Commercial software is computer software sold for
commercial purposes or that serves commercial purposes.
Commercial software is most often proprietary software,
but free software is also used as commercial software.
All or parts of software packages and services that
support commerce are increasingly made available as free
software, |

|
|
Computer software which is made
available for use free of charge, for an unlimited time,
as opposed to shareware where the user is required to
pay .
Authors of freeware often want to give
something to the community, but also want credit for
their software and to retain control of its future
development.

Open source describes the principles and
methodologies to promote open access to the and design process for various
goods, products, resources and technical conclusions or
advice. The term is most commonly applied to the source
code of software that is made available to the general
public with either relaxed or non-existent intellectual
property restrictions. This allows users to create
user-generated software content through either
incremental individual effort, or collaboration.

Software development is sometimes understood to
encompass the processes of software engineering combined
with the research and goals of software marketing to
develop computer software products.This is in contrast
to marketing software, which may or may not involve new
product development.
It is often difficult to isolate whether engineering
or marketing is more responsible for the success or
failure of a software product to satisfy customer
expectations. This is why it is important to understand
both processes and/or facilitate collaboration between
both engineering and marketing in the total software
development process. Engineering and marketing concerns
are often balanced in the role of a project manager that
may or may not use that title.
There are
mainly two types of businesses in the software industry;
those developing proprietary software such as Microsoft,
and those developing open source software. Developing
proprietary software is costly and involves software
licensing and the need to protect the software from
cracking and piracy.
