
running until a license is purchased.

14. Freeware
 Freeware (from "free" and "software") is computer
software that is available for use at no cost or for an
optional fee, but usually with one or more restricted
usage rights.
 Freeware is in contrast to commercial software, which is
typically sold for profit, but might be distributed for a
business or commercial purpose in the aim to expand
the marketshare of product.
 Popular examples of freeware include Firefox, Google
Chrome, 7-Zip and Adobe Flash Player.

15. Software license
 A software license is a legal instrument (usually by way
of contract law) governing the usage or redistribution of
software. All softwares are copyright protected except
public domain softwares.
 Public domain software is software that has been
placed in the public domain, in other words there is
absolutely no ownership such as copyright, trademark,
or patent. Unlike other classes of licenses, there are no
restrictions as to what can be done with the software.

without any attribution.
 A typical software license grants an end-user permission
to use one or more copies of software giving user
exclusive rights under copyright law.
