The different software
There are 3 major types of computer
software, regardless of the operating system of your computer (GNU / Linux,
Windows or Mac).
1) Proprietary and paid software
These software made by software companies
are sold to the user when buying his computer, boxed in specialty stores or on
the Internet.
But beware, what is sold is not the right
of ownership of the user on the software but only a right of use, it is a user
license.
Example: The Windows operating system is
of this type.
It is not possible to keep Windows for
you when selling your old computer and it is not possible to resell it
separately from the machine.
First pitfall therefore, the license of
simple use, second, the software is under copyright (= the source code of the
software is closed and protected), it is not possible for a user whatever his
skill level in computer science to modify the software for its needs or to add
new potentialities.
Only the company holding the property
license has this right, hence the commercial genesis of innumerable paid
updates.
The price of user licenses can be
significantly increased depending on whether the license for use relates to 1
or more networked stations or not.
The vast majority of software on Windows
and Mac are of this type, they are rather rare in GNU / Linux.
Shareware
Very often the paid software is
sharewares. The latter is for an author to release a complete version of his
software for free circulation so that the public can test it without making a
financial commitment. This mode of distribution can be likened to a period of
"free trial" during which the author offers you the opportunity to
evaluate software in the most obvious and effective way: by using it in your
usual work context.
Freely downloadable, a shareware is not
free. A moral contract binds its author to whoever installs the software. It
states that the user of the shareware must, if he wants to use the product and
even keep it on his computer at the end of the evaluation period pay the price
of the license. Clearly: once past thirty days trial of a shareware, it will be
necessary to go to the cashier if one wishes to keep the usufruct. Otherwise we
will have to rest the software on its shelf, in other words, uninstall it, if
for any reason, we do not want to acquire it.
However it will be noticed that the
authors of sharewares, to remedy the abuses, voluntarily or not, also take more
and more often care to disable certain functionalities of their software to
incite the public to remunerate them.
The purpose of this type of application
is to gently lure the client by providing an overview of the capabilities of
the software. But just a preview because many of its features will be
restrained.
For example, with the demo version of the
famous Photoshop you will not be able to print, save, or even copy and paste.
It goes without saying that downloading a demo does not commit you to the
extent that you will not be able to really exploit the software!
